In this paper is worked on the dependence of response function of CsI (Tl) scintillator on temperature gradient . In fact , the cooling effects for temperature range from -30 ℃ to 30 ℃ on the output pulse shape and resolution of this detector is studied, which it diameter and length are 40 mm and 120 mm , respectively , and also , the coupled photomultiplier with this scintillator has 40 mm and 50 mm diameter and length, respectively. The generated results under 670V, which is the best voltage that we measured for this scintillator in the room temperature , and in this mentioned temperature range , demonstrate the linear reduction treatment for this scintillator and so for temperature range from +30℃ to -30℃ , the energy resolution of this scintillator has changed from 0.2169 to 0.3238 , so we can conclude that energy resolution reduced by 50 % .
