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.

DarkSide is a graded experimental project based on radiopure argon, and is now, and will be, used in direct dark matter searches. The present DarkSide-50 detector, operating at the Gran Sasso ...National Laboratory, is a dual-phase, 50 kg, liquid argon time-projection-chamber surrounded by an active liquid scintillator veto. It is designed to be background free in 3 years of operation. DS-50 performances, when filled with atmospheric argon, are reported. However DS-50 filled with underground argon, shows impressive reduction of the 39Ar isotope. The application of this powerful technology in a future generation of the DarkSide program is discussed.
Future dark matter direct detection experiments will reach unprecedented levels of sensitivity. Achieving this sensitivity will require more precise models of signal and background rates in future ...detectors. Improving the precision of signal and background modeling goes hand-in-hand with novel calibration techniques that can probe rare processes and lower threshold detector response. The goal of this white paper is to outline community needs to meet the background and calibration requirements of next-generation dark matter direct detection experiments.
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 cm\(^{2}\) SiPM with a signal to noise ratio in excess of 40.
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.
