Measurement of the response of a liquid scintillation detector to monoenergetic electrons and neutrons

摘要

The response of the liquid scintillator (EJ-301 equivalent to NE-213) to themonoenergetic electrons produced in Compton scattered $\gamma$-ray tagging hasbeen carried out for various radioactive $\gamma$-ray sources. The measuredelectron response is found to be linear up to $\sim$4~MeVee and the resolutionof the liquid scintillator at 1~MeVee is observed to be $\sim$~11\%. The pulseshape discrimination and pulse height response of the liquid scintillator forneutrons has been measured using $^7$Li(p,n$_1$)$^7$Be*(0.429 MeV) reaction.Non linear response to mono-energetic neutrons for the liquid scintillator isobserved at E$_n$=5.3, 9.0 and 12.7 MeV. The measured response of the liquidscintillator for electrons and neutrons have been compared with Geant4simulation.
