摘要
基于蒙特卡罗模拟思想,利用虚拟仪器开发工具LabWindows/CVI编制软件模拟了γ光子在NaI(T1)闪烁晶体中的输运过程。直接以γ光子在NaI(T1)闪烁晶体中的沉积能量近似对应实际γ能谱仪的脉冲幅度输出.从而得到NaI(T1)探测器中γ射线的响应谱线。结果表明,蒙特卡罗模拟得到的能谱能较好地拟合实验测量得到的能谱。
a computer procedure was organized to simulate the process of transportation for the γ photon in the NaI（Tl） scintillation crystal based on LabWindows/CVI and the idea of Monte Carlo simulation. The γ energy spectrums in NaI（Tl） crystal detector are obtained by establishing a correlation between the deposit energy of γ photon and the output of pulse amplitude. The results show that the simulating spectrum can resemble the measuring spectrum precisely.
