DiRich - Readout Electronics for DIRC and RICH detectors at FAIR — •Jan Michel1, Vivek Patel2, Christian Pauly2, Peter Skott3, and Michael Traxler3 for the HADES collaboration — 1Goethe-Universität Frankfurt — 2Bergische Universität Wuppertal — 3GSI Helmholtzzentrum Darmstadt

Several experiments at FAIR will make use of Cherenkov detectors, namely the DIRC of the PANDA experiment and the RICH of HADES and CBM. All will be equipped with 64 channel PMTs. The DiRich module is a compact set of read-out electronics that includes all features required for these detectors: The front-end board houses discrete, low-power amplifiers and FPGA-based TDC. Auxiliary boards include a power supply and a data concentrator that provides the connection to the data acquisition system of the detectors using an optical link for data transport. All boards are connected via a 10 by 15 cm sized backplane that doubles as mechanical support for the PMTs and light-tight shielding. We present the electronics along with selected performance test results.

This work has been supported by BMBF grants 05P15PXFCA and 05P15RGFCA and contributions from the TRB3 collaboration.
