Figure 4

Energy spectra of one phoswich detector in end-on (left) and side-on (center) irradiation. The dash line in the figures indicates the energy threshold (0.22 V) for selecting events in the photopeaks. (Right) Layer-deconvolved energy spectrum for photopeak events acquired in end-on irradiation. Each event was assigned to either LYSO or LSO layer based on its ToT value (figure 5, left).
