Calibration Technique for Stilbene-Based Neutron Detector

Abstract

Fast neutron detection requires application of the detector material that is rich in hydrogen with a sufficient level of detection efficiency and the capability to discriminate neutron signals in the presence of undesirable gamma-ray background. In this work, we evaluated the performance of neutron modules with the measurement of gamma-sources. In particular, the light yield of the detectors was calibrated with a set of standard ²²Na, ¹³⁷Cs and ²⁴¹Am sources by the use of Compton Edge technique. In the meanwhile, the time resolution was estimated by measuring gamma-gamma coincidences with ⁶⁰Co source.
