Status of the Readout Chain for the CBM-TRD Experiment — •Cruz de Jesus Garcia Chavez for the CBM collaboration — Institut für Kernphysik, WWU Münster, Germany

The Transition Radiation Detector (TRD) is part of the Compressed Baryonic Matter (CBM) experiment at FAIR. During 2017, the TRD readout chain featured important upgrades such as the introduction of the new Self-triggered Pulse Amplification and Digitization asIC (SPADIC) version 2.0, which implements the STS-HCTSP protocol for data transmission to the Data Processing Board (DPB), developed on the AMC FMC Carrier Kintex (AFCK) FPGA. This later implements a FLIM data transmission protocol to the FLES Interface Board (FLIB). The slow control and configuration for the DPB as well as for the front-ends is based on the (IPbus) protocol.

Results and evaluation of the readout chain during testbeam measurements performed in 2017 using Multi-Wire Proportional Chambers (MWPCs) at DESY II electron beam and on the Gamma Irradiation Facility (GIF⁺⁺) at CERN will be presented together with an overview of the new SPADIC 2.1 protocol and the commissioning status.
