Performance of a Thin Layer of Plastic Scintillator Material to be Used as a Charged Particle Detector Using Geant4

Abstract

Abstract: The performance of a thin layer of plastic scintillator is investigated for use as a charged particle detector in various applications, including neutron-induced reactions with a charged particle in the exit channel. The detection efficiency for alpha particles and background radiation, including γ-radiation, electrons, and neutrons, was investigated using the Geant4 simulation toolkit. The results show that a thin layer of plastic scintillator can measure the alpha particles with a high efficiency of 50% for isotropic sources while keeping background radiation (with a very low detection efficiency) below 10%.
