The Complex Materials Scattering (CMS) beamline at NSLS-II is a synchrotron instrument focused on x-ray scattering. It is located at 11-BM (bending magnet port) on the NSLS-II floor, and features a three-pole wiggler source. It can perform SAXS and WAXS experiments, focusing on ambitious synchrotron experiments, including in-situ or operando studies of materials during synthesis, processing, or operation; and autonomous experiments including high-throughput explorations and 'intelligent' machine-guided exploration of parameter spaces.
