Characterization of AdvanSiD and hamamatsu SiPMs for novel design cryogenic detectors

Silicon Photomultipliers are semiconductor-based photodetectors with performances similar to the traditional photomultiplier tubes, frequently used in many fields. In this article we report results obtained testing some devices at cryogenic temperatures in view of an application for scintillation light detection in detectors that use liquid argon as active medium. This campaign of measurements is the first step to find the most suitable model for this application.
