Abstract

Multilayer gratings are increasingly popular optical elements at X-ray beamlines, as they can provide much higher photon flux in the tender X-ray range compared with traditional single-layer coated gratings. While there are several proprietary software tools that provide the functionality to simulate the efficiencies of such gratings, until now the X-ray community has lacked an open-source alternative. Here MLgrating is presented, a program for simulating the efficiencies of both multilayer gratings and single-layer coated gratings for X-ray applications. MLgrating is benchmarked by comparing its output with that of other software tools and plans are discussed for how the program could be extended in the future.

摘要

多层光栅在X射线光束线中越来越成为受欢迎的光学元件，因为与传统的单层镀膜光栅相比，它们在软X射线范围内可以提供高得多的光子通量。虽然有几种专有软件工具提供了模拟此类光栅效率的功能，但到目前为止，X射线领域一直缺乏开源的替代方案。本文介绍了MLgrating，这是一个用于模拟X射线应用中多层光栅和单层镀膜光栅效率的程序。通过将其输出与其他软件工具的输出进行比较，对MLgrating进行了基准测试，并讨论了该程序未来如何扩展的计划。
