Poster

The ISOLDE Solenoidal Spectrometer (ISS) is a new experimental station based on the second HIE-ISOLDE beam line. Based on the HELIOS concept developed at Argonne National Laboratory (ANL) [1], the experiment consists of a 4 T former MRI magnet and on-axis silicon detector array for the detection of light ions. Various ancillary devices are to be used for the coincident detection of recoil...

42. Transfer-induced fission in inverse kinematics with solenoidal spectrometers

Samuel Alexander Bennett (University of Manchester (GB))

03/12/2019, 17:42

Poster

Studying transfer-induced fission in inverse kinematics offers advantages over neutron-induced fission measurements in normal kinematics. Two such advantages include the ability to measure fission barrier heights of fissile nuclei due to the addition of a third body to the system, and the possibility to study the fission properties of short-lived actinides where fixed targets are not feasible;...

11. MIRACLS: A novel approach for Collinear Laser Spectroscopy

Varvara Lagaki (Ernst Moritz Arndt Universitaet (DE))

03/12/2019, 17:46

Poster

Due to its high accuracy and resolution, collinear laser spectroscopy (CLS) is a powerful tool to measure nuclear ground state properties such as nuclear spins, electromagnetic moments and mean-square charge radii of short-lived radionuclides. Performing CLS with fast beams (>30 keV) provides an excellent spectral resolution approaching the natural linewidth. However, its fluorescence-light...

12. MINIBALL - versatile HPGe array for experiments with post-accelerated RIBs at ISOLDE

Thorsten Kroell (Technische Universitaet Darmstadt (DE))

03/12/2019, 17:48

Poster

The MINIBALL array consists of 24 6-fold segmented, individually encapsulated, HPGe detectors [1]. MINIBALL was one of the first arrays of such size with a fully-digital triggerless DAQ system. It has been operated very successfully at ISOLDE since the beginning of REX-ISOLDE and is still the main instrumentation for experiments with post-accelerated radioactive ion beams from HIE-ISOLDE. For...

14. The PUMA experiment at CERN/ISOLDE

Dr Frank Wienholtz (CERN)

Poster

Frank Wienholtz for the PUMA Collaboration

The PUMA experiment aims to use antiprotons as a tool for exploring the properties of exotic nuclei by probing the distribution of the protons and the neutrons on the surface of the nucleus. To be able to do this, a mobile Penning-trap system must be designed and built which will allow to transport antiprotons from CERNs antiproton decelerator (AD)...

15. The SpecMAT active target for transfer reaction studies at HIE-ISOLDE

Oleksii Poleshchuk (KU Leuven, Institute for Nuclear and radiation Physics)

03/12/2019, 17:52

Poster

The SpecMAT active target will be used for the study of isotopes in the exotic regions of the chart of nuclide, to investigate the fundamental questions related to the shell structure of nuclei far from stability via nucleon-transfer reactions in inverse kinematics. The active target will be placed in a high and homogeneous magnetic field of up to 2.4 T at HIE-ISOLDE (CERN) for reconstruction...

16. Search for physics beyond the Standard Model with radioactive beams

Dinko Atanasov (CERN)

03/12/2019, 17:54

Poster

The search for physics beyond the standard electroweak model (SM), despite its remarkable success at the most elementary level, still continues on three frontiers - high-energy, precision and cosmic. The reason is the many yet unanswered questions such as the origin of parity violation [1].
Considering the precision frontier, experiments with radioactive nuclei offer large variety of nuclear...

17. Target developments at KU Leuven

Prof. Thomas Elias Cocolios (KU Leuven - IKS)

03/12/2019, 17:56

Poster

The Isotope Separation On-Line (ISOL) method is a powerful technique to produce radioactive ion beams (RIB), and thus, is an essential tool when studying the properties of atomic nuclei far away from the valley of stability. The ISOL method gives, in principle, access to a large number of the known (radio-)isotopes of the chart of nuclides, with relatively large intensity and purity. Key...

18. Towards a beta spectrum shape measurement at WISArD

Simon Vanlangendonck (KU Leuven (BE))

03/12/2019, 17:58

Poster

There are indications that the measured number of antineutrinos emerging from reactor fission fragments inside a reactor is lower than theoretically predicted. Moreover, there is an additional anomaly in the energy spectrum of the antineutrinos. These observations are the reactor neutrino anomaly. One of the uncertainties in the theoretical description is the QCD influence on the β-decay of...

20. Development of a fast and highly selective ISOLDE MR-ToF device

Markus Vilen (CERN)

03/12/2019, 18:00

Poster

As experimental methods for fundamental science and applications at radioactive ion beam (RIB) facilities are expanding our scientific horizon, their demands on the quality of the RIB perpetually increase. In this regard, (isobaric) contaminants in the RIB have long been identified as a major obstacle. Indeed, when probing nuclides towards the limits of nuclear existence, an overwhelming...

26. Double target front-ends: an inexpensive alternative to additional front-ends

Miguel Luis Lozano Benito (CERN)

03/12/2019, 18:04

Poster

One of the core components of the EPIC project is the installation of two additional target stations following the existing GPS and HRS ones. Protons from the PS Booster (PSB) could be shared among two or more of these four target stations producing several Radioactive Ion Beams (RIBs) that could be delivered to different experimental stations in parallel. However, the effective proton current...

44. An alternative layout proposal for ISOLDE Target Area

Mr Stefano Marzari (CERN)

03/12/2019, 18:06

Poster

This is an alternative conceptual design of a target area layout of ISOLDE. This concept will require shielding consolidation and a different approach to operational scenarios. In a first approach, this design focuses on the handling and maintenance aspects for future upgrades in the target area. The increase of radiation levels due to higher proton beam current and energy after LS3 will...

19. The new set up at SSP ISOLDE CERN

Sergey K Dedushenko (Moscow Institute of Physics and Technology State University (RU)

Poster

Ion implantation is a useful way for a modification of a substance. It allows us to introduce the desired nuclide into a substance (substrate) quickly, without impurities, and without formation of the local accumulations (clusters) of the respective element. Moreover, the implantation does not change the structure, temperature etc. of the substrate, though local changes are possible. These...
