Abstract
In this paper, we report on the scintillation properties and pulse shape discrimination (PSD) performance of new plastic scintillators, EJ-276 and EJ-276G . Cylindrical samples with dimensions of 1×1 inch and 2×2 inches were tested. Additionally, four samples 2×2 inches in size were used in stack configurations in order to measure the PSD characteristics of large samples (up to 2×8 inches). The paper covers the measurements of neutron/gamma discrimination, emission spectra, photoelectron yield, and analysis of the light pulse shapes originating from events related to gamma-rays and fast neutrons. The results were compared to data recorded previously using plastic scintillators EJ-299-33, EJ-299-33G, EJ-299-34, EJ-299-34G, and an EJ-301 liquid scintillator.
