X射线通过空心通道的传播：PolyCAD -射线跟踪代码（1）
X-ray propagation through hollow channel: PolyCAD - a ray tracing code (1)
摘要：
本文介绍了一个新的用于X射线光子跟踪的计算机辅助设计程序PolyCAD。为了理解PolyCAD代码及其结果，首先讨论了单个圆柱形通道（单毛细管）的X射线传输的理论基础。然后，最简单的情况下，圆柱形和圆锥形的多毛细管光学检查。PolyCAD允许使用任何类型的X射线源：有限束尺寸的X射线管或天体物理对象可以与多毛细管光学器件结合进行模拟。本文讨论了在不同焦距的荧光屏上形成的辐射分布图象。一些PolyCAD的结果与那些在早期的文件中报告的良好协议验证代码。这是一系列致力于开发详尽的CAD程序的第一篇论文，开发代码以包括其他多毛细管光学形状（如半透镜和全透镜）的工作正在进行中。
英文摘要：
A new CAD program, PolyCAD, designed for X-ray photon tracing in polycapillary optics is described. To understand the PolyCAD code and its results, the theoretical basis of X-ray transmission by a single cylindrical channel (monocapillary) is discussed first. Then the simplest cases of cylindrically and conically shaped polycapillary optics are examined. PolyCAD allows any type of X-ray source to be used: an X-ray tube of finite beam dimensions or an astrophysical object can be simulated in combination with the polycapillary optics. The radiation distribution images formed on a screen located at various focal distances are discussed. The good agreement of some of the PolyCAD results with those reported in earlier papers validate the code. This is the first paper of a series dedicated to the development of an exhaustive CAD program, work is in progress to develop the code to include other polycapillary-optics shapes, such as semi-lenses and full-lenses.
