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.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 基于多个高分辨率晶体分析仪的光谱仪的开发和调试工作仍在继续，该光谱仪用于共振非弹性X射线散射、X射线发射光谱和先进EXAFS。 目前，该装置有六个Si（553）分析仪（用于Cu K（β）XES），三个Ge（110）（以（440）顺序用于Fe 1 s2 p RIXS），三个Ge（111）分析器（以（333）顺序用于Mn 1 s2 p RIXS和范围扩展（RE）EXAFS，以及以（444）顺序用于Zn K（β）XES），三个Ge（310）分析器（以（620）顺序用于Fe K（β）XES），七个Si（111）分析器（以（444）顺序用于Cu 1 s2 p RIXS和RE EXAFS）。所有的分析仪都已投入使用，以确定准确的焦距和能量分辨率。 在调试阶段，所有三种方法都成功地测量了模型和生物系统的数据。 该工具将在未来一年内进一步完善，并将继续与协作用户团体合作，并将发展数据分析理论。
