In this project, we have measured and studied the pulse shapes of signals originating from inorganic scintillators
coupled to Silicon Photomultipliers for a varying temperature. In particular, we performed measurements for
CsI, NaI, CeBr3 and CLYC scintillating crystals. The measurements took place inside a controlled atmosphere
station that allowed handling of the bare hygroscopic crystals. The temperature was controlled by Peltier
element. The analysis was carried out using a simple pulse shape analysis method based on the ratio of two
different integration regions. The results show that in most cases this simple method is adequate to capture the
change in the signal pulse shapes caused by the temperature changes.
