Characterization Of New Scintillators: Sri2:Eu, Cebr3, Gygag:Ce And Clyc:Ce

We measured the performance of a 2 '' x2 '' tapered cylindrical SrI2:Eu, a 2 '' x 3 '' cylindrical CeBr3, a 2 '' x 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 of Cs-137. The signals of the detectors were also digitized and compared. We tested two 1 '' x 1 '' cylindrical CLYC crystals. One was enriched with Li-6 at 95% while the other was enriched with 99% of Li-7. 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.
