Alpha particle detector based on micro pixel avalanche photodiodes

Abstract

The main goal of this work is a study of possibility to detect alpha particles by micro-pixel avalanche photodiode (MAPD) which has very thin active volume (4 μ m) and by micro-pixel avalanche photodiode in combination with Lutetium Fine Silicate (LFS) scintillators (500 μ m thickness). The obtained results show that alpha detectors based on MAPD are expected to be useful in many applications: public security (Associated Particle Imaging for explosives and drugs detection), radioactive contamination monitoring in various environments and detection of charged particles from nuclear reactions.
