9906456Rivers This award provides partial funding support for the operation and maintenance of the GeoSoilEnviroCARS (GSECARS; CARS = Consortium for Advanced Radiation Sources). GSECARS is located at the Advanced Photon Source (APS) in Argonne National Laboratory. The APS is a synchrotron electron/positron storage ring used to generate brilliant X-radiation for materials research. GSECARS operates two X-ray beamlines used primarily for applications in the earth sciences. The research conducted at GSECARS makes use of the capabilities of brilliant, highly collimated, X-ray beams to advance knowledge of the composition, structure, and properties of earth materials. Specific techniques employed by GSECARS users include: (1) high-pressure/temperature crystallography of samples in a diamond anvil cell or in a multi-anvil large volume press; (2) powder, single crystal, and interface diffraction techniques; (3) X-ray absorption fine structure analysis (XAFS); (4) X-ray fluorescence microprobe analysis, and; (5) X-ray computer assisted microtomography.***

该合同为GeoSoilEnviroCARS （GSECARS; CARS =先进辐射源联盟）的运行和维护提供部分资金支持。GSECARS位于阿贡国家实验室的先进光子源（APS）。APS是一种同步电子/正电子存储环，用于产生辉煌的x射线，用于材料研究。GSECARS操作两条主要用于地球科学应用的x射线束线。在GSECARS进行的研究利用了明亮的、高度准直的x射线光束的能力来推进对地球材料的组成、结构和性质的认识。GSECARS用户采用的具体技术包括：(1)在金刚石顶砧室或多顶砧大容量压力机中对样品进行高压/温度结晶学；(2)粉末、单晶和界面衍射技术；(3) x射线吸收精细结构分析（XAFS）；(4) x射线荧光显微探针分析；(5) x射线计算机辅助显微断层扫描
