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.***
