| Abstract | We report on the energy, timing, and pulse-shape discrimination performance of cylindrical 5 cm diameter x 5 cm thick and 7 cm diameter x 7 cm thick {\it trans}-stilbene crystals read out with the passively summed output of three different commercial silicon photo-multiplier arrays. Our results indicate that using the summed output of an 8x8 array of SiPMs provides performance competitive with photo-multiplier tubes for many neutron imaging and correlated particle measurements: for the 5x5 cm crystal read out with SensL's ArrayJ-60035\_64P-PCB, which had the best overall properties, we measure the energy resolution as 13.6$\pm$1.8\% at 341 keVee, the timing resolution in the 100--400 keVee range as 277$\pm$34 ps, and the pulse-shape discrimination figure-of-merit as 2.21$\pm$0.03 in the 230--260 keVee energy range. These results enable many scintillator-based instruments to enjoy the size, robustness, and power benefits of silicon photo-multiplier arrays as replacement for the photo-multiplier tubes that are predominantly used today. |
