SWAXSlab -LIONS
Dedicated to material studies by X-ray scattering, the SWAXS-Lab Saclay Laboratory brings together equipment from the Leon-Brillouin Laboratory (LLB-UMR CEA-CNRS) and NIMBE (UMR 3685 CEA-CNRS), which are both partners from the NanoSaclay Labex.
Four complementary experimental X-ray scattering set-ups, Small Angle X-ray Scattering (SAXS), WAXS (Wide Angle X-ray Scattering), and GISAXS (Grazing incidence-SAXS), are installed. One of them has recently been acquired by the LLB: the new Xeuss 2.0 equipment, manufactured by Xenocs in partnership with the SOLEIL synchrotron, is very versatile with different observation ranges and allows automatic measurements on several samples (up to thirty).
SWAXS-Lab Saclay was designed to study the structure of materials at the nanoscale and also their evolution (change in pressure and/or temperature/adsorption ...). It allows complete experiments to be carried out, independently.
Main technical features
- USAXS : Ultra-Small Angle X-ray Scattering (Bonse-Hart geometry)
- SAXS : Small Angle X-ray scattering
- WAXS : Wide angle X-ray scattering
- GISAXS : Grazing Incidence X-ray scattering
Sample preparation
The transmission of the sample has to be as close as possible to 0.3 either at 8 keV (USAXS, SAXS) or at 17 keV (WAXS).
Powders, capillaries and films can be studied.
