Performance of CBM TRD Prototypes from Münster — •Cyrano Bergmann — Institut für Kernphysik WWU, Münster, Deutschland

CBM is a fixed target heavy-ion experiment at the future FAIR accelerator facility. The CBM Transition Radiation Detector (TRD) is one of the key detectors to provide electron identification and charged particle tracking. Based on the ALICE TRD design, two CBM TRD prototype modules of 59×59 cm2 were built in Münster and tested during October 2012 in beam at the CERN Proton Synchroton (PS) with electrons and pions of momenta up to 10 GeV/c. Readout was performed with the time sampling Self-triggered Pulse Amplification and Digitization asIC (SPADIC), an especially designed front-end electronics component for the CBM TRD. The objectives of the beam test included measurements of: electron identification performance for different regular and irregular radiators, position resolution and dependence on particle momentum. First results of these measurements will be presented. The layout of the final TRD will be driven by these beam test results. Depending on the achieved electron identification performance, the TRD could be constructed in 6-10 layers, consisting in total of several 100 individual detector modules covering an area of up to 600 m2.

Work supported by BMBF and the HadronPhysics3 project financed by EU-FP7.
