Description

Many improvements in SiPM production technology have been achieved in the last few years. Using SiPM as a photodetector is one option for the next TOP detector upgrade of the Belle II experiment. The characterization of SiPMs from several producers is ongoing at the INFN/University Padova laboratory at different temperatures down to -40 degrees. The selected SiPMs are the last available generation with 1x1 mm2 and 3x3 mm2 dimensions and different cell sizes from different producers. Eight 1x1 mm2 SiPMs have been irradiated in November 2022 at INFN-LNL, additional 3x3 mm2 SiPMs will be irradiated in July 2023. The degradation of the SiPMs characteristics has been measured for different irradiation levels up to 5x10^11 neutrons/cm2. Plans for SiPM development in collaboration with FBK have been included in the AIDAinnova project together with the JSI Ljubliana institute, and inside a Research Project (PRIN) submitted to the Italian Ministry of Research.
