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.
介绍了位于钻石光源多功能软X射线（VersoX）光束线B07的B分支处的光束线光学元件和终端站。B07-B从弯曲磁铁源提供45-2200 eV范围内的中通量X射线，可用于研究从锂到钇的所有元素原子的局部电子结构。它有一个终端站，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有第二个终端站，用于在从超高真空到环境压力（1 atm）的压力下进行NEXAFS测量。这些终端站的组合允许研究广泛的界面和材料。详细讨论了光束线和终端站的设计，以及它们的性能和调试过程。
