BL11-NCD
Non Crystalline Diffraction beamline
Introduction
Small Angle X-ray Scattering (SAXS) experiments provides structural and dynamics information of large molecular assemblies like polymers, colloids, proteins and fibres. A wide range of fields (medicine, biology, chemistry, physics, archaeological, environmental and conservation sciences and materials) is covered by this technique. SAXS is a very powerful technique to study the supramolecular organization in biological systems, the structure and function of muscle filaments, corneal transparency, biological membranes, polymer processing, self assembly of mesoscopic metal particles, colloids, inorganic aggregates, liquid crystals and devices.
Recording simultaneously SAXS and WAXS (Wide Angle X-ray Scattering) deliver length scale from few microns to few angstroms.

Status
The optical system was defined in May 2006. Reception and subsequent assembly of the beamline components will start summer 2008. Installation of is now completed and the beamline started to receive external users in July 2012.
