Comparison of energy spectra measured from the fast output and standard output using one single 6 × 6 mm2 SiPM and 3.34 × 3.34 × 20 mm3 LYSO wrapped with several layers of Teflon. The bias voltage was 28.0 V and the temperature was 5 °C . The energy resolution was 9.2 ± 0.3 % (fast output) and 8.5 ± 0.1 % (standard output) without saturation correction.
