| 摘 要： | 采用自主研发的JMCT软件,模拟计算了射线在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 calculated 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 physics and nuclear analysis technology. |
