Abstract

A soft x-ray monochromator was developed for synchrotron radiation and installed at the Photon Factory in the National Laboratory for High Energy Physics. This monochromator consists of only two optical elements: a plane mirror and a varied-space plane grating with focusing properties. The 0.7-10-nm wavelength range can be covered with resolutions of 640 at 1.4 nm and 1200 at 5 nm. The output photon flux at wavelengths above 1 nm is ~10(10)-10(11) photons/s for a 100-mA beam current in the 1% spectral bandwidth.

摘要

一种用于同步辐射的软X射线单色仪已研制成功，并安装在高能物理国家实验室的光子工厂。该单色仪仅由两个光学元件组成：一个平面镜和一个具有聚焦特性的变间距平面光栅。其波长范围为0.7 - 10纳米，在1.4纳米处分辨率为640，在5纳米处分辨率为1200。对于100毫安的束流，在1%光谱带宽下，波长大于1纳米时的输出光子通量约为10(10)-10(11) 光子/秒。
