Abstract

The beamline optics and endstations at branch B of the Versatile Soft X-ray (VerSoX) beamline B07 at Diamond Light Source are described. B07-B provides medium-flux X-rays in the range 45-2200 eV from a bending magnet source, giving access to local electronic structure for atoms of all elements from Li to Y. It has an endstation for high-throughput X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine-structure (NEXAFS) measurements under ultrahigh-vacuum (UHV) conditions. B07-B has a second endstation dedicated to NEXAFS at pressures from UHV to ambient pressure (1 atm). The combination of these endstations permits studies of a wide range of interfaces and materials. The beamline and endstation designs are discussed in detail, as well as their performance and the commissioning process.

VerSoX B07-B：钻石光源的高通量 XPS 和常压 NEXAFS 光束线。

本文介绍了钻石光源多功能软 X 射线（VerSoX）光束线 B07 分支 B 的光束线光学系统和终端站。B07-B 通过一个弯曲磁源提供 45-2200 eV 范围内的中等通量 X 射线，可以获得从 Li 到 Y 所有元素原子的局部电子结构。它有一个端站，用于在超高真空（UHV）条件下进行高通量 X 射线光电子能谱（XPS）和近边 X 射线吸收精细结构（NEXAFS）测量。B07-B 还有一个专门用于在超高真空到环境压力（1 atm）条件下进行近边缘 X 射线吸收精细结构（NEXAFS）测量的终端站。这些终端站的组合可以对各种界面和材料进行研究。本文详细讨论了光束线和终端站的设计、性能和调试过程。
