Measurements with CBM-TRD Prototypes at the CERN SPS in 2015 — •Patrick Schneider and Dennis Spicker for the CBM collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt am Main

CBM as the heavy-ion experiment at FAIR is designed to investigate the properties of strongly interacting matter at highest net-baryon densities. The main purpose of the Transition Radiation Detector (TRD) will be to discriminate electrons and pions over a large region of particle momenta.

We present two analyses of data acquired in a test-setup with two TRD prototypes in a Pb beam at the SPS at CERN in November and December 2015. These prototypes already have the full size (59x59 cm2) of the final TRD chambers and used SPADIC v1.0 read out electronics.

The first part investigates the capability of the TRD to operate at high hit-rates by analyzing the current measurements at the anode wires, while the second part displays the spatial resolution of the protoypes by analysing time-correlated events measured in the two chambers.

Generally, a good performance of the TRD in the high-rate environment is observed.

Supported by the German BMBF-grant 05P15RFFC1
