摘　　要：根据同步辐射光源对软X射线分光晶体的性能要求,分析了软X射线能区常用分光晶体的性能优劣,指出对于晶格常数值大的分光晶体,KTP(KTiOPO4)(011)是该能区比较理想的分光晶体.同时提出了一种利用同步辐射光源测量晶体衍射效率的实验方法,指出光源的发散度与晶体的衍射效率密切相关.测量了KTP(011)晶体的晶格常数,给出了KTP(011)晶体的实测衍射效率.According to the requirements for the performance of analyzers in soft x-ray regime of synchrotron radiation,the qualities of various crystals often used in soft x-ray range are investigated.We find that crystals KTP（KTiOPO4）（011） crystal is an ideal one among large d-spacing crystals.We propose an experimental method to measure diffraction efficiencies of crystals with synchrotron radiation source.In particular,we find that the diffraction efficiency is closely related to the source emittance.The lattice constant and diffraction efficiencies of KTP（011）crystal are also presented in this paper.
