SMI-2023: 14th International Conference on Stopping and Manipulation of Ions and Related Topics

Stopping devices provide access to a wide range of exotic radioactive ion beams with precise and low-energies at projectile fragmentation facilities. The stopping process includes slowing down the fast exotic beams in solid degraders combined with momentum compression and removal of the remaining kinetic energy by collision with helium buffer gas. The beam stopping facility at the Facility for...

Jiajun Yu, for the FRS Ion Catcher collaboration

In the FRS Ion Catcher (FRS-IC) [1-3] at GSI, short-lived nuclei produced at relativistic energies of up to 1 GeV/u at the fragment separator (FRS), are slowed down and thermalized in a cryogenic stopping cell (CSC) and identified/separated with a high-accuracy multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS). High-accuracy...

Experiments with thermalized and low-energy exotic nuclides extracted from a gas-filled stopping cell rely on an efficient production, stopping and preparation of the mentioned rare nuclides. However, an often forgotten and only partially considered aspect is the interplay between the separator and the stopping in the stopping cell. Over the years, several novel techniques have been developed...

The Low-Energy Branch (LEB) [1] for the MARA separator [2] is a facility under construction at the Accelerator Laboratory of the University of Jyväskylä. The facility will be used to study the ground-state properties and decay modes of exotic nuclei far from stability combining multiple techniques to investigate nuclear properties of isotopes far from stability.
MARA-LEB will stop and...
