USAXS vs. SAXS vs.WAXS

Ultra-small and Small Angle X-ray Scattering -USAXS and SAXS- and Wide Angle X-ray Scattering -WAXS- are available at ChemMatCARS. The major difference in these techniques is related to the mechanism producing the scattering. USAXS and SAXS arise from inhomogeneous electron density on different length scales ranging from angstroms to microns. WAXS arises more specifically from regular, periodic variations of electron density over length scales that are large compared to the repeat distance.
