GeoSoilEnviroCARS
GSECARS is a national user facility for frontier research in the earth sciences using synchrotron radiation at the Advanced Photon Source, Argonne National Laboratory.
GSECARS provides earth scientists with access to the high-brilliance hard x-rays from this third-generation synchrotron light source. All principal synchrotron-based analytical techniques in demand by earth scientists are being brought to bear on earth science problems: high-pressure/high-temperature crystallography and spectroscopy using the diamond anvil cell; high-pressure/high-temperature crystallography and imaging using the large-volume press; powder, single crystal and interface diffraction; inelastic x-ray scattering; x-ray absorption fine structure spectroscopy; x-ray fluorescence microprobe analysis; and microtomography.
