The first domestic inorganic scintillator CLYC was grown in Beijing Glass Research Instituteusing the vertical Bridgman method. In this work, we evaluated the performance of this new CLYC crystal in terms of gamma-ray energy resolution and pulse shape discrimination(PSD)capability between neutrons and gamma-rays. The decay times occurred throughdifferent scintillation mechanisms were achievedby fitting decay functions to the neutron and gamma-ray waveform structures. We found an energy resolution of 4.5% for 662-keV gamma-rays and efficient neutron/gamma PSD withFoM 2.6. Under gamma-ray excitation, there is ultrafast scintillation mechanism in CLYC, with a decay time about 2 ns,whereasthere is no evidence of ultrafast decay under thermal neutron excitation. This work contributes to promote domestic development of CLYC.
