Description:
The FRS Ion Catcher is a set up which slows
down exotic nuclei produced with high energies to perform high precision
measurements almost at rest. The properties of the exotic isotopes help to
study the structure of the nuclei or the origin of the elements in the
universe. The setup is located at the fragment separator (FRS) of the GSI
Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany. The setup has
been designed in collaboration with international partners, e.g.
KVI-CART Groningen, Justus-Liebig-University Giessen, Germany. The FRS Ion Catcher consist in a cryogenic stopping cell, an RFQ based
beamline with improved capabilities and a Multiple-Reflection
time-of-flight Mass Spectrometer (MR-TOF-MS). More details can be found in [1,
