Liquid xenon and liquid argon detectors are leading the direct dark matter search and are expected to be the candidate technology for the forthcoming generation of ultra-sensitive large-mass ...detectors. At present, scintillation light detection in those experiments is based on ultra-pure low-noise photo-multipliers. To overcome the issues in terms of the extreme radio-purity, costs, and technological feasibility of the future dark matter experiments, the novel silicon photomultiplier (SiPM)-based photodetector modules seem to be promising candidates, capable of replacing the present light detection technology. However, the intrinsic features of SiPMs may limit the present expectations. In particular, interfering phenomena, especially related to the optical correlated noise, can degrade the energy and pulse shape resolutions. As a consequence, the projected sensitivity of the future detectors has to be reconsidered accordingly.

We report on the characterization of near-ultraviolet high-density silicon photomultiplier (SiPM) developed at Fondazione Bruno Kessler (FBK) at cryogenic temperature. A dedicated setup was built to ...measure the primary dark noise and correlated noise of the SiPMs between 40 and 300 K. Moreover, an analysis program and data acquisition system were developed to allow the precise characterization of these parameters, some of which can vary up to seven orders of magnitude between room temperature and 40 K. We demonstrate that it is possible to operate the FBK near-ultraviolet high density SiPMs at temperatures lower than 100 K with a dark rate below 0.01 cps/mm 2 and total correlated noise probability below 35% at an overvoltage of 6 V. These results are relevant for the development of future cryogenic particle detectors using SiPMs as photosensors.
Silicon photomultipliers (SiPMs) are an excellent candidate for the development of large-area light sensors. Large SiPM-based detectors require low-noise preamplifiers to maximize the signal coupling ...between the sensor and the read-out electronics. This paper reports on the development of a low-noise transimpedance amplifier sensitive to single-photon signals at cryogenic temperature. The amplifier is used to read-out a 1-cm 2 SiPM with a signal-to-noise ratio in excess of 40.
We report on the realization of a novel silicon photomultiplier (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 Hz/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.

Detection of light signals is crucial to a wide range of particle detectors. In particular, efficient detection of vacuum ultraviolet (VUV) light will provide new opportunities for some novel ...detectors currently being developed, but is technically challenging. In this article, we characterized the performance of Hamamatsu VUV4 silicon photomultipliers (SiPMs) for detecting VUV argon scintillation light without wavelength shifting. Using a customized cryogenic amplifier design, we operated two models of VUV4 SiPMs inside liquid argon and thoroughly examined their direct sensitivities to liquid argon scintillation. In addition to describing their cryogenic performance, we measured a photon detection efficiency of \(14.7^{+1.1}_{-2.4}\)% and \(17.2^{+1.6}_{-3.0}\)% at 128 nm for these two VUV4 models for operation at 4 V of overvoltage, with the main uncertainty arising from the SiPM reflectivity for VUV light.
