  2. 0. The TSR@ISOLDE Project
    Prof. Klaus Blaum (Max-Planck-Institut für Kernphysik)
    29/10/2012, 09:10
    Submitted
    The TSR will be the first low-energy storage ring at an ISOL-type radioactive beam facility. Specifically, we intend to setup the heavy-ion, low-energy ring TSR at the ISOLDE facility in CERN, Geneva. Such a facility will provide a capability for experiments with stored secondary beams that is unique in the world. The envisaged physics programme is rich and varied, spanning from...

  4. 12. Isomer physics in the TSR at ISOLDE
    Prof. Philip Walker (University of Surrey)
    29/10/2012, 10:00
    Most of the beams injected into the TSR at ISOLDE will be in their nuclear ground states. However, isomers offer additional opportunities, providing their half-lives are sufficiently long (about a second or longer). These opportunities are of two kinds. (i) The opening up of the spin and excitation-energy degrees of freedom gives access to a wider range of nuclear structure, such as...

  5. 14. Nuclear Astrophysics with the TSR@ISOLDE
    Philip J WOODS
    29/10/2012, 11:00
    The talk will explore important new opportunities that will become available for nuclear astrophysics on the TSR@ISOLDE. Measurements will be performed for reactions influencing nucleosynthesis and energy generation in explosive environments such as novae, supernovae and X-ray bursters. In particular, there will be an emphasis on the use of high resolution transfer reactions for estimates of...

  6. 13. In-flight beta-decay of light exotic nuclei
    Riccardo Raabe (Katholieke Universiteit Leuven (BE))
    29/10/2012, 11:30
    The peculiar properties of light exotic nuclei have been investigated using nuclear reaction at high and intermediate energies. The extraction of reliable information on their structure, however, depends on reaction models; beta-decay studies can be seen as complementary in this context. The beta-decay process has the advantage of being well understood. The decay probability directly relates...

  7. 9. Isospin dependence in heavy-element synthesis in fusion-evaporation reactions with neutron-rich radioactive ion-beams
    Dr Alexander Yakushev (GSI Helmholtzzentrum für Schwerionenforschung GmbH)
    29/10/2012, 12:00
    Climbing up the "Island of Stability" and approaching the long-predicted next spherical neutron shell closure at N=184 is a persistent dream hampered, among others, by the lack of (i) sufficiently neutron-rich target and projectile combinations and (ii) insufficient knowledge about the projectile isospin (T=(N-Z)/2) dependence of the fusion neutron-evaporation residue cross section. With the...

  8. 5. Dielectronic Recombination of Low-Energy Isomers: Towards Storage Ring Studies of the `Nuclear Clock' Isotope Thorium-229
    Dr Carsten Brandau (ExtreMe Matter Institute EMMI and Research Division, GSI Helmholtzzentrum für Schwerionenforschung, Planckstraße 1, 64291 Darmstadt, Germany)
    29/10/2012, 12:30
    Long-lived atomic or nuclear states play an important role in astrophysics, for precision spectroscopy, for the study of fundamental symmetries, for energy storage or —based on their small natural widths—for applications as clocks. Within the scope of low-energy isomers 229(m)Th is truly outstanding in many aspects. It is presumed that 229 Th posses an isomeric state with excitation energy as...

  9. 6. Atomic Physics Experiments at TSR@ISOLDE
    Prof. Stefan Schippers (Justus-Liebig-University Giessen, Institute for Atomic and Molecular Physics, Leihgesterner Weg 217, 35392 Giessen, germany)
    29/10/2012, 14:00
    TSR@ISOLDE will provide new possibilities for atomic physics experiments with highly charged atomic ions addressing atomic structure (atomic lifetimes, spectroscopy with lasers and ultra-cold electron beams) and atomic collision processes (electron-ion recombination, electron-ion impact ionization). This research is motivated by fundamental physics questions and by applications in...

  10. 11. Laser Spectroscopy studies at the TSR
    Kieran Flanagan (University of Manchester (GB))
    29/10/2012, 14:30
    The TSR presents an excellent opportunity to study difficult cases previously inaccessible for laser spectroscopy at ISOLDE. Deep UV transitions (within the vacuum ultraviolet ) which are currently difficult to study, will be Doppler shifted by up to 30 nm at 10 MeV/A. By partially stripping the ion in the REX-EBIS it is possible to preferentially populate metastable states with transitions...

  11. 18. The low energy Storage Ring - CRYRING@ESR - Project
    Dr Frank HERFURTH (GSI Darmstadt)
    29/10/2012, 15:00
    The Swedish in-kind contribution to the FAIR facility in Darmstadt, the heavy-ion storage ring CRYRING will be transported to Darmstadt this year. Instead of warehousing until installation at the Facility for Antiproton and Ion Research, FAIR, the immediate installation behind the existing Experimental Storage Ring, ESR, has been proposed and worked out in detail by a Swedish-German working...

  12. 3. Overview of the Heidelberg Heavy ion storage ring TSR
    Manfred Grieser (Max Planck Insititut für Kernphysik)
    29/10/2012, 16:00
    In the late eighties and beginning of the nineties a number of laboratories started construction of synchrotrons or small storage rings for light and heavy ions for research in various fields of atomic, molecular and nuclear physics. The small rings became possible due to the successful demonstration of phase space cooling as well the progress in vacuum technology allowing vacua in the 10-12...

  13. 4. The linking of TSR to ISOLDE
    Fredrik John Carl Wenander (CERN)
    29/10/2012, 16:30
    With the integration of the Heidelberg Test Storage Ring at ISOLDE it would become the first storage ring at an isotope separator on-line (ISOL) facility. A substantial fraction of the vast number of radioactive beams produced at the ISOLDE facility could be injected into the ring for storage, beam deceleration or acceleration. The different operational possibilities and constraints that arise...

  14. 16. Installation at ISOLDE (and costs)
    Erwin Siesling (CERN)
    29/10/2012, 17:00
    Several studies have started in the frame of an installation and integration of the TSR at Isolde. With spacing being a problem at Isolde all different options for a possible position of the new building to house the storage ring have been taken in consideration in an early phase of th eproject as well as allocation of parts of the infrastructure such as cooling station and electrical...

  17. 8. Survival of beta decaying nuclei relevant for a neutrino factory
    Dr Alejandro ALGORA (IFIC (CSIC-Uni. Valencia))
    30/10/2012, 09:30
    For many neutrino physics applications it is desirable to have an intense tunable neutrino source. In [1] the β-beam concept for constructing a neutrino-antineutrino facility was proposed. The idea is to obtain a collimated neutrino beam by accelerating radioactive ions to high energy, which subsequently β decay in the long arms of a heavy-ion storage ring. In Ref. [1], two radioactive nuclei...

  18. 7. Detector developments for storage ring experiments
    Dr Takayuki Yamaguchi (Saitama Univ.)
    30/10/2012, 10:00
    As a next generation spectroscopic tool, heavy-ion cooler storage rings will be a unique application for stored highly-charged ion (HCI) beam experiments. The storage rings provide us with an excellent particle identification capability, even for isomeric states, an efficient use of rare isotopes, and an internal target system. In case that the magnetic rigidity of the decay daughters of...

  19. 15. UHV CAPABLE DETECTOR SYSTEMS FOR NUCLEAR REACTION STUDIES WITH STORED EXOTIC BEAMS
    Prof. Peter Egelhof (GSI Helmholtzzentrum für Schwerionenforschung GmbH)
    30/10/2012, 11:00
    Within the R&D for the EXL* project at FAIR the EXL collaboration has developed in the recent years new techniques for the application of large solid angle DSSD`s under UHV conditions of storage rings. Such technologies could be favourably applied at the TSR@ISOLDE project for high energy- and angular resolution detection of target like recoil ions and beam like reaction products from light...

  20. 1. A HELIOS spectrometer for HIE-ISOLDE
    Dr David Jenkins (University of York)
    30/10/2012, 11:30
    The HELIOS concept is a new approach to the study of transfer reactions in inverse kinematics using a large solenoidal magnet. Light ions are transported in helical trajectories in this field and detected in silicon detectors along the axis. Particles can be discriminated on the basis of their cyclotron period and the kinematics reconstructed. This leads, in principle, to improved resolving...

  21. 2. Status and Future Perspectives of the HIE-ISOLDE Project
    Yacine Kadi (CERN)
    30/10/2012, 12:00
    A major upgrade called High Intensity and Energy ISOLDE (HIE-ISOLDE) was approved by the CERN Research Board in 2009 and is currently under construction. A new superconducting LINAC will increase the energy of the post-accelerated beams to 5.5A MeV (2014) and subsequently 10A MeV (2017) while an improved target area will be designed to make use of the higher intensities delivered by LINAC4 and...
