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).
CHX can perform a variety of experiments:
- Can perform experiments from 2.1 keV to 24 keV.
- Energy resolution (double crystal monochromator): 10−4
At sample position:
- Focusing available to ~2.5 µm (V) and 25 µm (H)
SMI has taken first light, and is currently undergoing technical commissioning. Access will be available through the NSLS-II proposal system. Interested users should contact beamline staff.
