Abstract
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 40% organic glass scintillator and 60% polystyrene. We tested a cylindrical sample with dimensions of 2x2 inches. The study includes measurements of neutron-gamma discrimination capability, emission spectra, photoelectron yield, and the 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), an EJ-309 liquid scintillator, and EJ-276 and M600 polyurethane-based plastic scintillators.
