Advanced Crystallography
ChemMatCARS – Advanced Crystallography program is dedicated to small-molecule single crystal X-ray diffraction. The diffractometers are pre-aligned internally and can be moved into the beam when required. This flexibility allows us to take advantage of beam availability at short notice, a capability that has been used extensively in user experiments.
The Advanced Crystallography program uses a “rapid setup” crystallography option that allows us to rapidly switch operation to the single-crystal instrument.
Liquid Interface X-ray Scattering
Synchrotron X-ray surface scattering is the most powerful probe of molecular and mesoscale structure at liquid-vapor and liquid-liquid interfaces. The precise and flexible design of the liquid surface and interface reflectometer at ChemMatCARS (APS, 15-ID-C) and the high brilliance and wide X-ray energy range (5-70 keV) offered in this third generation insertion device beamline provide a world-leading capability for the study of liquid surfaces and buried liquid-liquid interfaces.
Liquid Interface X-ray Scattering is used to investigate dynamical and structural properties of surfaces and interfaces in a variety of liquid systems.

Anomalous Small and Wide Angle X-ray Scattering
The ASWAXS facility at ChemMatCARS focuses on element specific structural study of soft matter systems such as polyelectrolytes, colloids, polymers, macro-ions in solutions, and nanomaterials at the length scales from sub-nanometer to hundreds of nanometers. ChemMatCARS has developed a set of easy-to-use analysis tools that enable users to extract the quantitative spatial distribution of specific elements (with atomic number Z> 25) within their samples from ASWAXS measurements.
Anomalous Small and Wide Angle X-ray Scattering focuses on element specific structural study of soft-matter in nano-dimensions.
