GSECARS
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:

GSECARS Comprehensive Overview

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
Microtomography

Future of COMPRES, GSECARS, and Synchrotron-Based Earth Science Research

Recently, NSF released a proposal solicitation for a new organization for management of synchrotron-based analytical capabilities for Earth and Environmental Sciences research and training. GSECARS is working with the larger Geoscience community to create a new and innovative organization in response to this call. More information about this effort can be found here.
