Electron Detection Efficiency of the CBM-TRD Prototypes in Testbeams at DESY — •Adrian Meyer-Ahrens for the CBM collaboration — Institut für Kernphysik, Münster, Germany

The Transition Radiation Detector (TRD) is a part of the Compressed Baryonic Matter (CBM) experiment at FAIR. As electron identification is one of the TRD's main tasks, its electron detection efficiency is an important system property to be determined. For this and other testing purposes testbeam measurements with an electron beam at DESY were taken with current CBM-TRD prototypes in september of 2017. In this talk analysis results leading to the determination of the electron detection efficiency of the used prototypes will be presented. Since the detector prototypes and readout electronics were not yet tested in a large scale setup like the one used at DESY a focus of the analysis was also a general QA of the system.
