Recent Detector Development and Tests — •Elena Rocco for the Super-FRS Experiment collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany

The FRagment Separator [H. Geissel et al., Nucl. Instr. Meth. B70 (1992) 286-297] (FRS) at the GSI is an in-flight separator and a high-resolution magnetic forward spectrometer at the Synchrotron SIS18, operating with relativistic heavy ion beams from proton to uranium, with an energy typically spanning from 500 up to 1500 MeV/u already in successful operation since more than 30 years. The identification in charge (Z) and mass (A) is executed using the Bρ * ToF * DeltaE method. This requires measurements of particle Time of Flight (ToF), magnetic rigidity (Bρ) and energy loss (DeltaE) on an event-by-event basis. Besides the regular maintenance, detector upgrades are performed and planned for the near and far future. This contribution provides a short overview of beam and particle detectors at the FRS, with special emphasis on the time project chamber (TPC), which gives tracking information operating in Ar/CH4 (90/10) at atmospheric pressure and on the planned installation of a second beam profile monitor (current grid) on the second FRS focal plane.
