Rate-dependent performance of ion chambers for particle-ID at the GSI fragment separator — •Jan-Paul Hucka1, Timothy Allred1, Joachim Enders1, Roman Gernhäuser2, Steffen Maurus2, Chiara Nociforo3, Stephane Pietri3, and Andrej Prochazka3 — 1Institut für Kernphysik, TU Darmstadt — 2Physik Department, TU München — 3GSI Helmholtzzentrum für Schwerionenforschung
At the GSI Fragment Separator (FRS [1]), multi-sampling ion chambers (MUSIC [2]) emplyoing a Frisch grid are used for charge identification of secondary ion beams. At the FAIR Super-FRS, higher rates are expected, and an event-by-event determination of the charge of secondary ions will be needed at rates of several 100000 events per second. The comparison of results from test measurements for the MUSIC performance with that of a recently constructed [3] tilted-electrode gas ion chamber (TEGIC), which was designed similar to the one discussed in Ref. [4], will be presented.
