During the SiPM irradiation tests, Hamamatsu S12572-010P was chosen as the best available candidate for the PSD readout. Dark current increase with the absorbed fluence raises the requirement for the corresponding highcurrent power supply up to 1 mA per SiPM (channel). Gradual degradation of the SiPM signal to noise ratio with the absorbed fluence poses the requirement for the regular PSD module recalibration during the experiment operation.
PSD energy resolution R_E studied at NA61 beamtime dropped only slightly - by 4.6 % for the SiPMs irradiated by total fluence of 4E11 n/cm2.
