Measured response of a liquid scintillation detector to quasi-monoenergetic electrons and neutrons

Abstract

The response of the liquid scintillator (EJ-301 equivalent to NE-213) to the monoenergetic electrons produced in Compton scattered γ-ray tagging has been carried out for various radioactive γ-ray sources. The measured electron response is found to be linear up to ∼4 MeVee and the resolution of the liquid scintillator at 1 MeVee is observed to be ∼ 11%. The pulse shape discrimination and pulse height response of the liquid scintillator for neutrons 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 is observed at E n =5. 3, 9.0 and 12.7 MeV. The measured response of the liquid scintillator for electrons and neutrons have been compared with Geant4 simulation.

“…The thresholds for all the three detectors were around 52.6 keV (D 1 ), 72.7 keV (D 2 ), and 70.6 keV (D 3 ) respectively. The intrinsic efficiency of the detectors D 1 , D 2 , and D 3 for 2.45 MeV neutrons was calculated to be around 42%, 40%, and 40%, respectively, using the GEANT4 [26] based Monte Carlo simulation for the corresponding threshold of a particular detector [27]. The pulse shape discrimination optimization was carried out using a 252 Cf source.…”
