The aim of this work is to provide the characteristics of two samples of Fondazione Bruno Kessler (FBK) high-density SiPMs with an active area of 2.2 × 2.2 mm2 (15 × 15 μm2 single cell size) and 4 × 4 mm2 (30 × 30 μm2 single cell size) in gamma-ray spectrometry with LSO and CsI:Tl scintillators. The measurements presented in this work covered: measurements of spectra with low number of detected photons (one to a few fired APD cells), characteristics of the breakdown voltage versus temperature, verification of the excess noise factor, selection of the optimum operating voltage for energy resolution, verification of the linearity of the SiPM response for both used scintillators, verification of the number of fired APD cells and gamma-ray spectrometry for a wide range of X and gamma ray energies from 22.1 to 1408 keV.

Abstract

The aim of this work is to provide the characteristics of two samples of Fondazione Bruno Kessler (FBK) high-density SiPMs with an active area of 2.2 × 2.2 mm2 (15 × 15 μm2 single cell size) and 4 × 4 mm2 (30 × 30 μm2 single cell size) in gamma-ray spectrometry with LSO and CsI:Tl scintillators. The measurements presented in this work covered: measurements of spectra with low number of detected photons (one to a few fired APD cells), characteristics of the breakdown voltage versus temperature, verification of the excess noise factor, selection of the optimum operating voltage for energy resolution, verification of the linearity of the SiPM response for both used scintillators, verification of the number of fired APD cells and gamma-ray spectrometry for a wide range of X and gamma ray energies from 22.1 to 1408 keV.
