First measurements on the new FPGA-based DIRICH MAPMT readout* — •Vivek Patel, Karl-Heinz Kampert, and Christian Pauly — Wuppertal university

The DIRICH module is the core part of a new readout chain for multianode PMTs and MCPs, being developed in a joined effort by the CBM-, HADES- and PANDA collaborations for their respective RICH detectors. The design focuses on excellent timing precision, limited by the Transit Time Spread(TTS) of the sensors (MAPMTs: ∼ 300 ps, MCPs: <100 ps). Discriminination, time- and time-over-threshold measurement, as well as digital data handling, are all implemented on a single Lattice ECP5 FPGA, providing a cost-effective and highly compact solution. First prototypes of the DIRICH module are available for testing in the lab, and also using a dedicated test chamber with single photon light source, which will later allow for a complete system test of the new HADES photon detector prior its installation in the HADES RICH. In the talk we will present first tests and performance measurements on the DiRICH.
