In this work we will document the design and the performances of a SiPM-based photodetector with a surface area of 100 cm(2) conceived to operate as a replacement for PMTs. The signals from 94 SiPMs are summed up to produce an aggregated output that exhibits in liquid nitrogen a dark count rate (DCR) lower than 100 cps over the entire surface, a signal to noise ratio better than 13, and a timing resolution better than 5.5 ns. The module feeds about 360 mW at 5 V with a dynamic range in excess of 500 photo-electrons on a 100 Omega differential line. The unit can also operate at room temperature, at the cost of an increase of DCR to 10(8) cps.

Abstract
In this work we will document the design and the performances of a SiPM-based photodetector with a surface area of 100 cm(2) conceived to operate as a replacement for PMTs. The signals from 94 SiPMs are summed up to produce an aggregated output that exhibits in liquid nitrogen a dark count rate (DCR) lower than 100 cps over the entire surface, a signal to noise ratio better than 13, and a timing resolution better than 5.5 ns. The module feeds about 360 mW at 5 V with a dynamic range in excess of 500 photo-electrons on a 100 Omega differential line. The unit can also operate at room temperature, at the cost of an increase of DCR to 10(8) cps.Pubblicazioni consigliate
