摘要: 采用自主研发的JMCT软件,模拟计算了γ射线在NaI闪烁探测器中的响应函数。JMCT模拟计算了探测过程中所有的、完整的光子-电子耦合输运过程。其模拟计算的γ射线能量沉积谱、探测器响应函数,与 MCNP的计算结果符合得非常好,与 Berger 解析法计算的结果也基本符合,表明 JMCT 软件可以在探测器响应函数方面得到满意的结果,JMCT将在实验核物理、核分析技术应用等方面发挥越来越重要的作用。Abstract: The JMCT software is used to calculate the gamma-ray response functions for NaI crystal.The complete process of all the photon-electron coupled transportation is simulated by JMCT.The gamma-ray energy deposition spectrum and detector response functions are obtained and discussed.It is found that the results calculated by JMCT are the same as the results calculat-ed by MCNP,and correspond well to the results calculated by Berger,which shows that the detector response functions simulated by JMCT are correct and satisfying.JMCT will play a more and more important role in the field of the experimental nuclear phys-ics and nuclear analysis technology.
