摘要: 主要论述一个用于多层不均匀厚靶μ-PIXE分析谱的模拟的计算机软件。该软件用C语言编写而成、有较好的用户界面窗口、操作方便。该软件可对样品根据其层数和所包含的包裹的数目及形状进行定义,可完成二维和线扫描的X射线强度分布的计算。给出了对铜网格的模拟计算及与实验结果比较,并给出了对一简单包裹体的模拟结果。该软件还可用于厚靶微米PIXE的定量分析。

Abstract: A computer program is developed for simulation of μ-PIXE spectra for multi-layer and inhomogeneous thick target analysis. The program can allow users to define three dimensions multi-layer and inhomogeneous target in terms of slices and inclusions. Computations of 2D maps and line scan distribution have been performed on a target consisting of a spherical Fe inclusion embedded in a Si block. The Cu mesh is also used to test the program. The line scan result agress well with that obtained from experiment

Key words: Multi-layer, Inhomogeous, Thick target, μ-PIXE, Simulation
