Status and development of FEBs for the CBM-TRD — •Florian Roether for the CBM collaboration — Institut für Kernphysik, Frankfurt am Main

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 detector signals will be digitized by the Self-triggered Pulse Amplification and Digitization ASIC (SPADIC), collected by the GBTx based Readout Board (ROB) and pre-processed by the Data Processing Board (DPB).

Therefore, the SPADIC is the key component in the TRD Front End Electronic (FEE). This talk will focus on the current status and development of the corresponding Front End Boards (FEBs) for the TRD and on test results from a recent beam test at DESY.

This work is supported by BMBF-grant 05P15RFFC1 and 05P19RFFC1.
