Investigation of gamma ray detection performance of thin LFS scintillator with MAPD readout

Abstract

Prototype of gamma ray detector based on Micro Pixel Avalanche Photodiodes (MAPD) with high pixel density 15000 pixel/$m{m}^2$, optically coupled to Lutetium Fine Silicate (LFS) scintillator has been developed. The detection performance investigated in the range of energy 59.6 - 662 keV at room temperature. The results of measurements are presented in this work.
