The Soft Matter Interfaces (SMI) beamline at NSLS-II is a synchrotron undulator-based instrument focused on structural measurements of surfaces and interfaces. The instrument is optimized for x-ray scattering in grazing-incidence mode; i.e. grazing-incidence small-angle x-ray scattering (GISAXS) and grazing-incidence wide-angle x-ray scattering (GIWAXS/[[GIXD]). SMI can also perform transmission-mode scattering measurements (SAXS/WAXS).
