Small-angle X-ray scattering (SAXS) is used to study morphological details at the nanometer scale. It covers a wide range of samples — from protein solutions over precipitates in materials to hierarchical structures in biological material. Highly brilliant sources and fast detectors allow scanning SAXS and tomographic non-destructive insights into the material . To reveal statistically relevant data, SAXS depends on the signal-to-noise ratio to uncover precise sample morphology.
Wide angle X-ray scattering (WAXS) complements information content with crystalline data on the underlying probed volume. HPC detectors with count rates above 1e6 photons/s/pixel and a cosmic background of 0.1 counts/h/pixel achieve a dynamic range of above 1e11. These detectors are the best choices for all SAXS/WAXS instruments. For some of our detectors a vacuum option is available.
" For small angle X-ray scattering (SAXS) on proteins data recording, a good signal-to- noise ratio is a necessity. The practical noise-free recording of SAXS data with the PILATUS detectors permits reliable data analysis and more accurate shape model building, even in dilute protein solutions. This property of the detector, in combination with the high dynamic range and the large active area, makes the PILATUS the detector of choice for SAXS solution scattering."
