Polychromatic SAXS
The Color X-Ray Camera (CXC) enables energy dependent analysis of diffraction rings gained with polychromatic SAXS, resulting in faster measurements with more data and higher angular resolution.
Most Small Angle X-ray Scattering (SAXS) systems require an X-ray source that is monochromatic. Since monochromation is inherently inefficient, these systems require expensive monochromators and high flux X-ray systems. In contrast, with the CXC, no monochromation is required. The resulting X-ray data can be energy filtered or processed to create diffraction patterns or reciprocal space images. As shown in the SAXS images from a sample of silver behenate (AgC22H43O2), monochromatic SAXS will result in the typical ring pattern (right image). Although the rings are larger in the polychromatic case (left image), the CXC enables energy dependent analysis of the diffraction rings, resulting in a faster measurement with more data and high angular resolution.
