Description

Silicon Photomultipliers (SiPMs) are extremely versatile photo-sensors and can be used in many fields ranging from astrophysics, particle and nuclear physics to medical imaging. Recently, we have built a prototype of a position sensitive photo-detector with 5.6 x 5.6 cm² detection area readout with 64 Hamamatsu MPPCs (S10931-100P) with 3 x 3 mm² active area each. The photo-sensors are arranged in a 8 x 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. Results of first tests with the 64 channel SiPM module will be presented.
