(DSM/IRFU/SPhN)\nNuclear reactions on hydrogen CH2 or CD2 targets in inverse kinematics are extensively used wi th radioactive beams. This is the case\, for example\, for transfer reacti ons or resonant elastic scattering. Cryogenic targets may be used to impro ve the luminosity and remove the contribution of C atoms. However\, for lo w incident beam energies\, the thickness of the cryogenic target is a cruc ial parameter to achieve the detection of the reaction products. The aim o f the CHyMENE project is first to produce a thin target in the 50-100µm r ange by a continuous extrusion technique. A film of solid hydrogen flows i n a given plane (perpendicular to the beam axis in our case) and will be e vacuated after irradiation. No additional Mylar-type window will be used.\ n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=24&sessionId=8&c onfId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=24&sessionId=8& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Onset of collectivity in neutron-rich Fe isotopes DTSTART;VALUE=DATE-TIME:20100607T074000Z DTEND;VALUE=DATE-TIME:20100607T080000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-25@cern.ch DESCRIPTION:Speakers: Dr. LJUNGVALL\, Joa (CSNSM Orsay)\nThe lifetimes of the first excited 2+ states in 62Fe and 64Fe have been measured in an expe riment at GANIL using the Recoil-Distance Doppler Shift technique. The iro n nuclei where populated in multi-nucleon transfer reactions between a 238 U beam at 6.5MeV/A and a 64Ni target. A degrader foil at micrometer distan ces from the target was used to slow the reaction products before entering the VAMOS spectrometer for identification. The Doppler shift of the gamma rays emitted before and after the degrader foil was measured with the EXO GAM germanium detector array. \n\nThe lifetimes give evidence for a strong increase in collectivity from 62Fe to 64Fe. The results are compared to n ew large-scale shell model calculations and HFB-based configuration mixing calculations. The large B(E2) value in 64Fe can be related to the occupat ion of the neutron g9/2 and d5/2 orbitals. Many parallels are found betwee n the neutron-rich Fe isotopes below 68Ni and the so-called 'island if inv ersion' around 32Mg.\n\nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=25&sessionId=5&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=25&sessionId=5& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:FIRST RESULTS OF REACTIONS INDUCED WITH EXOTIC BEAMS IN THE REGION OF 11Be WITH CHIMERA ARRAY DTSTART;VALUE=DATE-TIME:20100608T132000Z DTEND;VALUE=DATE-TIME:20100608T134000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-26@cern.ch DESCRIPTION:Speakers: GRASSI\, L.

At K VI we are developing experiments to measure Atomic Parity Violation (APV) and Time Reversal Violation (TRV) using Ra ions and atoms\, respectively. The APV measurements aim to improve on the accuracy of weak charge measure ments. The sensitivity scales faster than the atomic number of the atom an d therefore Ra ions may improve on the current best accuracy obtained with Cs. Limits on TRV can be obtained by searching for a permanent Electric D ipole Moment (EDM) also here Ra is orders of magnitude more sensitive than the current best limit on the EDM using Hg atoms. Current focus is on mea suring atomic properties of Ra ions and atoms. We describe the production and trapping of Ra atoms and ions and the first measurements\, such as iso tope shifts and hyperfine interactions of excited states\, which address t he accuracy of theoretical calculations. The latter will be essential for the interpretation of the fundamental experiments.\n\nhttp://indico.cern.c h/contributionDisplay.py?contribId=21&sessionId=25&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=21&sessionId=25 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Secondary neutrons as the main source of the neutron rich fission residues production after the bombardment of a thick U target by 1 GeV pro tons: experimental evidences for Cs isotopes DTSTART;VALUE=DATE-TIME:20100608T084000Z DTEND;VALUE=DATE-TIME:20100608T090000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-22@cern.ch DESCRIPTION:Speakers: BARZAKH\, Anatolij (Petersburg Nuclear Physics Insti tute)\nTo predict isotope yields in the future ISOL installations it is of crucial importance to understand properly the mechanism of isotope produc tion in thick target. The present work seems to be a step toward this unde rstanding.\nExperimental yields of the mass separated Cs isotopes produced by 1 GeV proton beam in thick U targets (with the thicknesses 6.5\, 91 an d 146 g/cm2) have been analyzed in the framework of diffusion-effusion mod el. The applicability of the model has been shown by the analysis of the F r isotopes yields. Comparison of the neutron rich and neutron deficient Cs isotopes production efficiencies allows to divide contributions from the direct reaction (p+238U) and secondary reaction ((secondary n)+238U) in th e neutron rich Cs isotopes production. For 146Cs\, for example\, the secon dary neutron contribution is greater than the direct reaction contribution from 10 to 40 times depending on the thickness and geometry of a target m aterial. Simple calculation of the “neutron contribution” with the kno wn secondary neutron multiplicity and the isotope production cross-section s in the reaction (n14MeV+238U) describes these data fairly well.\n\nhttp: //indico.cern.ch/contributionDisplay.py?contribId=22&sessionId=9&confId=61 310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=22&sessionId=9& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Use of RIB facilities for producing isotopes for cancer treatment by DαRT DTSTART;VALUE=DATE-TIME:20100611T080000Z DTEND;VALUE=DATE-TIME:20100611T082000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-23@cern.ch DESCRIPTION:Speakers: Prof. KELSON\, Itzhak (School of Physics and Astrono my\, Tel Aviv University\, Tel Aviv\, Israel)\nAlpha particles are well kn own for their effectiveness against cancer cells. A few alpha particles pa ssing through the cell DNA are sufficient to destroy it or to stop its mul tiplication. However\, the short range (less than 0.1 mm) of naturally ava ilable alpha particles has so far prohibited their use as a practical ther apeutic agent. Diffusing Alpha-emitters Radiation Therapy (DαRT) is a new modality for utilizing alpha particles for treating solid tumors which ov ercomes this limitation. Instead of inserting into a tumor a source emitti ng alpha particles\, one inserts a source which releases short-lived alpha emitters. These disperse in the tumor by diffusion and by convection\, em itting their alpha particles at a therapeutically significant distance (a few mm) from the source. Specifically\, the parent isotope on the DαRT so urce is 224Ra (3.7 days half-life)\, which releases a sizable fraction of its progeny by its own alpha-decay induced recoil. 224Ra itself is being c ollected electrostatically onto the source after recoiling from a surface 228Th (1.9 years half-life) generator. An optimal method of producing such generators is through the collection of 228Fr\, which results in a practi cal\, longer lived 228Th generator fed by the intermediate isotope 228Ra ( 5.7 years half-life).\n\nhttp://indico.cern.ch/contributionDisplay.py?cont ribId=23&sessionId=24&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=23&sessionId=24 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Single particle states in 67Ni DTSTART;VALUE=DATE-TIME:20100607T094000Z DTEND;VALUE=DATE-TIME:20100607T100000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-28@cern.ch DESCRIPTION:Speakers: Mr. DIRIKEN\, Jan (Katholieke Universiteit Leuven)\n The interest in the structure of nuclei around 68Ni has been triggered lon g ago by the observation of the high excitation energy of the first 2+ in this nucleus [1]. Combining this observation with the fact that a minimum is reached in the systematic of B(E2\;2+ -> 0+)-values at N=40 in the neut ron rich nickel chain has lead to interpretations in terms of a harmonic o scillator subshell closure resulting in extensive theoretical studies [2] . The excitation spectrum of odd mass nuclei in the direct neighborhood of closed shells is usually governed by single particle excitations. One-neu tron transfer reactions are a useful tool to fix spins and parities of exc ited states and determine spectroscopic factors which can be compared to s hell model predictions. Recent large scale shell model calculations have s hown the sensitivity of certain nuclear parameters in this region to the s ize of the N=40 and N=50 shell gaps [3]. By measuring effective single-par ticle energies these shell gaps can be fixed in order to further update th e existing nuclear models.\nIn this case the excitation spectrum of 67Ni w as studied by performing the 66Ni(d\,p)67Ni reaction in inverse kinematics with an energy of 3 MeV/u at the REX-ISOLDE radioactive ion beam facility in CERN using the MINIBALL setup in combination with the T-REX particle d etection array [3]. The extracted angular distributions of the protons can be compared to DWBA calculations in order to determine spin and parity of the excited states as well as spectroscopic factors. Population of levels with excitation energy up to 6 MeV have been observed\, probably above N= 50.\nPreliminary results of the analysis will be presented. \n[1] R. Broda et al.

It consist s of the emission of a pair of protons from a nuclear ground state. Accord ing to the definition by V. Goldanskii who was the first to discuss this n ew type of radioactivity extensively\, one-proton radioactivity is not all owed to be an open decay channel for two-proton radioactivity (2p) candida tes.\n\nIn pioneering experiments at GANIL and GSI\, this new radioactivit y was discovered in 2002 and meanwhile 45Fe and 54Zn are established 2p em itters\, with a possible third nucleus\, 48Ni\, for which one event was mo st likely observed. These results allowed a detailed comparison with the t heoretical models available and showed that\, at the level of precision of the experimental data and of the predictive power of the models\, nice ag reement was obtained.\n\nThe latest step in the investigation of 2p radioa ctivity was the use of time-projection chambers to study the decay dynamic s via measurements of the individual proton energies and the relative prot on-proton emission angle. A first experiment at GANIL and a high-statistic s experiment performed at MSU on 45Fe allowed to gain first insides into the decay characteristics by comparison \nwith a three-body model. Meanwhi le\, 54Zn has also been studied with a TPC at GANIL.\n\nThe present talk w ill review the experimental results on ground-state two-proton radioactivi ty and compare these results with theoretical predictions.

The aim of this facility is to prov ide neutron rich isotope beams for both nuclear physics study (away from t he valley of stability) and developments dedicated to next generation faci lities such as SPIRAL2. The neutron rich isotopes are produced by photofis sion of 238U induced by the 50 MeV electrons from the linear accelerator. The isotopes coming out of the fission target effuse towards an ion source to form a beam that is analyzed through the on line separator PARRNe.

Unfortunately\, t heoretical predictions for superheavy nuclei differ considerably. In such a situation\, heavy nuclei of actinide region play a role of testing groun d for many theoretical approaches. Systematic study of these nuclei allows to put the error bars on theoretical description of the properties of sup erheavy nuclei. The present status of our understanding of heavy and super heavy nuclei within covariant density functional theory will be presented. I will concentrate on several aspects which define the shell structure an d the stability of superheavy nuclei\, such as (i) single-particle degrees of freedom\, (ii) role of pairing\, and (iii) the fission barriers.\n\nSi ngle-particle degrees of freedom define the shell structure. Thus\, the di fferences in model description of the single-particle energies are importa nt when extrapolating to superheavy nuclei. Following our initial analysis of the single-particle spectra in a few actinide nuclei [1]\, the systema tic analysis of \nthe accuracy of the description of the energies of defor med quasiparticle states has been carried out in relativistic Hartree-Bogo libov (RHB) approach in rare-earth and actinide regions [2] with the goal to better understand the accuracy of the extrapolation of single-particle energies to superheavy nuclei. Impact of particle-vibration coupling on th e single-particle structure of superheavy nuclei [3] will also be discusse d. Special attention will be paid to self-consistency \neffects [4].\n \nT he fission barriers play an important role in the physics of heavy and sup erheavy nuclei\; they are intimately connected with the existence and stab ility of superheavy nuclei. The role of treatment of pairing on the fissio n barriers has been investigated and new results were obtained [5]. The RH B and RMF+BCS calculations show that calculated fission barrier heights su bstantially depend on employed pairing force and treatment of pairing wind ow even in the case when the pairing strengths are adjusted to the same va lue of the pairing gap at the ground state. The consequences of a differen t treatment of pairing for the stability of superheavy nuclei will be disc ussed. In addition\, we performed systematic study of the impact of triaxi ality on the fission barrier height [6]\; in many cases it substantially d ecreases the fission barrier.\n\nThis work has been supported by the U.S. Department of Energy under the grant DE-FG02-07ER41459\n\n[1] A.V.Afanasje v\, T.L.Khoo\, S.Frauendorf\, G.A.Lalazissis\, and I.Ahmad\, Phys.

For example\, the beta- asymmetry parameter A for pure Gamov-Teller nuclear decays is sensitive to a possible tensor component in the weak interaction if determined at the 1 % precision level. Here we will present two measurements of this paramet er. Our results are competitive with the best results available in literat ure and contain information on tensor type charged weak currents.\n The lo w temperature nuclear orientation technique is used to create a polarized ensemble of radioactive nuclei by cooling them down to a few millikelvin i n a strong magnetic field that is created either by hyperfine interactions or by an external magnet. The beta-particles are observed by semiconducto r detectors operating at a temperature of about 10 K and facing directly t o the sample. In previous measurements the accuracy of such an experiment was usually limited to several percent by the scattering of beta particle s and the deflection of their trajectories by the magnetic field. We have developed a method based on GEANT4 Monte-Carlo simulations to gain control over these effects. The code was extensively tested by comparing simulati ons to experimental data taken under various well-controlled experimental conditions 2).\nFirst results were obtained with the isotopes 114In and 60 Co with a precision at the 1\,5 % level\; which is better then the current literature values 3). An extensive study of the recoil corrections on the Standard Model prediction value was done to interpret our results in term s of exotic currents.\nThe method is further being improved to push the pr ecision and new data is under analysis. Our goal is to reach the 1% level or better\, which would improve the sensitivity to tensor type weak curren ts by a factor of 2 to 3 compared to previous experiments in beta decay.\n \n1) N.

In particular\, we will discuss the Isospin Equilibration Dynamics. At low energies this manifests via the recently observed Dynamic al Dipole Radiation\, due to a collective neutron-proton oscillation with the symmetry term acting as a restoring force. \nAt higher beam energies I so-EoS effects will manifest through isospin diffusion between projectile and target and Imbalance Ratio Measurements\, in particular in correlation with the total kinetic energy loss. \nAt higher beam energies (above 100 Mev/u) suitable observables\, such as the isotopic content of particle and meson emission and collective flows\, allow one to test the Iso-EoS at hi gh density.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=51&s essionId=21&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=51&sessionId=21 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:A novel method for isomeric beam production DTSTART;VALUE=DATE-TIME:20100608T080000Z DTEND;VALUE=DATE-TIME:20100608T082000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-53@cern.ch DESCRIPTION:Speakers: Dr. FLANAGAN\, Kieran (The University of Manchester) \nWe report a new innovation in laser spectroscopy: Collinear Resonant Ion ization Spectroscopy (CRIS)\, which aims to study the rarest isotopes prod uced at ISOLDE.

These half lives are particularly needed for r-process calculation s as an essential test to validate the nuclear and beta-decay models away from stability[3].\n\nIn this talk results from a recent RISING experiment aiming at studying neutron-rich lead isotopes with A>210 will be reported .\nThe experiment employed the active stopper configuration of the RISING array in order to study both isomeric gamma decay of long-lived states and the beta decay of heavy lead and bismuth isotopes.\n\nThe nuclei of inter est were populated by relativistic fragmentation of 238U at 1GeV/u on a Be target. The ions of interest where transported in the GSI FRS separator [ 4] and implanted in an active catcher consisting of 9 Silicon DSSSD. The g amma decay after implantation was measured by the 15 Cluster HPGe detector s of the RISING array [5\,6]. \n\nNew isomers have been identified in the populated Pb\, Bi and Tl isotopes\, and their lifetime and isomeric ratio s are being evaluated. Comparison with shell model calculations will be pr esented.\n\n[1]M. Pfutzner et al.\, Phys. Lett. B 444 (1998) 32-37.\n[2]Zs . Podolyak\, Acta Physica Polonica B36 (2005) 1269.\n[3]I.N. Borzov.

This al lows one to study the properties of extremely weakly bound or even unbound nuclei which spontaneously emit protons or neutrons. These nuclei have a huge imbalance in the proton/neutron ratio\, adding a new degree of freedo m - the isospin - and opening a large field of new experimental possibilit ies.\n\nIt has been observed that\, in these systems\, nuclear forces mani fest themselves in different ways. This is interpreted presently as an iso spin dependence\, and is questioning our understanding of the behaviour of nuclear matter going from proton- rich to neutron-rich matter.\n\nThe lig ht part of the nuclide chart offers a unique scenario where particle-bound and unbound nuclei mixed in the same isotopic chain\, offering the possib ility to follow how the structure develops as a function of increasing neu tron number. In general\, the isospin variations present in exotic nuclei are predicted to modify the nuclear mean-field picture together with the l ong and short-range correlation and are thus a key issue for the understan ding of the evolution of the shell structure with isospin.\n\nWe will revi ew in this talk a personal selection of recent experimental results obtain ed in different laboratories during the last years. The enormous quality a nd amount of data\, are a clear sign of the dynamism and interest awaken b y the investigation of nuclear species close to the dripline.\n\nhttp://in dico.cern.ch/contributionDisplay.py?contribId=114&sessionId=11&confId=6131 0 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=114&sessionId=1 1&confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Exploring life-time of low-lying states in neutron rich nuclei tow ards 78Ni with the plunger technique at GANIL DTSTART;VALUE=DATE-TIME:20100607T102000Z DTEND;VALUE=DATE-TIME:20100607T104000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-88@cern.ch DESCRIPTION:Speakers: MOUGINOT\, Batipste (Institut de Physique Nucléaire d'Orsay)\nOne of the most critical ingredients in determining the disappe arance or appearance of magicity in nuclei far from stability is the evolu tion of single-particle energies with increasing neutron or proton numbers when moving away from the valley of stability. The three known cases of d isappearance of shell effects at N=8\, 20 and 28 in neutron rich nuclei ar e understood as due to the effect of the tensor part of the nucleon-nucleo n interaction. The tensor force is held responsible for the strong attract ion between a proton and a neutron in spin-flip partner orbits. A recent g eneralization of such mechanism foresees a similar behaviour also for orbi tals with non-identical orbital angular momenta. It is expected that orbit als with anti-parallel angular momenta attract each other and orbitals wit h parallel angular momenta repulse each other. The change in shell structu res based on this mechanism has recently been discussed for different mass regions of the nuclear chart. \n\nIn this context neutron-rich nuclei clo se to shell gaps are particularly interesting since they allow to search f or anomalies when compared with shell-model predictions. It is predicted\, for example\, that the Z=28 gap for protons in the pf-shell becomes small er when moving from 68Ni to 78Ni as a consequence of the attraction betwee n the proton f5/2 and neutron g9/2 orbits and the repulsion between the pr oton f7/2 and the neutron g9/2 states. The same argument would also predic t a weakening of the N=50 shell gap when depleting the proton f5/2 state u pon approaching the 78Ni nucleus\, due to the diminished attraction betwee n the neutron g9/2 and the proton f5/2 orbits and the reduced repulsion be tween the neutron g7/2 and the proton f5/2 states. \n\nRecently an experi ment aiming at the study of the evolution of the structure of neutron rich Cu and Zn isotopes has been performed. This experiment uses the plunger t echnique in order to measure life time of gamma transition involved in the decay of excited states in these exotic nuclei. The studied nuclei have b een populated using reactions induced by a cocktail beam composed of 73\,7 4Zn RIB’s of 34MeV/u in a CD2 target. The cocktail beam is produced by t he in-flight technique using the first half of the LISE separator. The sec ond half is used for the selection and identification of the final product s after interaction in the secondary CD2 target. The EXOGAM array and the differential Plunger technique provide information on the in-beam gamma sp ectroscopy and life time of the excited states in the picoseconds to tens of picoseconds \n\nThe first results obtained on the life time of excited states in 72\,73\,74Zn will be reported together with the comparison to re sults from Coulomb excitation experiment at REX-ISOLDE. A picture of the l ow-energy structure in these isotopes towards the middle of the g9/2 or bital will be given via: i) identification of the levels populated with in elastic scattering reaction and ii) determination\, in a model-independent way\, of the transition probabilities of those levels towards the ground state.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=88&sessio nId=6&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=88&sessionId=6& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Trends of FEE instrumentations for Spiral2 detectors DTSTART;VALUE=DATE-TIME:20100608T161000Z DTEND;VALUE=DATE-TIME:20100608T163000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-116@cern.ch DESCRIPTION:Speakers: TRIPON\, Michel (GANIL)\nAlong with the implementati on of SPIRAL2 \, the second generation of RIB accelerator of the GANIL lab oratory \, have emerged projects of new detectors and instrumentations whi ch comply with new constraints brought by high intensities RIB\, such as h igher counting rates\, higher number of channels\, higher data readout rat e\, fast link connections between DAQ instrumentations\, experimental cave accessibility. European and French laboratories have collaboration in nin e projects of new instrumentations for the future SPIRAL2 detectors: Exoga m2\, DESIR\, ACTAR\, PARIS\, AGATA\, FAZIA\, GASPARD\, S3\, and NEDA.\nRep resentatives of these detectors instrumentations have met within the Elect ronic Group of the Instrumentation Coordination Committee (ICCEG) for the SPIRAL2 detectors. The ICCEG aims to find synergies in hardware\, firmware and embedded software fields in order to share and to retrieve developmen ts undertaken for these instruments\, as well as to exchange knowledge on systems and technologies. Templates of specifications of these detectors a nd their respective instrumentations show a wide range of specifications: kinds of detectors (HPGe\, Si\, scintillators\, and gas)\, number of chann els (from 100 to 20000)\, counting rate (from 1 kHz to 300 kHz)\, total da ta rate (from 1Mb/s to 1 Gb/s)\, number of trigger levels (from triggerles s to 2). Among the nine SPIRAL2 detector instrumentation projects\, four p rojects are either in the demonstration phase (AGATA)\, either in early de velopment phase (Exogam2\, ACTAR\, FAZIA). It is worth to notice:\n- Two i nstrumentation architectures are emerging: one based on the implementation of analog asics which integrate filters and sampling memories (ACTAR) and one based on the implementation of flash ADC associated to digital proces sing.\n- Fast serial communication protocols such as Gigabits Ethernet\, P CIe and Eurora using copper or optical media are widely deployed\; these l inks are managed in embedded software FPGA.\n- The choice of the electroni c standard is widely opened: customized racks\, NIM\, ATCA\, μTCA. Nevert heless\, digital modules are mainly designed in the ATCA and μTCA standar ds due to their resources in high speed communication and in high frequenc ies bandwidth signals transmissions.\n- A system which provides a referenc e clock (200MHz)\, time stamps parameters and returns trigger decisions is required.\nGANIL is involved in two projects. In the ACTAR one\, GANIL ha s taken in charge the development of the trigger and local clock distribut ion system\, so called MUTANT and BEM\; both modules are in μTCA standard . In the Exogam2 project\, GANIL manages the collaboration of several labs for the design and the implementation of the instrumentation. Its archite cture is based on the AGATA instrumentation one\; it retrieves the GTS sys tem but not the complex ATCA standard. The digitizer is the key developmen t. Synergies with NEDA\, PARIS\, and S3 have been pointed out during ICCEG and last SPIRAL2 week meetings. Thanks to the FADC mezzanines concept and the firmware flexibility\, the EXOGAM2 digitizer will be made versatile e nough for dealing with the different frequency bandwidth analog inputs and for running specific digital processing.\nWhen coupling several detectors \, the critical issue is how compliant are their instrumentations. The ICC EG had a meeting about what systems for clock distribution\, time stamping and trigger. Three systems were examined: the TDR running at Jyvaskyla\, the GTS implemented in AGATA and the BUTIS and White Rabbit under developm ent at GSI. The GTS has been found a comprehensive system\, having a possi ble connection to BUTIS. GANIL suggests deploying the GTS system in NIM fo rm for the GTS fanin fanout levels and in μTCA form for the trigger proce ssor level. Thanks to the μTCA resources\, high speed signals and high le vel messages could be exchanged between various instrumentations and DAQ o f detectors involved in an experiment.\n\nhttp://indico.cern.ch/contributi onDisplay.py?contribId=116&sessionId=17&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=116&sessionId=1 7&confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Front-end electronics and Controls as seen from the NUSTAR/FAIR pe rspective DTSTART;VALUE=DATE-TIME:20100608T152000Z DTEND;VALUE=DATE-TIME:20100608T154000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-111@cern.ch DESCRIPTION:Speakers: SIMON\, Haik ()\nThe experimental program at FAIR re quires a smooth transition from existing experiments as well as integratin g a variety of old and new detector systems from different collaborations world-wide.

Using projectile fragmentation on a graphi te target and ionization in an ECR ion source via a cold transfer passage\ , mostly isotopes of gases lighter than Xe and fragments of volatile molec ules such as O and F were post-accelerated. During the past year\, a proje ct was formed to upgrade the present facility with a 1+ to n+ charge breed ing system\, thus permitting the use of more versatile 1+ sources for exte nding the range of elements available for post-acceleration. Numerous phys ics projects based on the potential new capabilities of SPIRAL 1 were rece ntly formulated in the form of letter of intents\, attesting of the scient ific relevance of such upgrade. \nThis contribution will present the statu s of the upgrade\, its positioning with respect to the SPIRAL 2 production capabilities and physics objectives.\n\nhttp://indico.cern.ch/contributio nDisplay.py?contribId=82&sessionId=19&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=82&sessionId=19 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:HIE-ISOLDE: Status Report of the Project and Highlights DTSTART;VALUE=DATE-TIME:20100609T073000Z DTEND;VALUE=DATE-TIME:20100609T080000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-80@cern.ch DESCRIPTION:Speakers: KADI\, Yacine (CERN)\nThe research with radioactive beams has strengthen the link between technical developments and physics o utput. The study of radioactive beams allows us to follow the evolution of nuclear structure over extended regions in the nuclear chart. ISOLDE has nowadays a vast variety of species produced\, more than 1000 nuclei from a lmost 70 elements\, the largest number by far of the existing ISOL-facilit ies. A key feature of the REX-ISOLDE complex is that essentially all isoto pes produced can be charge bred and accelerated further up to 3 MeV/u. The present energy range limits the experimental program to Coulomb excitatio n of light and intermediate mass nuclei and to transfer reaction for the l ightest species.\n\nThe ISOLDE facility has been expanded several times in order to continue being a reference facility. Improvement of beam quality \, increase in intensity and availability of new radioactive beams will bo ost decay experiments as well as the study of ground state properties as\, for instance\, Penning trap mass measurements that continuously refine ou r understanding of the nuclear mass surface. An energy upgrade will make a ll produce nuclei available for reactions up to and above the Coulomb barr ier opening new avenues from the physics point of view. The enlarged dynam ic range\, first to 5.5 MeV/u and in a later stage to 10 MeV/u\, will allo w the optimization in each case with respect to cross section and reaction channel opening. \n\nA major upgrade of the present facility\, High Inten sity and Energy ISOLDE (HIE-ISOLDE)\, is now approved to fully exploit the latest developments and significantly increase the ISOLDE scope. The HIE- ISOLDE project proposes a staged upgrade in three main categories: beam in tensity\, beam energy and beam quality. In this talk the present status of the project\, and the future plans will be presented.\n\nhttp://indico.ce rn.ch/contributionDisplay.py?contribId=80&sessionId=14&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=80&sessionId=14 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:beta-decay half lives of nuclei approaching the r-process path nea r the 126-neutron shell closure DTSTART;VALUE=DATE-TIME:20100608T102000Z DTEND;VALUE=DATE-TIME:20100608T104000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-81@cern.ch DESCRIPTION:Speakers: Ms. MORALES LÓPEZ\, Anabel (USC)\nThe decay propert ies of neutron-rich nuclei around N=126 are very important not only becaus e they will provide valuable information about nuclear models far from sta bility\, but also because these nuclei approach the astrophysical rapid-ne utron capture [1] path near the waiting-point A~195. Particularly\, the be ta-decay half lives provide a noteworthy understanding of the r-process t ime-scales\, and hence of the atomic abundances in the Universe. The use o f projectile fragmentation at relativistic energies has opened up the poss ibility to produce these nuclei via the “cold-fragmentation” reaction channels [2]. Isomer spectroscopy using passive stoppers with a germanium array [3] and time correlations for beta-decays with an active stopper [4 \,5] have provide the first structural information on some of them. \n In a previous experiment the half-lives of 198-199-200Ir\, 199-200Os and 194-195Re were measured from time-position correlations between implanted ions and subsequent beta-decays using double side silicon strip detectors (DSSSD) [4]. In this work we benefit from the last developments using bet a-delayed gamma-ray spectroscopy to measure the beta-decay half lives of o ther nuclei at the current limits of experimental synthesis. The present e xperiment was performed at GSI where the Fragment Separator (FRS) was used to identify and select heavy neutron-rich nuclei produced in the reaction 208Pb+Be at 1 AGeV. The nuclei were then slowed down and implanted in thr ee DSSSD detectors acting as active stopper [6]\, recording the position a nd time of implantations and decays. Additionally\, the RISING gamma-ray array [7] enclosed the active stopper in order to register the characteris tic transitions from daughter nuclei. The event-by-event position and time correlations between implantations and gamma-labelled radioactive electro ns allowed for the measurement of the beta-decay half lives of 204Au\, 204 -203Pt and 200-202Ir with improved background conditions.\n The new me asurements allow to validate the numerical technique previously proposed f or the analysis of beta-decay half lives under complex background conditio ns [4]\, and confirm the conclusions on the beta-decay of nuclei in this r egion of the Segrè chart. Indeed\, the comparison of all our measurements with theoretical predictions [8\,9] indicates the importance of FF transi tions in the beta-process picture of this region. Moreover\, the fact that beta-decay models used in standard r-process calculations do not consider FF transitions suggests that the r-process matter flow across N=126 is fa ster than expected. \n \n[1] E.M.

(SCK-CEN))\nSince 1995\, SCK•CEN has been studying the coupling of a proton accelerator\, a windowless liquid Lead-Bismuth spallation target an d a Lead-Bismuth cooled\, sub-critical fast core. The study was first perf ormed in collaboration with Ion Beam Applications (IBA\, Louvain-la-Neuve) in the frame of the ADONIS project (1995-1997). ADONIS was a small irradi ation facility\, based on the ADS concept\, having a dedicated objective t o produce radioisotopes for medical purposes and more particularly 99Mo as a fission product from highly enriched 235U fissile targets. The ad-hoc s cientific advisory committee recommended extending the purpose of the ADON IS machine to become a Material Testing Reactor (MTR) for material and fue l research\, to study the feasibility of transmutation of the minor actini des and to demonstrate at a reasonable power scale the principle of the AD S. The project\, since 1998 named MYRRHA\, has then evolved to a larger in stallation.\n\nMYRRHA today is conceived as a flexible fast spectrum irrad iation facility\, able to work as an Accelerator Driven System (subcritica l mode) and in critical mode. In this way\, MYRRHA will allow fuel develop ments for innovative reactor systems\, material developments for GEN IV sy stems\, material developments for fusion reactors\, radioisotope productio n for medical and industrial applications and industrial applications\, su ch as Si-doping. MYRRHA will also demonstrate the ADS full concept by coup ling the three components (accelerator\, spallation target and subcritical reactor) at a reasonable power level to allow operation feedback\, scalab le to an industrial demonstrator and allow the study of efficient transmut ation of high-level nuclear waste.\n\nMYRRHA consists of a proton accelera tor with a proton energy of 600 MeV and a design intensity of 4 mA\, coupl ed to a liquid Lead-Bismuth Eutectic spallation neutron source. Apart from the experimental and irradiation possibilities in the subcritical reactor \, the MYRRHA proton accelerator on its own can be used as a supply of pro ton beams for a number of experiments. In order to explore new research op portunities offered by the accelerator\, a pre-study was initiated within the framework of the “Belgian Research Initiative on eXotic nuclei” (B riX) network of the Interuniversity Attraction Poles Programme of the Belg ian State. This study is investigating unique possibilities for fundamenta l research using high-intensity proton beams with a fraction of the full b eam during ADS operation (up to 200 µA). An interesting approach for fund amental research using the 600-MeV proton accelerator is the installation of an Isotope Separator On-Line (ISOL@MYRRHA) facility with a ruggedized t arget-ion source system\, which is able to provide intense low-energy Radi oactive Ion Beams (RIB) for experiments requiring very long beam times (up to several months). This will open unique opportunities for RIB research in various scientific fields\, which is complementary with the activities at other existing and future facilities. In a second phase\, when the MYRR HA reactor will run as a stand-alone critical reactor\, the full proton-be am intensity might be used for ISOL@MYRRHA or other applications.\n\nMYRRH A is foreseen to be in full operation by 2024 and it will be operated in t he first years as an ADS.\n\nhttp://indico.cern.ch/contributionDisplay.py? contribId=85&sessionId=19&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=85&sessionId=19 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Introduction to Laser Spectroscopy at the TRIGA-SPEC Facility DTSTART;VALUE=DATE-TIME:20100610T162500Z DTEND;VALUE=DATE-TIME:20100610T164000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-3@cern.ch DESCRIPTION:Speakers: Dr. GEPPERT\, Christopher (Universität Mainz)\nOn-l ine laser spectroscopy allows us to study the nuclear ground-state propert ies of short-lived exotic isotopes by measuring their hyperfine structure and isotope shifts. The properties that can be extracted from this are the nuclear spin\, the magnetic moment\, the spectroscopic nuclear quadrupole moment\, and the change in the mean-square nuclear charge radii between i sotopes. Experimental data can be determined with high precision and the n uclear parameters can be extracted in a nuclear-model free way. Collinear laser spectroscopy has played an important role in obtaining hyperfine str uctures and isotope shifts of short-lived isotopes and is still a versatil e tool for the exploration of long isotopic chains reaching far from the v alley of nuclear stability.\nAt the TRIGA research reactor at the Universi ty of Mainz a collinear laser spectroscopy experiment is currently being i nstalled\, which will allow us to study short-lived fission products creat ed by neutron induced fission of\, e.g.\, 249Cf near the reactor core. A g as-jet transport system will be employed to guide the nuclei from the prod uction site close to the nuclear reactor core to an ECR ion source\, where ion beams of a large variety of elements including refractory elements wi ll then be produced and after mass separation be guided to the TRIGA-Laser experiment.

Since the end of the EUROBALL deployment\, very sp ecialized large arrays as well as compact arrays optimized for the first g eneration of radioactive ion beam (RIB) facilities\, have been extensively used by the Nuclear Physics community. Examples of former arrays are JURO GAM [1] and JUROGAM II coupled to RITU at JYFL\, CLARA [2] coupled to PRI SMA at INFN-LNL and RISING [3] installed at the focal plane of the Fragmen t Separator at GSI\, while examples of the latter are EXOGAM [4]\, inst alled at GANIL and MINIBALL [5] at REX-ISOLDE.\nPresently\, Nuclear Physi cs is entering a new era with the construction of second generation RIB fa cilities as the in-flight FAIR-NUSTAR and the ISOL SPIRAL2 and SPES.

Carlsson\, M. Kortelainen\, N. Michel\, A. Pastore\, F. Raimondi\, J. Toivanen\, P. Toivanen\, and P. Veselý\nRe liable predictions of nuclear properties in exotic nuclei\, with controlle d theoretical errors\, are essential for modelling many stellar processes. In medium heavy and heavy nuclei\, the only available approach\, able to provide global information on ground-state properties\, is based on the on e-body degrees of freedom\, which in modern formulation takes the form of the energy density functional (EDF) theory. Over the years\, methods based on such ideas have proved to be extremely efficient\, however\, the prese nt-day status thereof is far from being complete. Two elements of the appr oach are currently intensely studied\, namely\, construction of schemes th at would allow for systematic improvements of the precision and determinat ion of theoretical errors and variances.\nIn Ref. [1]\, it was proposed to shift attention and focus of the EDF methods from ground-state bulk prope rties (e.g. total nuclear masses) to single-particle (s.p.) properties\, a nd to look for a spectroscopic-quality EDFs that would correctly describe nuclear shell structure. Proper positions of s.p. levels are instrumental for good description of deformation\, pairing\, particle-core coupling\, a nd rotational effects\, and many other phenomena. Up to now\, methods base d on using EDFs\, in any of its variants like local Skyrme\, non-local Gog ny\, or relativistic-mean-field [2] approach\, were mostly using adjustmen ts to bulk nuclear properties. As a result\, shell properties were describ ed poorly. After so many years of investigations\, a further increase in p recision and predictability of all methods based on the EDFs may require e xtensions beyond forms currently in use [3\,4]. Before this can be fully a chieved\, it was proposed to first take care of the s.p. properties\, and come back to precise adjustment of bulk properties once these extensions a re implemented.\nWithin the standard 12-parameter form of the Skyrme funct ional [2]\, an improvement of spectroscopic properties cannot be obtained [3]\, and extensions of this form seem to be mandatory. One possible way c ould be the inclusion of density dependence into all the 12 coupling const ant of the standard functional [5]. Another one\, which was recently propo sed in Ref. [4]\, aims at including gradient corrections up to next-to-nex t-to-next-to-leading order (N3LO -- sixth order).

The fu sion of complex (composite) nuclei is governed by a delicate balance betwe en the attractive nuclear and repulsive Coulomb interactions. Detailed exp eriments made in the last three decades have shown that the fusion process cannot be understood as a simple barrier penetration by a structureless o bject with a potential depending only on the distance between the centers of the colliding systems. The associated tunneling probability was shown t o be extremely sensitive to the plasticity of the intrinsic structure that can evolve during the process and to the interplay of the many open and v irtual channels\, whose amplitudes may be tuned by varying the beam energy and/or choosing different projectile-target combinations. Thus the theore tical tool to conceptually understand the modification of barrier(s) towar ds fusion due the coupling of direct reactions to the elastic channel is a coupled channel approach. To obtain a complete understanding of fusion pr ocess necessitates also the investigation of the associated direct channel s.\nShort-lived Radioactive Ion Beams (RIB) with weak binding\, unusual ne utron/proton asymmetry and extended spatial distributions (halos) provide a new vista to probe such a multidimensional tunneling. The experimental c onditions for measuring the fusion cross sections using low intensity RIB combined with the need to identify a complete amalgamation of project and target (complete fusion) made these measurements challenging. The role of exotic structures on the tunneling process and its interconnectivity with other open channels especially coupling to unbound states (breakup) and tr ansfer channels have been pursued mainly using beams of 6\,8He\, 9Li\, 11B e. Such studies have focused mainly on light ion beams as they show a larg e variety of exotic structures as compared to heavier nuclei. The coupling to states in the continuum in such nuclei is also being used to study ope n quantum systems and the effect of dechorence to describe nuclear reactio ns. Studies of the tunneling of composite objects are also of fundamental interest in molecular processes and transport in nanodevices\nIn this talk after a brief historical overview of the major stepping stones of fusion with stable beams\, we will review the recent status of the field and our present understanding of fusion with radioactive ion beams and discuss per spectives in this field.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=106&sessionId=20&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=106&sessionId=2 0&confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Experiments with Exotic Nuclei applying a new Generation on In-Fli ght Separators and Spectrometers DTSTART;VALUE=DATE-TIME:20100607T150500Z DTEND;VALUE=DATE-TIME:20100607T153000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-107@cern.ch DESCRIPTION:Speakers: Prof. GEISSEL\, Hans (GSI Darmstadt Germany /Justus- Liebig Universität\, Giessen)\nThe research potential with exotic nuclei is determined by fast\, sensitive and highly efficient separation and high -resolution detection methods.

This experiment was possible thanks to the availability of the selective Resonance Ionization Laser Ion Source. In the ten years since then\, much structural informati on has been obtained on radioactive neutron rich isotopes in this region. In this contribution a short summary will be given of recent discoveries s outh of 68Ni. \n\nNow\, 10 years later\, a beta decay experiment was perfo rmed at ISOLDE on 60-68Mn with the LISOL tape station. Some of the high qu ality spectra will be shown and first results will be presented. A compari son will be made with recently obtained spectra from in-flight facilities. \n\nIt will be shown that online a factor ten increase in yield could be achieved by further optimizing the laser ionization scheme of the neutron rich Mn isotopes with A>=65.\n\nThe A=62 and 63 Mn beams were also post-ac celerated at REX-ISOLDE and Coulomb excitation has been induced on 62\,63M n and 62Fe at the MINIBALL setup.

The fusion probability is largely affected by two main features\, the extended \ndensity distribution and the weak binding energy of these exotic system s. In addition to this\, one and two neutron \ntransfer can also play an important role in the dynamics of the fusion process. Sub-barrier fusion of 6He was studied \nin [1\, 2\, 3] but no clear signature of fusion enha ncement was found. This picture is consistent with the observation of \nl arge yields of alpha particles [4] which could be attributed only to neut ron transfer (incomplete fusion) and projectile \nbreakup. However in a r ecent measurement [5]\, a large enhancement of the fusion channel was obs erved in the \nscattering of 6He+206Pb at deep sub-barrier energies. The a uthors explained their finding using a sequential neutron\ntransfer mecha nism [6] that increases the fusion probability and is able to reproduces t he data. To clarify the situation \nwe have performed a new measurement o f the fusion cross-sections for the system 6He + 206Pb\, in the range of e nergies \n14-18 MeV (Lab) using the target activation technique. The expe riment was performed at the RIB facility of the Cyclotron \nResearch Cent er (UCL) at Louvain-la Neuve (Belgium). The irradiated targets were analyz ed in the Detector Laboratory at \nthe University of Huelva (Spain). The d etails of the experimental method and the new fusion data will be presente d and \ndiscussed.\n\nReferences\n\n[1] N. Keeley\, R. Raabe\, N. Alamanos and J.L.

Anomalous ground state spins have been measured for A=73 and A =81\, and these\, together with the moments\, are compared with theoretica l calculations.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId= 35&sessionId=6&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=35&sessionId=6& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:In-gas-cell laser spectroscopy of neutron-deficient 57-59Cu isotop es at LISOL DTSTART;VALUE=DATE-TIME:20100611T094000Z DTEND;VALUE=DATE-TIME:20100611T100000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-61@cern.ch DESCRIPTION:Speakers: Dr. THOMAS ELIAS\, Cocolios (Instituut voor Kern- en Stralingsfysica)\nWith a single proton outside the Z=28 shell closure and spanning the nuclear chart across several magic or quasi-magic neutron sh ells (N=20\,28\,40\,50)\, the copper isotopes are ideal to study the evolu tion of magicity. Of particular interest is the isotope 57Cu with a single proton outside the controversial doubly-magic\, N=Z=28\, nucleus 56Ni. Th e earlier measurement of the magnetic moment of 57Cu by beta-NMR pointed t owards a large breaking of the 56Ni core but attempts to confirm this meas urement with the in-source laser spectroscopy technique at a hot-target IS OL facility has been unsuccessful.\n\nIn a recent campaign\, in-gas-cell l aser ionization spectroscopy coupled to mass separation and nuclear decay identification has been performed for the first time at the LISOL facility (Belgium). The magnetic dipole moments of 58-59Cu was confirmed but that of 57Cu shows a large discrepancy from the published value. The new propos ed value is in good agreement with empirical and theoretical predictions\, supporting the magic nature of the 56Ni core in the ground state of 57Cu. The g-factor of the odd-odd 58Cu isotope is compared to empirical g-facto rs and points similarly to a configuration consistent with a magic 56Ni co re.\n\nThe success of this measurement opens also new possibilities for fu ture gas-catcher facilities such as S3 at GANIL.\n\nhttp://indico.cern.ch/ contributionDisplay.py?contribId=61&sessionId=25&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=61&sessionId=25 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:DYNAMICAL DIPOLE MODE IN FUSION HEAVY-ION REACTIONS DTSTART;VALUE=DATE-TIME:20100610T155000Z DTEND;VALUE=DATE-TIME:20100610T161000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-64@cern.ch DESCRIPTION:Speakers: Dr. SILVESTRI\, Rosetta (Universita degli Studi diNa poli "Federico II" -Universita & INFN\, Napoli)\nAn experimental overview [1-6] on an interesting feature of dipole excitation in heavy-ion collisio ns\, the dynamical dipole mode\, predicted to occur between interacting io ns with a large charge asymmetry will be presented. In a campaign of exper iments where the same compound nucleus in the 132Ce region was probed thro ugh different charge asymmetry entrance channels\, a larger gamma-ray emis sion from the more charge asymmetric channel was evidenced\, in the Giant Dipole Resonance energy range. The beam energy dependence of this extra ga mma yield was extracted by comparing the results obtained at different bea m energies [2-5]. The first angular distribution data taken at Elab= 16 Me V/nucleon support its prompt dynamical nature [2\,3]. Our data [2-5] are c ompared with theoretical calculations performed within a BNV transport mod el and based on a collective bremsstrahlung analysis of the entrance chann el reaction dynamics [7] and with recent data [6] obtained for compound n uclei in the same mass region but formed through smaller entrance channel charge asymmetry.\n\nUsing the prompt dipole radiation as a probe and empl oying radioactive beams\, new possibilities for the investigation of the s ymmetry energy at sub-saturation density are foreseen and will be discusse d [5].\n\nAs a fast cooling mechanism on the fusion path\, the prompt dipo le radiation could be of interest for the synthesis of superheavy elements through hot fusion reactions. The entrance channel charge asymmetry could provide a way to cool down the hot fusion paths\, so ending up with a lar ger survival probability. To shed light in this direction and to study if pre-equilibrium effects survive in heavier systems\, we extended our study to the 192Pb compound nucleus\, formed at an excitation energy of 232 MeV \, by using the 40Ca + 152Sm and 48Ca +144Sm reactions at Elab= 440 MeV a nd 485 MeV\, respectively. Preliminary results of this measurement\, done with the aim to search for the dynamical dipole mode in both fusion-evapor ation and fusion-fission events for the first time in this mass region\, w ill be presented.\n\nReferences\n[1] S.

(Institut für Kernphysik\, Universität zu Köln\, D-50937 Köln\, Germany /Gesselschaft für Schwerionenforschung (GSI)\, D-64291 Darmstadt\, Germany)\nThe isomeric decays in 127Cd and 12 5Cd having two proton holes and three and five neutron holes respectively in the doubly magic 132Sn core have been studied. To date even mass heavy Cd isotopes have been investigated in detail [1\,2]. The obtained sytemat ics exhibits evolution of single particle energies and addresses the ons et of deformation when removing particles from the core nucleus. The exper iment was performed at GSI\, Darmstadt to investigate the structure of exc ited states in odd mass neutron rich Cd isotopes. Isomeric decays in the n uclei of interest were observed in the fragmentation reaction of a 136Xe b eam at energy 750MeV/u on a 9Be target of 4g/cm2 thickness. The Cd ions were selected using the standard Bρ-ΔE-Bρ method in the FRagment Separa tor (FRS). Event by event identification of the particles in terms of thei r mass A and charge Z was provided by the standard FRS detectors. Isomers populated in the reaction were implanted in a plastic catcher surrounded b y 15 Ge cluster detectors from RISING array [3] to detect the γ decays. In 127Cd \, excited states with pure neutron ν (h11/2 -2 d3/2 -1) charact er analogous to 129Sn have been observed\, whereas in 125Cd apart from the previously observed (19/2)+ isomer reported in Ref. [4]\, a new isomeric state has been detected . The level schemes of these nuclei have been e stablished based on the obtained intensity balance and life time informati on. The new experimental information provides vital input for the shell mo del description of the evolution of neutron hole energies in neutron-rich nuclei in the N=82\, Z=50 region.

The wealth of experimental data on this subject co vers in most cases an interval of temperatures up to 2.5 MeV and is mainly based on the study of the GDR gamma-decay from fusion-evaporation reactio ns. These data have been shown to provide an important testing ground for the theoretical models. In particular\, the change of the GDR width with a ngular momentum and temperature reflects the role played by quantal and th ermal fluctuations in the damping of the giant vibrations.\nCertain nuclei are expected to exhibit very exotic behavior – the Jacobi shape transit ion. This phenomenon is predicted as an abrupt change from an oblate shape at the so called critical value of spin to triaxial and to more elongated shapes\, and finally undergoes scission. \nFirst results from the experim ent performed in LNL Legnaro aiming at investigating the spin and tempera ture evolution of the 88Mo nucleus as well as the GDR width at high temper ature will be presented. The 48Ti beam at 300\, 450 and 600 MeV bombarded 40Ca target producing 88Mo compound nucleus at temperatures 3\, 3.8 and 4. 5 MeV respectively.

Masses and binding energies are integral quantities reflecting all nucleonic interactions. H owever\, various differences and double differences of binding energies ca n isolate particular physics or specific interactions. There has been enor mous progress in mass measurements in recent years\, in particular with Pe nning traps and storage rings. This has spawned significant advances in un derstanding the relationship between masses and structure and\, thereby\, using measured masses to study structural evolution in nuclei\, underlying shell structure\, the development of collectivity\, quantum phase transit ions\, and the microscopic interactions that drive this evolution. This ta lk will focus on a few of these recent developments\, in particular using two nucleon separation energies and proton-neutron interaction strengths d educed from nuclear masses.

However\, 32 so-called p-nuclei are thought to be pr oduced in the p process\, where proton-rich nuclei are made by sequences o f photodisintegrations and (p\,g) reactions and following decays on existi ng r- and s-seed nuclei. \n\nCharged-particle induced cross section measur ements in the astrophysically interesting energy range are already very ch allenging on stable nuclei. Only a minute part of the nuclei involved in p -process networks\, however\, is stable. The most promising approach to de termine the desired reaction rates is to produce the isotopes in Radioacti ve Ion Beam facilities and to investigate the reactions in inverse kinemat ics. A pioneering experiment was recently performed at the Experimental St orage Ring (ESR) at GSI. Fully stripped ions of 96Ru were injected into th e storage ring and slowed down to a few MeV/nucleon. The reaction products were detected with different particle detectors.\n\nSimilarly photon-indu ced cross sections on radioactive nuclei can be measured in inverse kinema tics applying the Coulomb-dissociation method. This can be done at the LAN D/R3B setup at GSI. Recent examples applying this method to radioactive be ams will be presented. \n\nThis project is supported by the HGF Young Inve stigators Project VH-NG-327.\n\nhttp://indico.cern.ch/contributionDisplay. py?contribId=99&sessionId=10&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=99&sessionId=10 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Production and Manipulation of Radioactive Ion Beams DTSTART;VALUE=DATE-TIME:20100608T070000Z DTEND;VALUE=DATE-TIME:20100608T073000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-98@cern.ch DESCRIPTION:Speakers: Dr. MOORE\, Iain D.

With ever increasing primary beam intensities\, the ability to handle unwanted secondary contam inants is of particular interest.

With the c onstruction of SPIRAL2 over the next few years\, GANIL is in a good positi on to retain its world-leading capability even though it faces strong comp etition from new and upgraded ISOL and fragmentation facilities. \nAs sele cted by the ESFRI committee\, the next generation of ISOL facility in Euro pe is represented by the SPIRAL2 project to be built at GANIL (Caen\, Fran ce). SPIRAL 2 is based on a high power\, CW\, superconducting LINAC\, de livering 5 mA of deuteron beams at 40MeV (200KW) directed on a C converter + Uranium target and producing therefore more 1013 fissions/s. The expecte d radioactive beams intensities in the mass range from A=60 to A=140\, wil l surpass by two order of magnitude any existing facilities in the world. These unstable atoms will be available at energies between few KeV/n to 1 5 MeV/n. The same driver will accelerate high intensity (100*A to 1 mA)\, heavier ions (Ar up to Xe) at maximum energy of 14 MeV/n.\n In applied are as SPIRAL2 is considered as a powerful variable energy neutron source. The Neutrons For Science collaboration (NFS) is proposing a physics program o n fission induced by fast neutrons as well as fusion studies on materials. \n Under the 7FP program of European Union called*Preparatory phase*\, the SPIRAL2 project has been granted a budget of about 4M€ to build up an i nternational consortium around this new venture. The status of the constru ction of SPIRAL2 accelerator and associated physics instruments in collabo ration with EU and International partners will be presented\n In addition\ , in order to ensure that the existing GANIL-SPIRAL1 facility makes best u se of available resources\, a study of the prospects for the laboratory h as been undertaken \, which will address its likely needs for the scientif ic programme up to 2015.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=91&sessionId=14&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=91&sessionId=14 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:The FAIR project DTSTART;VALUE=DATE-TIME:20100610T070000Z DTEND;VALUE=DATE-TIME:20100610T073000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-90@cern.ch DESCRIPTION:Speakers: Mr. AUGUSTIN\, Ingo (GSI)\nThis presentation outline s the current status of the Facility for Antiproton and Ion Research (FAIR ).

Beam intensities exceed those available at e xisting rare-Isotope-beam facilities by several orders of magnitude and be am energies are variable up to more than 1GeV/u. A superconducting in-flig ht separator (Super-FRS) serves external stations and coupled storage cool er rings and in a later stage also an electron-ion collider. The novel ins truments and experimental opportunities have attracted a large community o f nuclear physicists addressing a broad research spectrum covering nuclear structure physics\, nuclear astrophysics and studies of fundamental inter actions and symmetries. Altogether 9 experimental programs are currently p lanned at the three branches of the Super-FRS. These programs are organize d in the NuSTAR collaboration (Nuclear Structure\, Astrophysics\, and Reac tions) with more than 700 participating scientists.

The observed fine structure agrees well with the fl uctuations of the lowest particle threshold as a function of neutron and p roton number. The structure is not consistent with the fluctuations of the binding energies. We take this experimental observation as an indication that primary fragments produced in multifragmentation are mostly found in excited states from which a sequential decay originates. The production of the finally observed cold intermediate-mass fragments directly in their g round state seems to be weak. Our study confirms the important role of the deexcitation process in almost all nuclear reactions. We focus our attent ion particularly on multifragmentation reactions\, where sequential decay strongly influences the yields of light fragments\, which are often used t o extract information on the nature of hot nuclear matter.\n\nhttp://indic o.cern.ch/contributionDisplay.py?contribId=94&sessionId=21&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=94&sessionId=21 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Present and future studies of Superheavy Nuclei DTSTART;VALUE=DATE-TIME:20100610T130000Z DTEND;VALUE=DATE-TIME:20100610T133000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-97@cern.ch DESCRIPTION:Speakers: Dr. GREENLEES\, Paul (University of Jyväskylä)\nTh e production and spectroscopic study of the heaviest elements has always b een a central theme of nuclear physics.

The main focus of current experiments is the search for the next closed proton- and neutron- shells beyond the doubly magic 208Pb.\nThis search can be made d irectly\, by producing nuclei in the region of interest (Z>112 and N>176)\ , or indirectly through the study of lighter deformed nuclei where the orb itals of interest at sphericity are active at the Fermi surface.\n\nThe ad vent of next-generation radioactive beam facilities will begin to provide reasonably intense beams of exotic nuclei. Whilst the intensities are not expected to be at the level used in current stable beam facilities\, the b eams still offer a opportunity to extend studies of superheavy nuclei. Neu tron-rich beams will provide a method to populate isotopes not accessible by any other means. The use of more symmetric reactions will allow nuclei in the region of 254No to be populated at higher spin and excitation energ y than currently possible. New opportunities to study reaction dynamics wi th exotic neutron-rich beams will also provide interesting data. The use o f deep inelastic collisions with neutron-rich beams may also be of interes t.\n\nExamples of recent highlights in heavy element studies with stable b eams\, along with the opportunities provided by future facilities to exten d these studies will be presented.\n\n\n[1] Yu.Ts.

The production cros s sections of the selected nuclides are crucial for a successful experimen t\, but also the production rates of all other nuclei is of importance as they define the level of separation that must be reached. With beam intens ities exceeding $10^{10}$ primary beam ions a high reduction factor must b e achieved.\nThe so called $B\\rho-\\Delta E-B\\rho$ method has become the standard method for separation in fragment separators. World wide many de dicated devices have been built or existing beamlines have been modified t o work in this technique. For new separators as BigRIPS or the planned Sup er-FRS a many stage separation scheme with more than only one degrader wil l be employed. This scheme can even be extended by an additional stage for bunching the energy-distribution for implantation into a gas catcher. \nA formalism to calculate analytically the separation characteristics of the se devices will be presented as well as numerical techniques of simulation . The description involves the combination of the ion-optical properties a s well as the energy-loss of heavy ions in matter. The achievable resoluti on as well as limitations from ion-optical imperfections and the energy-lo ss and angular straggling in the degraders will be discussed. \nThe exact characteristics of separation depend on the velocity at which the separato r is operated and strong differences even in the energy domain of 100-1000 MeV/u are the result. Ions of different charge states can confuse the par ticle identification and require special care for separation. \nAnother in teresting possibility comes with the coupling to storage rings where after beam cooling much higher resolving powers can be achieved.\n\nhttp://indi co.cern.ch/contributionDisplay.py?contribId=96&sessionId=9&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=96&sessionId=9& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:MUSETT and the spectroscopy of heavy elements at GANIL DTSTART;VALUE=DATE-TIME:20100607T153000Z DTEND;VALUE=DATE-TIME:20100607T154000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-17@cern.ch DESCRIPTION:Speakers: Dr. THEISEN\, christophe (CEA Saclay)\nCh. THEISEN f or the MUSETT collaboration\n\nIn the last few years\, an impressive amoun t of new information has been obtained in the region of the heaviest eleme nts. Detailed information has been obtained on the collective properties a nd single-particle structure using both prompt and decay spectroscopy tech niques. \n\nHowever\, very little data are available for nuclei located on the less neutron-deficient side of this region of the nuclear chart. Inde ed\, these isotopes can only be populated in very-asymmetric hot fusion-ev aporations reactions using light-ion beams and actinide targets with the c onsequence that the recoiling nuclei have a very large angular distributio n and a very low kinetic energy. The transmission of separators or spectro meters is usually poor for such reactions. With its very large acceptance providing a high transmission\, VAMOS is well adapted to these studies\; r ecoils are detected in the new MUSETT silicon detector array (“Mur de Si licium pour l’Etude des Transfermiens par Tagging”)\, which has been d eveloped for the detection of the very heavy and very slow fusion-evaporat ion residues and for alpha-decay tagging. MUSETT is made of 4 segmented do uble-sided silicon detectors (128 strips on each side) assembled in a wall having a total size of 40x10 cm2 covering the VAMOS focal plane. Given th e very large number of strips a new highly integrated ASIC based electroni cs and data acquisition system have been developed. Recoil-decay tagging w ill be used to unambiguously identify evaporation residues in the dominant backgrounds of unwanted reaction channels\, while EXOGAM will provide a l arge efficiency for the detection of prompt gamma-ray cascades.\n\nIn this contribution\, we will first give an overview of our experimental program on transfermium and transactinides elements studies. We will then describ e the new MUSETT silicon wall and show the results of the first commission ing experiment. A new gas-filled operation mode has been recently implemen ted at VAMOS\, which extends the capability of the spectrometer in symmetr ic and inverse kinematics fusion-evaporation reactions. Examples of nuclea r structure and reaction dynamics studies using this new mode and MUSETT w ill be given. In a near future the Super Separator Spectrometer S3 and the ultra-high intensities of the LINAG linear accelerator will provide fanta stic opportunities for decay-spectroscopy studies. We will show how the S3 focal plane detection will benefit from the MUSETT developments and give examples of first-day experiments foreseen with S3 in 2013.\n\nhttp://indi co.cern.ch/contributionDisplay.py?contribId=17&sessionId=8&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=17&sessionId=8& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:The new intermediate energy in flight facility ACCULINNA-2 DTSTART;VALUE=DATE-TIME:20100610T093000Z DTEND;VALUE=DATE-TIME:20100610T095000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-16@cern.ch DESCRIPTION:Speakers: KAMINSKI\, G.

Since the nucleus u nder study is the one which is produced in the process of in-flight fragme ntation\, one has to deal with inverse kinematics in which the hadronic pr obe\, generally a light nucleus\, is the target being bombarded by the hea vy nucleus. The inverse kinematics will impose particular conditions on th e design of detection systems. In the EXL project\, heavy ion beams are fi rst cooled in the New Experimental Storage Ring (NESR) and then used to in duce reactions on windowless thin hydrogen\, deuterium and Helium gas targ ets in the ring. High luminosities can be achieved because the beam circul ates a couple of million times in the ring.

München)\nAlong with the availability of high power\, sho rt pulse lasers arises the perspective of generating ultra-dense\, laser-a ccelerated ion beams\, which is one of the most active fields of research in virtually all major high-power laser laboratories world-wide. We plan t o apply the new Radiation Pressure Acceleration (RPA) mechanism for ion ac celeration\, which was recently observed [1\,2\,3]. We are exploring the p ossibility to establish a new nuclear reaction mechanism\, fission-fusion\ , where in a first step bunches of solid state density of e.g. ^232Th with about 10 MeV/u will be produced (thus exceeding the density of ion bunche s from classical accelerators by about 15 orders of magnitude)\, which the n pass through a second Th foil where they desintegrate into light and hea vy fission fragments. A strongly reduced atomic stopping power is expected in the interaction of the very dense ion bunches via collective effects\, which is important to obtain intense fission fragment beams. \n\nThe high density of the projectile and target ions furthermore leads to a reasonab le subsequent fusion yield between neutron-rich light fission fragments. T his may grant access to the production of extremely neutron-rich nuclei in the region of the astrophysical r-process near the waiting point N=126. M oreover\, highly brilliant gamma-beams with MeV energies can be produced v ia Compton-backscattering of laser photons (ca. 1 eV) off brilliant electr on bunches from conventional accelerators (storage ring or energy recovery linac). High-resolution spectroscopy (Delta E_gamma/E_gamma ~ 10^-4) usin g nuclear the resonance fluorescence technique can be applied to shed new light on short-lived neutron-deficient nuclei relevant for the astrophysic al p- or rp nucleosynthesis processes. Ultra-dense laser ion acceleration as well as a brilliant gamma source based on the above concept is presentl y under study for the nuclear physics pillar of the European ELI (Extreme Light Infrastructure) large scale research facility to be built within the next 5 years in Bucharest [4]. \n\n[1] A.

It was suggested th at the PDR is due to an oscillation of a small \nportion of neutron-rich n uclear matter relative to the rest of the nucleus. \nHere\, we present sys tematic investigations based on self-consistent HFB and QPM theory on dipo le and other multipole excitations in several isotonic and isotopic chains of nuclei\, particularly exploring their connection to the thickness of t he neutron or proton skin\, respectively [1-3].\nFrom the analysis of the structure of low-energy electric dipole and quadrupole states and the corr esponding neutron and proton transition densities a Pygmy Dipole [1\,3] an d a Pygmy Quadrupole Resonances (PQR) [2] are identified as a distinct and unique excitation\, different from giant resonances and low-energy collec tive quadrupole states\, respectively.

The observed changes help to shed light on specific terms of the effective nucleon-nucleon interaction and t o improve our knowledge of the nuclear structure evolution towards the dri p lines. In particular\, it has been shown that the monopole part of the t ensor force of the proton-neutron interaction gives the main contribution to the shell evolution.

The Resonance Ionizat ion Laser Ion Source (RILIS) is the only ion source capable of achieving h igh ionization efficiency combined with chemical selectivity for many diff erent elements. By using up to three broadly tunable dye lasers with opti onal second or third harmonic generation\, ionization schemes for 27 eleme nts have been successfully applied for ion beam production. Until 2008\, the RILIS relied on copper vapor lasers (CVLs) to pump tunable dye lasers and to ionize highly excited atoms. The maintenance and operation of the CVLs manufactured almost 20 years ago required substantial efforts. A ne w CERN\, KTH (Stockholm) collaboration funded by a grant from the Knut and Alice Wallenberg foundation was established with the goal of improving th e RILIS performance through a series of upgrade steps.  The first of thes e\, the replacement of the CVLs with a commercial Nd:YAG laser\, began in 2008 and by 2009 the new laser was fully integrated into the RILIS setup and the CVLs were no longer required.  An improvement in RILIS performanc e in terms of ionization efficiency\, as well as overall stability and rel iability has been achieved.  The second phase of the RILIS upgrade is un derway and involves the replacement of the dye lasers.  The three new dye lasers are adapted to take advantage of the availability of a 355 nm out put of the Nd:YAG pump laser\, extending the fundamental tuning range into the blue part of the spectrum to bridge the gap in the spectral coverage offered by the dye laser fundamental and second harmonic beams of the 532 nm pumped system.  One laser has a motorized intra-cavity etalon which re duces its linewidth to 1 GHz. This is necessary for precision tuning to hy perfine components of an electron energy level to perform an isomer separa tion with RILIS\, or for high resolution scanning during in-source resonan ce ionization spectroscopy studies. The third RILIS upgrade task is the in stallation of a complementary\, all solid state RILIS system of Nd:YAG pum ped Titanium Sapphire lasers\, alongside the existing setup.  The constru ction of this system\, which is being carried out in collaboration with t he University of Mainz\, began in 2009 and its progressive installation du ring 2010/2011 is planned. \n\nhttp://indico.cern.ch/contributionDisplay. py?contribId=75&sessionId=9&confId=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=75&sessionId=9& confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Observation of gamma-delayed three-alpha breakup in 12C: a complet e kinematics approach to study multi-particle final state reactions DTSTART;VALUE=DATE-TIME:20100608T150000Z DTEND;VALUE=DATE-TIME:20100608T152000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-74@cern.ch DESCRIPTION:Speakers: Dr. TENGBLAD\, Olof (Consejo Sup. de Investigac. Cie ntif (CSIC))\nHans Bethe was the first to establish the concept of nucleon synthesis in stars [1] proposing the CNO cycle and the PP chain\, but was unsuccessful in solving the 12C formation mechanism. Not until the introd uction of the Hoyle state [2] in 1953 one was getting close to a solution. However\, 50 years later the 12C break-up is still not fully solved and t he quest for learning more about the reaction rates in stars by studying t he triple-alpha process is continuing.\n\nIn this work we have studied the break-up of 12C following the reactions 10B(3He\,pααα) and 11B(3He\,d ααα). The study was performed at the 5MV tandem accelerator at the Cent ro de Micro Analysis de Materials (CMAM) [3] at the Universidad Autónoma de Madrid. The break-up give us information on excited states in 12C fro m the famous Hoyle state up to an energy of almost 18 MeV. Using a highly segmented experimental set-up the simultaneous detection of the three alp ha particles in coincidence with a proton or a deuteron\, respectively\, made possible a full kinematic reconstruction of the break-up. On the basi s of the energies of the three alpha particles and their angular correlati ons it has been possible to separate the branching of the break-up through the ground state and the first excited 2+ state in 8Be\, as well as to de termine the spin and parity of states for cases where the assignment have been doubtful. \n\nSome of these levels will also de-excite via electromag netic emission. The comparison between the energy of the proton (or deuter on) that populate a state of 12C and the sum of the energies of the 3alpha emitted from the same state makes possible to determine the presence of e lectromagnetic disintegration (γ) to lower states within 12C followed by the 3α break-up. This technique permits to identify γ-emissions between states where the gamma radiation emitted does not correspond to a peak [4 ]. \n\nIn this contribution we will discuss the experimental set-up follow ed by a detailed description of the analysis method to reach the results o btained.\n\n[1] H.A.

The short-lived isotopes are produced at ISAC by the ISOL (on-line isotope separation) method using a beam of up to 100uA of 500 MeV protons from th e TRIUMF H- cyclotron to bombard thick production targets. The targets ca n be coupled to a wide variety of ion sources including: surface\, laser ( TRILIS) and plasma (FEBIAD) sources\, to produce the worlds most intense R IB beams for certain isotopes such as 11Li. \n Low-energy ( \n\nh ttp://indico.cern.ch/contributionDisplay.py?contribId=70&sessionId=15&conf Id=61310 LOCATION:Conference Hall URL:http://indico.cern.ch/contributionDisplay.py?contribId=70&sessionId=15 &confId=61310 END:VEVENT BEGIN:VEVENT SUMMARY:Active target ACTAR for the low-energy short-lived radioactive SPI RAL2 beams DTSTART;VALUE=DATE-TIME:20100607T160000Z DTEND;VALUE=DATE-TIME:20100607T161000Z DTSTAMP;VALUE=DATE-TIME:20130523T214749Z UID:indico-contribution-61310-79@cern.ch DESCRIPTION:Speakers: Dr. NALPAS\, Laurent (CEA Saclay)\nThe active target s (AT) are promising tools for the study of low-energy short-lived radioac tive beams available in the next decade at SPIRAL2\, HIE-ISOLDE\, NSCL and RIKEN. They are based on a gaseous ionization detector for the measuremen t of the incoming radioactive ions and their particle decay stopping in th e volume. Alternatively\, the nuclei of the gas can interact as a target w ith the beam to study induced direct reaction in inverse kinematics. The a ctive targets provide high efficiency\, low detection threshold and ion tr acking capabilities allowing angular distribution and energy measurements. The validity of the method has been demonstrated with the first generatio n of detection set-ups developed at Bordeaux [1] and Ganil [2-3]. The ACTA R (Active TARget) collaboration aims to build a new active target\, workin g as a time-projection chamber (TPC)\, able to record the 3D-tracks of ion izing particles passing through the gas volume and to work with medium-mas s high-intensity radioactive beams. The ACTAR joint research initiative ha s promoted an R&D program gathering 9 European laboratories led by Ganil t o define the characteristics of ACTAR [4]\, namely a highly segmented cath ode (25 pads/cm2) representing more than 10’000 electronic channels\, ha ving a large dynamic range (both in energy and time)\, self-triggering and high-data rate capabilities. A specific R&D program called GET (General E lectronics for TPC) has been started by IRFU/Saclay\, CENBG/Bordeaux\, GAN IL/Caen and NSCL/MSU to build in a 4-year plan a generic front-end electro nics for AT-TPC. The French ANR and US agencies have already funded the pr oject. It will be a modular scale-free system able to read various AT-TPC within the ACTAR specifications. \n\n[1] J.
