摘要：Monte Carlo software MCNPX was used to simulate the influence of geometric factors and doping concentration of CLYC-6 scintillator detector on detection efficiency and luminous efficiency. It is found that with the increase of CLYC-6 crystal size, the detection efficiency increases nonlinearly, while the luminous efficiency decreases nonlinearly, and the changing trend of both decreases with the increase of crystal size. Under different particle radiation energies, the thickness of the CLYC-6 crystal is 2.54 cm, the bottom diameter is 17.78 cm, and the doping concentration (Ce3+) is 0.5%. The luminescence efficiency reaches the maximum value, and it has good detection efficiency. This result can provide a reference for the development of the CLYC-6 detector.
