indexGIXS – software for visualizing and interactive indexing of grazing-incidence scattering data

Grazing incidence small- and wide-angle scattering (GISAXS, GIWAXS) are widely applied for the study of organic thin films, be it for the characterization of nanostructured morphologies in block copolymers, nanocomposites, or nanoparticle assemblies, or the packing and orientation of small aromatic molecules and conjugated polymers. Organic thin films typically are uniaxial powders, with specific crystallographic planes oriented parallel to the substrate surface. The associated fiber texture scattering patterns are complicated by refraction corrections and multiple scattering. We present an interactive graphics tool to index such patterns.
