SiPM and front-end electronics development for Cherenkov light detection

The Italian Institute of Nuclear Physics (INFN) is involved in the development of a demonstrator for a SiPM-based camera for the Cherenkov Telescope Array (CTA) experiment, with a pixel size of 6x6mm2. The camera houses about two thousands electronics channels and is both light and compact. In this framework, a R&D program for the development of SiPMs suitable for Cherenkov light detection (so called NUV SiPMs) is ongoing. Different photosensors have been produced at Fondazione Bruno Kessler (FBK), with different micro–cell dimensions and fill factors, in different geometrical arrangements. At the same time, INFN is developing front–end electronics based on the waveform sampling technique optimized for the new NUV SiPM. Measurements on 1x1mm2, 3x3mm2, and 6x6mm2 NUV SiPMs coupled to the front–end electronics are presented.
