Abstract: (Elsevier)

• An overview of the FRS Ion Catcher experiment at GSI is given. • The FRS Ion Catcher consists of the FRS, a cryogenic stopping cell, an RF quadrupole-based beam transport and diagnostics unit and a multiple-reflection time-of-flight mass spectrometer. • Off-line tests of the stopping cell with 219 Rn ions. • First on-line operation of a stopping cell for exotic nuclei at cryogenic temperatures. • First mass measurements of heavy projectile fragments using a multiple-reflection time-of-flight mass spectrometer.
