摘要：

The aim of this work is characterization of MPPC arrays with active area of 6x6 mm in gamma-ray spectrometry with four scintillators CsI(Tl), LSO: Ce(Ca), LaBr3 and BGO. The chosen scintillators have significantly different decay times of a scintillation pulse and different wavelength of emission peaks. It allowed study of the influence of MPPC effective dead time on a device response and calculation of a Photon Detection Efficiency (PDE) of MPPC. The measurements covered: a selection of the optimum operating voltage, a verification of the linearity range for a given decay time of the crystals, a verification of the excess noise factor for the optimal voltage and calculation of the PDE of MPPC. Measurements of energy resolution and nonproportionality obtained with the MPPC arrays and CsI(Tl) or BGO were compared to the similar measurements performed with XP2020Q PMT.
