在达雷斯伯里实验室的受激喇曼散射同步辐射光源上，利用2 T多极扭摆器的输出，建立了一条XUV光束线。束线基于SGM设计，并产生能量范围为40-350 eV的光子。通过采用7.5 mrad风扇，可以提供1 × 1013和1 × 1014光子/s/300 mA环电流之间的高通量，分辨率约为1000。一对柯克帕特里克-贝兹镜将光线聚焦到单色器的入口狭缝上。使用10 · m的入口和出口狭缝，可以实现高达10，000的分辨率，通量为0.5-2 × 1011光子/s/300 mA。计算和测量的性能，强调与利用高场MPW源的XUV输出相关联的挑战。此外，还概述了科学研究方案。
An XUV beamline has been constructed on the SRS synchrotron radiation source at Daresbury Laboratory, exploiting the output from a 2 T multi-pole wiggler. The beamline is based on an SGM design and produces photons in the energy range 40–350 eV. By taking a 7.5 mrad fan, a high flux of between 1 × 1013 and 1 × 1014 photons/s/300 mA ring current can be delivered, with a resolving power of around 1000. A Kirkpatrick–Baez mirror pair focuses the light onto the entrance slit of the monochromator. Using 10 · m entrance and exit slits, a resolving power of up to 10,000 can be achieved, with a flux of 0.5–2 × 1011 photons/s/300 mA. The calculated and measured performance is presented, with emphasis on the challenges associated with utilizing the XUV output of a high field MPW source. In addition, the scientific research programme is outlined.
