This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Development and commissioning have continued for a spectrometer based on multiple high resolution crystal analyzers for resonant inelastic x-ray scattering (RIXS), x-ray emission spectroscopy (XES) and advanced EXAFS. Currently the setup has six Si(553) analyzers (used for Cu K(beta) XES), three Ge(110) (in (440) order used for Fe 1s2p RIXS), three Ge(111) analyzers (in (333) order used for Mn 1s2p RIXS and range extended (RE) EXAFS, and in (444) order used for Zn K(beta) XES), three Ge(310) analyzers (in (620) order used or Fe K(beta) XES), seven Si(111) analyzers (in (444) order used for Cu 1s2p RIXS and RE EXAFS). All the analyzers have been commissioned to determine the exact focal length and energy resolution. During the commissioning phase, data of both models and biological systems have been successfully measured for all three methods. The instrument will be further refined during the coming year and work will continue with collaborative user groups, and theory for the analysis of data will be developed.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目和 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 基于用于共振非弹性 X 射线散射 (RIXS)、X 射线发射光谱 (XES) 和先进 EXAFS 的多个高分辨率晶体分析仪的光谱仪的开发和调试仍在继续。 目前，该装置有六台 Si(553) 分析仪（用于 Cu K(beta) XES）、三台 Ge(110)（按（440）顺序用于 Fe 1s2p RIXS）、三台 Ge（111）分析仪（按（333）顺序用于 Mn 1s2p RIXS 和范围扩展（RE）EXAFS，按（444）顺序用于 Zn K(beta) XES）、三台 Ge(310) 分析仪（按 (620) 顺序使用或 Fe K(beta) XES），七个 Si(111) 分析仪（按 (444) 顺序用于 Cu 1s2p RIXS 和 RE EXAFS）。所有分析仪均已委托确定准确的焦距和能量分辨率。 在调试阶段，所有三种方法的模型和生物系统的数据均已成功测量。 该工具将在来年进一步完善，并将继续与协作用户组合作，并开发数据分析理论。
