Small and Wide-angle X-ray Scattering
Overview
ChemMatCARS operates three experimental stations in the areas of advanced small-molecule crystallography, liquid surface and interface scattering, and ultra-small to wide-angle scattering at the Advanced Photon Source (APS), the premier undulator-based synchrotron source of high-brilliance high-energy x-rays in the U.S.A. The instrumentation at ChemMatCARS provides information that addresses a broad range of issues in chemistry and materials research.
Scientific Focus
The scientific focus of user activities at ChemMatCARS is the study of structure and dynamics over the range of length scales from atomic and molecular to mesoscopic. The experimental techniques available to the scientific community span a spatial resolution of sub-angstrom to micrometer and a time resolution from 50 ns to minutes. These include:
High Precision Crystallography to study charge (i.e., electron) densities, bonding, microcrystals, resonant diffraction, high-pressure (up to 10 GPa) single crystal diffraction, and transient state/photo-crystallography.
Scattering From Liquid Surfaces and Liquid-Liquid Interfaces to measure atomic, molecular, and mesoscopic ordering at interfaces using resonant and non-resonant reflectivity, grazing-incidence diffraction and small angle scattering, surface fluorescence, surface diffuse scattering, and fast techniques, such as grazing incidence diffraction in the 1D pinhole geometry.
Ultra-Small-Angle X-ray Scattering (USAXS) and small and wide-angle x-ray scattering (SAXS/WAXS) to probe ordering in bulk materials on angstrom to micrometer length scales.
ChemMatCARS is mainly supported by the
National Science Foundation
and
Department of Energy
under grant number NSF/CHE-0822838.

The Advanced Photon Source (APS)
ChemMatCARS is located in the Advanced Photon Source at Argonne National Lab. We occupy Sector 15 in Building 434D, which includes staff offices, user labs, and experimental facilities.
The Advanced Photon Source (APS) is one of the most technologically complex machines in the world. This premier national research facility provides the brightest x-ray beams in the Western Hemisphere to more than 5,000 scientists worldwide.
Argonne National Lab (ANL) is a multidisciplinary science and engineering research center, where “dream teams” of world-class researchers work alongside experts from industry, academia and other government laboratories to address vital national challenges in clean energy, environment, technology and national security.
