Towards multi-hit readout of TPCs for exotic beam tracking — •Timothy Allred1, Joachim Enders1, Jan-Paul Hucka1, Chiara Nociforo2, Stephane Pietri2, Andrej Prochazka2, and Steffen Schlemme1 — 1Institut für Kernphysik, TU Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung
The Super-FRS [1] beam diagnostics system supports the set up and adjustment of the separator and provides tracking and event-by-event particle identification. A TPC-type detector with GEM amplification and with multi-hit single-strip readout is proposed to be used as a tracking detector. The main challenges for such a detector are position resolution below 1 mm, high dynamic range (1000) and high-efficiency tracking up to 10 MHz ion rate.
One of the planned improvements towards a high-rate capability of single-ion tracking is the multi-hit readout of the TPC detectors [2]. Present TPC detectors with delay-line readout were tested with multihit electronics at the GSI fragment separator FRS [3] with Au beam at 1 GeV/nucl. up to 150 kHz. Results will be presented in comparison to single-hit readout.
