【 摘 要 】

This paper presents an experimental approach to determine the neutron and gamma ray thresholds in fast, organic scintillating detectors. Neutron threshold energy is determined using a time-of-flight technique, while gamma ray threshold is inferred by locating the Compton edge for various reference gamma sources. These energy thresholds are then related to the Constant Fraction Discriminator (CFD) levels used in these experiments.
