Abstract
- Organic glass scintillator (OGS) bars (6 × 6 × 50 mm 3) were melt-cast and characterized with dual-ended readout by silicon photomultiplier arrays. The results were compared to trans -stilbene bars of the same size. Energy resolution was measured via a 137Cs Compton-coincidence experiment. Time resolution was determined via a 22Na coincidence-timing experiment. Depth-of-interaction resolution was measured by moving a gamma-ray fan beam along the major axis of the bars. Pulse shape discrimination capability and neutron light output were determined via a time-of-flight measurement of a 252Cf source. The OGS bars exhibited better energy resolution at 478 keV (10. 3 ± 0. 5 % vs. 11. 2 ± 0. 5 %), better time resolution from 200–341 keVee (270 ps vs. 340 ps FWHM), slightly poorer depth-of-interaction resolution, poorer PSD performance, and higher neutron light output than the stilbene bars. The low cost, ease of manufacturing, brightness, and excellent time resolution make OGS a strong candidate for use in compact radiation imaging systems. [ABSTRACT FROM AUTHOR]
