Welcome to I22

Post-Doctoral Research Associate - Ultra-Small Angle X-ray Scattering

We now have an opportunity for a highly motivated scientist, at Post-Doctoral Research Associate level, to assist in the commissioning and scientific exploitation of the new instrument. You will focus on the development of fast scanning technologies to allow for the most efficient use of instrument time. There will be opportunities to develop your own research program in the area of ultra-small angle X-ray scattering both independently, and in collaboration with the Diamond I22 Beamline user community. See Diamond Vacancies for more details

I22: Multipurpose SAXS/WAXS

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 hundred nanometres with high resolution. At 12.4keV, for example, the SAXS q-range is 0.0187-9.8 nm-1 dependent on camera length. For WAXS 0.72 to 47nm-1

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

Beamline Paper

We have 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.
