Abstract
Silicon photomultipliers (SiPMs) are compact solid state photodetectors having single photoelectron (PE) level sensitivity. Due to their attributes, they are being considered for the photo detection systems of future neutrino detectors. Consequently, comprehensive studies of SiPMs at cryogenic temperatures are required since the data provided by the manufactures do not cover this temperature regime. In this work, SiPMs are tested for proper operation in a cryostat for the expected lifetime of the future experiments. The characterization of SenSL C-series SiPMs and their long-term mechanical durability are discussed. Performance of SiPMs from other vendors are also discussed.
