Development of a very low-noise cryogenic pre-amplifier for large-area SiPM devices
Abstract
Silicon Photomultipliers (SiPMs) are an excellent candidate for the development of large-area light sensors. Large SiPM-based detectors require low-noise pre-amplifiers to maximize the signal coupling between the sensor and the readout electronics. This article reports on the development of a low-noise transimpedance amplifier sensitive to single-photon signals at cryogenic temperature. The amplifier is used to readout a 1 cm2 SiPM with a signal to noise ratio in excess of 40.
