Abstract

Polyvinyl Toluene (PVT) based plastic scintillators with varying dimensions and fluors have been characterized in terms of relative light output and spatial resolution. Scintillators were exposed to fast neutrons (∼2 MeV), and images were obtained with a setup consisting of an EMCCD camera, a mirror and a light-tight apparatus. Among scintillators with 2.0% Flrpic and 10.16 cm (4 inch) diameter, the 10.5-mm thick scintillator featured the highest light output while 3.0- mm provided the best spatial resolution. The deuterated 3.0-mm thick scintillator doped with 2.0% Flrpic showed a worse performance in terms of both light output and spatial resolution compared to that of undeuterated scintillator with the same thickness but doped with 2.0% X-Flrpic. This study reveals the effects of presence of deuterium in PVT, the thickness of scintillator, and the fluor on the light output and spatial resolution of plastic scintillator.
