Abstract

A constant-imaging-distance fixed-included-angle grating monochromator has been designed and constructed at the Shanghai Synchrotron Radiation Facility to expand the covered energy range of the X-ray test beamline. The design and first commissioning results are presented in this paper. Initial results reveal the good performance of this monochromator, with a photon energy resolving power estimated to be over 8000 at the krypton M-edge for high line density gratings and a -1st order diffraction efficiency of the grating better than 30% for low line density gratings.

摘要

为了扩大X射线测试光束线的覆盖能量范围，在上海同步辐射装置设计并建造了一种成像距离固定、夹角固定的光栅单色仪。本文介绍了该单色仪的设计和首次调试结果。初步结果表明该单色仪性能良好，对于高线密度光栅，在氪M边处光子能量分辨能力估计超过8000，对于低线密度光栅，光栅的一阶衍射效率优于30%。
