GISAXS = Grazing-Incidence Small-Angle X-ray Scattering



Grazing Incidence X-ray  Scattering  in the small angles is a technique which allows to obtain informations in the range of size going from 1 to 1000 nm.

The technique of central scattering of the X-rays in grazing incidence (GISAXS) was developed at first on synchrotron to characterize the density correlations in the nanometric scale and/or the shape of nanoscopic objects at surfaces or in thin films

GISAS combines the accessible length scales of Small-Angle Scattering (SAS) [the mesoscopic length scales, incident beam definition by multiple slits, area detector] and the surface sensitivity of Grazing Incidence Diffraction (GID) [the scattering geometry and sample goniometer].
