Acquisition of Advanced X-ray Detectors for Geoscience Research at the Advanced Photon Source

9413706 Rivers该合同为阿贡国家实验室高级光子源的五个实验站设计、购买和安装X射线探测器系统所需的部分资金，该实验站由GeoCARS部门组成。芝加哥大学先进辐射源联盟(CARS)致力于提供完成X射线探测器系统所需的剩余资金。GeoCARS是CARS的一个组织分支单位，致力于在APS建造和运营一个多用户设施，以满足地球科学研究界在使用同步辐射方面的需求。APS将于1995年在阿贡投入使用，它将提供比美国现有最亮的同步加速器源高1000倍的硬X射线，地球科学研究界将通过利用位于APS的GeoCARS部门的实验站获得这一强大的工具来表征地球材料的结构和成分。现有的极高X射线亮度将使X射线衍射和散射、X射线吸收光谱分析、X射线微探针和显微断层成像研究达到前所未有的空间和能量分辨率，应用于超高压、环境地球化学、土壤科学和农学以及废物处理等地球科学研究。该项目的目标是在APS的GeoCARS部门安装X射线探测器，以充分利用这一非凡而强大的新X射线源的空间、能量和时间分辨率特性。***

9413706 Rivers This award provides partial funding required to design, purchase the components of, and install X-ray detector systems for a group of five experimental stations comprising the GeoCARS sector at the Advanced Photon Source (APS) of Argonne National Laboratory. The University of Chicago's Consortium for Advance Radiation Sources (CARS) is committed to providing the remaining funds needed to complete the X- ray detector system. GeoCARS is an organizational sub-unit of CARS, dedicated to the construction and operation of a multi-user facility at APS designed to meet the needs of the earth science research community in using synchrotron radiation. The APS, to be commissioned at Argonne in 1995, will provide hard X-rays with 1000 times higher brilliance than the brightest existing synchrotron source in the U.S., and the earth science research community will gain access to this powerful tool for characterizing the structure and composition of earth materials by making use of the GeoCARS sector's experimental stations at APS. The extremely high X- ray brilliance available will permit unprecedented levels of spatial and energy resolution in X-ray diffraction and scattering, X-ray absoption spectroscopy, and X-ray microprobe and microtomography studies applied to earth science research in ultra-high pressure, environmental geochemistry, soils science and agronomy, and waste disposal. The goal of this project is to instrument the GeoCARS sector at APS with X-ray detectors that will take full advantage of the spatial, energy, and time resolution characteristics of this remarkable and powerful new X-ray source. ***
