In-beam performance studies of the first full-size CBM-TRD prototypes developed in Frankfurt. — •Pascal Dillenseger — Institut für Kernphysik, Goethe Universität, Frankfurt

The Compressed Baryonic Matter (CBM) experiment at FAIR will explore the QCD phase-diagram by studying fixed-target heavy-ion collisions from 10 to 45 AGeV. The CBM Transition-Radiation Detector (TRD) has to deliver a good tracking and particle identification performance in the high particle-density environment of the experiment. We plan to match the experimental requirements in terms of position resolution and electron identification, employing a thin MultiWire Proportional Chamber (MWPC). This type of readout-concept combined with different radiators was tested using full-size prototypes at the CERN-PS in October 2012. The results of the detector and radiator studies will be presented.
