BL16B1 Small Angle X-ray Scattering (SAXS) Beamline
1.     Introduction 
       
The beamline (BL16B1) is primarily a combined small-angle and wide-angle scattering instrument. Small angle and wide angle X-ray scattering (SAXS and WAXS), when coupled with synchrotron radiation, offers research opportunities in studying the microstructure, kinetics, dynamics and rheology of complex and nanostructured materials (polymers, colloids, fluids, liquid crystals, etc) over a wide range of length (e.g., from Angstroms to microns) and time (e.g., from microseconds to hours) scales. For example, the changes in nano-, micro- and supra-molecular structures of biological and synthetic macromolecules, including ionomers, block copolymers, and dendrimers, in solution and in melts, as well as gels and colloidal systems; the kinetics of phase transition in semi-crystalline polymers, blends and nanocomposites.
