Description
It is reported on the study of radiation resistance of silicon photomultipliers (SiPM) produced by HAMAMATSU. SiPM was irradiated in neutron fluxes of the reactor IBR-2 of JINR. The tested SiPM received fluence from 1012 up to 2x1014 of neutrons/cm2. Irradiated detectors investigated using a radioactive source and laser flashes at a temperature of -300C. The measurements showed that the SiPM remain fully functional as photon detectors up to neutron fluence 2x1014 despite a significant increase in noise.
