The design and performance of the microfocus spectroscopy beamline at the Diamond Light Source are described. The beamline is based on a 27 mm-period undulator to give an operable energy range between 2 and 20.7 keV, enabling it to cover the K-edges of the elements from P to Mo and the L(3)-edges from Sr to Pu. Micro-X-ray fluorescence, micro-EXAFS and micro-X-ray diffraction have all been achieved on the beamline with a spot size of approximately 3 microm. The principal optical elements of the beamline consist of a toroid mirror, a liquid-nitrogen-cooled double-crystal monochromator and a pair of bimorph Kirkpatrick-Baez mirrors. The performance of the optics is compared with theoretical values and a few of the early experimental results are summarized.
描述了英国钻石光源微聚焦光谱学光束线的设计和性能。该光束线基于一个 27mm 周期的波荡器，可提供 2 到 20.7keV 的工作能量范围，从而能够涵盖从 P 到 Mo 的元素的 K 边和从 Sr 到 Pu 的 L(3)-边。在该光束线上已经实现了微 X 射线荧光、微 EXAFS 和微 X 射线衍射，光斑大小约为 3 微米。该光束线的主要光学元件包括一个环形镜、一个液氦冷却的双晶单色仪和一对双折射 Kirkpatrick-Baez 反射镜。对光学元件的性能与理论值进行了比较，并总结了一些早期的实验结果。
