【 摘 要 】

We measured the performance of a 2"2" tapered cylindrical SrI2:Eu, a 2" 3" cylindrical CeBr3, a 2" 0.3" cylindrical GYGAG:Ce. The gamma-ray energy resolution was measured up to 9 MeV. A scan along three axes of each scintillator was performed using a collimated source of137Cs. The signals of the detectors were also digitized and compared. We tested two 1" 1" cylindrical CLYC crystals. One was enriched with6Li at 95% while the other was enriched with 99% of7Li. The response of the two detectors to gamma rays, thermal and fast neutrons was measured. The PSD performances have been tested with a different types of PMTs.
