Abstract

This paper presents the results of the proton irradiation of silicon photomulipliers (SiPMs) by mono-energetic 170 MeV protons with fluence up to 4.6 $\times$ 10 $^{9}$ particles/cm $^2$ . In our work, three types of silicon photodetectors from Hamamatsu with areas 3 $\times$ 3 mm $^2$ and different subpixel sizes of 25 $\times$ 25 $\mu$ m $^2$ , 50 $\times$ 50 $\mu$ m $^2$ , and 75 $\times$ 75 $\mu$ m $^2$ were used. The changes in the SiPM dark count rate (DCR) spectrum before and after irradiation in temperatures in the range of 20 $^\circ$ C to -65 $^\circ$ C are presented. The influence of the DCR changes on the energy resolution of the 662 keV gamma line from the $^{137}$ Cs for a non-irradiated GAGG:Ce (1 $\%$ ) scintillator is investigated. The time period of usability of the SiPM detector irradiated by protons in cosmic space was estimated.
