Abstract

The characterization of the photon energy resolution of a liquid scintillation detector is desirable for simulating photon pulse height distributions in Monte Carlo codes such as MCNPX-PoliMi. Previous studies in literature determined a function characterizing the photon energy resolution for four photon detectors using the wide-angle Compton coincidence technique. The goal of this work is to utilize this technique to measure the photon resolution for the EJ-309 organic scintillation detector. The photon energy resolution was measured for an EJ-309 organic scintillation detector using a high-purity germanium (HPGe) detector and a 100-μCi ¹³⁷Cs source. The photon energy resolution of the EJ-309 was measured to be between 16 and 28% for photon energies between 390 and 280 keV.
