More information on SAXS 


Two Small-Angle X-ray Scattering (SAXS) instruments have been installed in the guide hall at OPAL. The SAXS instruments are equipped with Cu Kα sources and pinhole collimation. SAXS is complimentary to Small Angle Neutron Scattering (SANS) which is available on the new QUOKKA instrument at the OPAL reactor. A variety of sample environments are available for solids and liquids, including temperature control units, GISAXS attachments, and flow through capillary designs. The instruments are capable of being run in various separate configurations which can be optimised for individual experiments.



SAXS is used to study any materials with structure of the length scale 1-100nm. The performance of many advanced materials is crucially dependent on nanostructure, and SAXS can be used to study this. It can be used for study of density variations, colloidal sizes, particles sizes, porosity, domain sizes, orientation, phase identification, the list is endless. With research being directed more towards nano-sized science, SAXS is becoming a widely used tool.
