摘要

为了扩大x射线测试光束线的覆盖能量范围，在上海同步辐射设施设计并制造了一种恒定成像距离固定夹角光栅单色仪。本文介绍了该系统的设计和首次调试结果。初步结果表明，该单色仪性能良好，高线密度光栅在氪m边缘的光子能量分辨能力估计超过8000，低线密度光栅的-1级衍射效率优于30%。

Optical design and commissioning results of a constant-imaging-distance fixed-included-angle grating monochromator at SSRF.

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.
