source at 75 cm distance and a 137Cs source producing 30.16 μR/h at 30 cm distance. (b) The distribution of PSD parameter at various energies (300 ± 100 keVee, 500 ± 100 keVee, 700 ± 100 keVee) for the overall detector PSD plot. (c) The PSD plot that one of the pixels has and (d) the corresponding FOM values for the aforementioned three cases.

(a) The overall detector PSD plot for 1,500,000 pulses produced by the stilbene-SiPM module with a threshold of 50 keVee by measuring a 3.5 × 105 n/s 252Cf spontaneous fission
