Characterization of VUV4 SiPM for Liquid Argon detector.

Particle detectors based on liquid argon are recently become recognized as an attractive technology for dark matter direct detection and coherent elastic neutrino-nucleus scattering measurement. A program using a dual-phase liquid argon detector with a fiducial mass of 200~kg to detect coherent elastic neutrino-nucleus scattering at Taishan Nuclear Power Plant has been proposed. SiPM will be used as the photon sensor because of its high radio-purity and high photon detection efficiency. S13370-6050CN SiPM, made by Hamamatsu, is an alternative for the detector. In this paper, the characterisation of S13370-6050CN SiPM, including the cross talk and after pulse probabilities at liquid argon temperature and the temperature dependence of break down voltage, dark count rate and relative quantum efficiency were presented.
