Development of a very low-noise cryogenic pre-amplifier for large-area SiPM devices

摘要

Silicon Photomultipliers (SiPMs) are an excellent candidate for thedevelopment of large-area light sensors. Large SiPM-based detectors requirelow-noise pre-amplifiers to maximize the signal coupling between the sensor andthe readout electronics. This article reports on the development of a low-noisetransimpedance amplifier sensitive to single-photon signals at cryogenictemperature. The amplifier is used to readout a 1 cm$^{2}$ SiPM with a signalto noise ratio in excess of 40.
