Welcome to I22

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
