Development of a novel single-channel, 24~cm${}^2$, SiPM-based, cryogenic photodetector

Abstract

We report on the realization of a novel SiPM-based, cryogenic photosensor with an active area of 24 cm${}^2$ that operates as a single-channel analog detector. The device is capable of single photon counting with a signal to noise ratio better than 13, a dark rate lower than $10^{-2}$ cps/mm${}^2$ and an overall photon detection efficiency significantly larger than traditional photomultiplier tubes. This development makes SiPM-based photosensors strong candidates for the next generation of dark matter and neutrino detectors, which will require multiple square meters of photosensitive area, low levels of intrinsic radioactivity and a limited number of detector channels.
