http://www.classe.cornell.edu/~dms79/gisaxs/tutorial/SAXS-Guide-Smilgies.pdf WebThis essay sketches the development of X-ray Absorption Fine Spectroscopy (XAFS) ever since the second half of 20th century. At that time, synchrotrons started competing with X-ray discharge tubes as the sources of the excitation able to show the pre- and near-edge structures (XANES) and extended oscillations (EXAFS) that characterize the X-ray …

Here we give a basic introduction that focuses on concepts rather than on the complete mathematical description. The goal is to make some peculiar scattering features of GISAXS more accessible.

WebAug 24, 2024 · Unwarping GISAXS data. Grazing-incidence small-angle X-ray scattering (GISAXS) is a powerful technique for measuring the nanostructure of coatings and thin films. However, GISAXS data are plagued by distortions that complicate data analysis. The detector image is a warped representation of reciprocal space because of refraction, and …

WebGISXAS data could be interpreted the same way as small angle x-ray scattering (SAXS) experiment. Instead of having transmission geometry as SAXS, GISAXS relied on reflection of x-ray from the samples, which enables the thin film characterization, as more sample volume could be probed. The typical experiment setup is shown in figure 1[4].
