Test of front-end electronics with large dynamic range coupled to SiPM for space-based calorimeters

Recent advances in the development of silicon photodetectors working in the Geiger mode (SiPM), open new perspectives in space-based or balloon-borne calorimetry. However, present SiPM devices suffer from a number of limitations, including the instrinsic dynamic range of the photodetector and its operational stability, that have to be overcome in view of their utilization in ionization calorimetry. Test results will be presented on the readout performance of a SiPM prototype, optically coupled to scintillating fibers, and connected to low-noise front-end electronics with large dynamic range.
