Cesium iodine crystals can be divided into three types based on the do pant, CsI(Tl), CsI(Na) and pure CsI. All of them are colorless transparent cubic crystals. CsI(Tl) is the most typical alkali halide scintillation crystal apart from NaI(Tl). Its light output is *5% of that in NaI(Tl). Its emission spectrum has a broad band at ******0nm and a peak at **0nm. Its emission spectrum can match well with SPD so that the read out system can be simplified. Due to the decay time is dependent on the ionization capacity of a particle, it is suitable to detect heavy charged particles under strong g-ray background.
