Abstract

Excerpt: Fieldable instruments can encounter a variety of environments during their use. A recent fieldable fast neutron spectrometer, nSpec, has been exploring alternate materials for further ruggedizing the system. One of these materials, EJ276D, is a plastic scintillator which provides several benefits over the current liquid scintillators used in nSpec, including an operating temperature range that is more closely matched to the limits of the electronics in the system. In the following work, the temperature dependence of EJ276D is studied from -10 to 50 °C. The temperature dependence of the calibration and resolution of the detector were characterized using basic gamma-ray sources, while the characterization of the light output quenching for neutron interactions was done utilizing the Los Alamos Neutron Science Center (LANSCE).
