Title: Characterization of a 6Li-loaded liquid organic scintillator for fast neutron spectrometry and thermal neutron detection
Published: March 24, 2013
Abstract: We present the characterization of a liquid scintillator incorporating an aqueous solution of enriched lithium chloride to produce a scintillator with 0.40% 6Li. We report on its performance in terms of optical properties and neutron response. We incorporated the scintillator into a cell and measured the light output spectra from 2.5 MeV, 14 MeV, and Cf-252 neutrons using capture-gated coincidence techniques. We operated the spectrometer without coincidence to perform thermal neutron measurements. We discuss of possible improvements in spectrometer performance.
