“…In addition, phoswich detectors, consisting of multiple layers of different scintillators, produce different pulse shapes depending on which layer absorbs the radiation, which can be used for particle identification [2,3,4]. Consequently, many materials and PSA algorithms have been proposed and studied in this context for many years [5,6,7,8,9,10]. Overall, the PSD tends to depend more on the choice of scintillator than the PSA algorithms, many of which produce similar figures of merit (FOM) [11,12], though processing complexity can vary widely.…”
