Description

Small Angle X-ray Scattering (SAXS) experiments provide structural and dynamic 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) can be covered by this technique. Recording simultaneously SAXS and WAXS (Wide Angle X-ray Scattering) results in a length scale which ranges from a few microns to a few angstroms.  

The SAXS beamline of ALBA has gone through a major upgrade in 2017. Upgraded items in the SAXS WAXS ExpErimental Techniques (SWEET) involve a new monochromator system, a new photon counting detector (Pilatus 1M), a new sample table with an additional rotating stage, and a beam conditioning optics with µ-focus and GISAXS/GIWAXS options. The project had some issues and explanations on how they have been overcome will be presented.

The beamline has now reached an international standard and idea for performing better science will be discussed.
