SixS (Surfaces interfaces x-ray Scattering) is a wide-energy range (5 -20 keV) beamline dedicated to structural studies of interfaces (gas-solid, solid-solid or solid-liquid), as well as nano-objects.

SixS (Surface Interface X-ray Scattering) is a beamline dedicated to the study of X-ray scattering from surfaces and interfaces of hard and soft matter in various environments in the 5-20 keV energy range. To be sensitive to the surface all the studies will be performed in grazing-incidence geometry. The beamline will be equipped with two experimental hutches, which will be dedicated to the study of surfaces, interfaces and nano-objets prepared:

  • in-situ under UHV (Ultra High Vacuum, i.e. 10-10 mbar) conditions. A diffractometer will allow to measure X-ray scattering from samples under UHV;
  • in various environments (catalysis chambers, soft matter, electrochemical cells). A diffractometer coupled with exchangeable chambers will be able to measure X-ray scattering from sample surfaces both in vertical or horizontal geometries.

Grazing Incidence X-ray Diffraction (GIXD), Grazing Incidence Small Angle X-ray Scattering (GISAXS), anomalous surface X-ray scattering, X-Ray Reflectivity (XRR), magnetic surface X-ray scattering and coherent scattering experiments will be performed on both the facilities.
