摘要
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。
VerSoX B07-B: a high-throughput XPS and ambient pressure NEXAFS beamline at Diamond Light Source.
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.
