A schematic of the dual-ended-scintillator readout and experiment setup for DOI function measurement. An LYSO scintillator was read out by two SSPMs from two ends for the DOI function measurement with internal or external radiation. An external Na-22 point source was used for external radiation measurement. During external flood source measurements the TAC was bypassed and only the signals from the SSPM’s attached to the test crystal were digitized.
