Abstract

Prototype of gamma ray detector based on Micro Pixel Avalanche Photodiodes (MAPD) with high pixel density 15000 pixel/$mm^2$, 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.
