Time-of-Flight Spectroscopy of 252Cf Spontaneous Fission Neutrons: Influences of Detector Voltage, Pulse-Shape Discrimination and Shielding
Experimental measurements to explore the effect of detector voltage, pulse-shape discrimination (PSD) threshold and detector shielding on time-of-flight measurements of the 252Cf neutron spectrum made with organic scintillation detectors are described. It is found that detector voltage has a major effect, whilst changing the PSD threshold and shielding the detectors to optimize sensitivity to the desired γ-neutron correlation results in a small effect.
