9317772 Rivers This award provides support for the design, construction, equipping and operation of several experimental stations, jointly referred to as a sector, at the Advanced Photon Source (APS) located at the Argonne National Laboratory. The APS, a positron storage ring or synchrotron capable of producing hard x-radiation of much greater flux, brilliance, intensity and photon energy than previous x-ray sources, provides a revolutionary new tool for research requiring an understanding of the atomic and molecular structure of matter. Earth scientists dealing with the characterization of earth materials in research areas including mineral physics of Earth materials at very high pressure, environmental geochemistry, and soils science will gain access to APS x-radiation through the GeoCARS sector at APS, which will be operated as a national user facility for the entire earth, planetary, soil, and environmental research communities in the U.S. The GeoCARS sector at APS will include facilities for high-pressure research with diamond anvil cells and large-volume presses, diffraction and scattering, absorption spectroscopy and anomalous scattering, and fluorescence microprobe analysis and microtomography. The GeoCARS sector will be operated and managed by the Consortium for Advanced Radiation Sources at the University of Chicago. ***

小行星9317772 该奖项为位于阿贡国家实验室的高级光子源（APS）的几个实验站（统称为一个部门）的设计、建造、装备和操作提供支持。APS是一种正电子储存环或同步加速器，能够产生比以前的X射线源更大的通量，亮度，强度和光子能量的硬X射线辐射，为需要了解物质的原子和分子结构的研究提供了革命性的新工具。地球科学家在研究领域处理地球材料的特性，包括地球材料在非常高的压力下的矿物物理学，环境地球化学和土壤科学，将通过APS的GeoCARS部门获得APS x辐射，该部门将作为整个地球，行星，土壤，APS的GeoCARS部门将包括使用金刚石砧室和大容量压力机进行高压研究的设施，衍射和散射，吸收光谱和异常散射，以及荧光微探针分析和显微断层扫描。GeoCARS部门将由芝加哥大学先进辐射源联盟运营和管理。 ***
