Test beam results of prototypes for the CBM-TRD at DESY and GIF++ — •Florian Roether for the CBM collaboration — Institut für Kernphysik, Frankfurt, Deutschland

The Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) will explore the QCD phase-diagram in the region of high net-baryon densities. The Transition Radiation Detector (TRD) with its multi-layer-design will provide electron identification and contribute to particle tracking as well as the identification of light nuclei.

The TRD will be constructed from modules of two sizes. Each TRD module consists of a radiator, a thin Multiwire Proportional Chamber (MWPC) and the coresponding Front-End Electronics (FEE).

The evaluation of the performance of these detectors at suitable facilities is a crucial part of the research and development process. The latest large prototypes which were build in a joint effort in Frankfurt and Münster, have been tested in 2017 at DESY and GIF++ (CERN). In this talk we will present results from these testbeam campaigns.
