Comparison of an OGS/Polystyrene scintillator (BSO-406) with pure OGS (BSO-100), EJ-276, EJ-309, and M600 scintillators

In this paper, we present an investigation into the scintillation properties and pulse shape discrimination (PSD) performance of the new BSO-406, which is a blend of organic glass scintillator and 60% polystyrene. We tested a cylindrical sample with dimensions of 2 × 2 inches. The study includes measurements of neutron-gamma discrimination capability, emission spectra, photoelectron yield, and analysis of light pulse shapes originating from events related to gamma-rays and fast neutrons. The results were compared to data previously recorded using a pure Organic Glass Scintillator (BSO-100), EJ-276 plastic scintillator, an EJ-309 liquid scintillator, and an M600 polyurethane-based plastic scintillator.
