By providing information on the structure of matter at scales varying between nanometer and micrometer, the beamline SWING will help answering the numerous questions related to soft condensed matter, conformation of macro-molecules in solution and composite materials in material sciences. This experimental set up will allow small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering measurements (WAXS) to be performed simultaneously in the 5-17 keV energy range, as well as grazing incidence small angle scattering (GISAXS). Anomalous scattering experiments will be facilitated. Emphasis will be put on the variety of samples that can be studied, solutions, gels, amorphous solids, crystallised solids and the corresponding diversity of sample environments.
