I am currently the main instrument scientist of the world-wide best instrument for small-angle scattering, APS USAXS/SAXS/WAXS instrument, located at beamline 9ID. Me and my colleagues work with scientists from all fields on application of small-angle scattering techniques for their specific problems. From metals, polymers, ceramics to food products, high explosives, nuclear materials,… we do it all. Ultra-Small-Angle, Small-Angle, and Wide-Angle (aka: powder diffraction) scattering are uniquelly applicable techniques and we do it all.
I am also author of small-angle scattering analysis package Irena as well as software package for area detector data reduction Nika. For more details see the linked site as well as YouTube channel with instructions and explanations.
In summary, at our USAXS/SAXS/WAXS instrument we provide unique ​“one stop shop” - we have instrument with of the largest scattering vector and intensity ranges in the world, supported by experience of 20+ years and software tools for data analysis, suitable for most materials science.
