Position sensitive SiPM detector for Cherenkov applications

A prototype of a position sensitive photo-detector with 5.6 × 5.6 cm2 detection area readout with 64 Hamamatsu MPPCs (S10931-100P) with 3 × 3 mm2 active area each has been built and tested. The photo-sensors are arranged in a 8 × 8 array with a quadratic mirror light guide on top. The module is currently readout by in-house developed preamplifier boards but employing existing ASIC chips optimized for SiPM readout is also planned. Such a device is one of the candidates to be used for photon detection in the PANDA DIRC detectors.
