The Monte Carlo program PENEPMA performs simulations of X-ray emission from samples bombarded with both electron and photon beams. It is based on the general-purpose Monte Carlo simulation package PENELOPE, an elaborate system for the simulation of coupled electron-photon transport in arbitrary materials, and on the geometry subroutine package PENGEOM, which tracks particles through complex material structures defined by quadric surfaces. After a brief description of the interaction models implemented in the simulation subroutines and of the structure and operation of PENEPMA, we provide an overview of the capabilities of the program along with several examples of its application to the modeling of electron probe microanalysis measurements.
蒙特卡罗程序PENEPMA可对被电子束和光子束轰击的样品的X射线发射进行模拟。它基于通用蒙特卡罗模拟软件包PENELOPE（一个用于模拟任意材料中电子 - 光子耦合输运的精密系统）以及几何子程序包PENGEOM（该程序包可追踪粒子通过由二次曲面定义的复杂材料结构）。在简要描述了模拟子程序中实现的相互作用模型以及PENEPMA的结构和操作之后，我们概述了该程序的功能，并给出了其在电子探针微分析测量建模应用中的几个示例。
