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.
