We have just published a Review of I22 Operations. It contains a description of beamline. As part of the requirement to include Diamond in your publication acknowledgements and references please include this paper for all work carried out on I22. We hope you find it useful.
I22: SAXS/WAXS beamline at Diamond Light Source - an overview of 10 years operation

In light of the current COVID restrictions we would ask ALL Users planning to apply for time on I22 to get in touch with a member of the beamline staff (or I22@diamond.ac.uk) to discuss feasibility before submitting any proposals. Whilst we will make every effort to accommodate all experiments, some, because of their challenging nature, might be difficult to facilitate currently.
The high brilliance of the insertion device source on I22 allows structural investigation of materials under extreme environments (for example fluid flow at high pressures and temperatures). I22 provides reliable access to millisecond time scales, essential to understanding kinetic processes such as early folding events in proteins or structural evolution in polymers and colloids.
Simultaneous recording of both small and wide angle X-ray scattering (SAXS and WAXS) techniques in combination allows users to probe length scales ranging from a few Angstroms to several microns with high resolution.
Key Advantages of I22:
High flux: essential for SAXS studies of oriented samples.
High resolution tuneable energy: Useful for a range of sample environments including Pressure Studes.
Minimum beam divergence: critical for Ultra Small Angle X-ray Scattering (USAXS)
Partial 2D WAXS capability
Microfocus capability available. This can now be scheduled more flexibly due the the recently completed BCO Upgrade.
Grazing Incidence SAXS (GiSAXS). This is scheduled in blocks during the AP's as a purpose built Sample platform is installed to carry out the technique. Full access to I22's camera length range is available in this mode
