GeoCARS A National Resource for Earth, Planetary, Soil and Environmental Science Research at the Advanced Photon Source

该合同为位于Argonne国家实验室的先进光子源（APS）的几个实验站的设计、建造、设备和操作提供支持，这些实验站共同被称为一个部门。APS是一种正电子存储环或同步加速器，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，为需要了解物质原子和分子结构的研究提供了一种革命性的新工具。在高压下地球材料的矿物物理学、环境地球化学和土壤科学等研究领域处理地球材料特性的地球科学家将通过APS的GeoCARS部门获得APS的x射线辐射，该部门将作为整个地球、行星、土壤、APS的GeoCARS部门将包括高压研究设施，包括金刚石砧细胞和大容量压力机，衍射和散射，吸收光谱和异常散射，荧光微探针分析和微断层扫描。GeoCARS部门将由芝加哥大学的先进辐射源联盟运营和管理。＊＊＊

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. ***
