Detecting fast and thermal neutrons with a boron loaded liquid scintillator, EJ-339A

A commercial boron-loaded liquid scintillator EJ-339 A was studied, using a Cf-252 source with/without polyethylene moderator, to examine the possibility of discriminating slow-neutron induced events in B-10 from fast-neutron events, resulting from proton recoils, and gamma-ray events. Despite the strong light quenching associated with neutron induced events in B-10, correct classification of these events is shown to be possible with the aid of digital signal processing.
