Welcome to I22

Current Status of I22 for potential AP28 Experiments

In light of the current COVID restrictions we would ask ALL Users planning to apply for time on I22 in AP28 to get in touch with a member of the beamline staff 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.

I22: Small Angle Scattering & Diffraction

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

Biomechanics Facility at I22

Cardiff University have recently been awarded an MRC Grant to investigate soft tissue biomechanics. In collaboration with Olga Shebanova from I22, they plan to build a general purpose micromechanical tester for the User Community through Network involvement. See more in Beamline Upgrades Section

Offline SAXS - In Commissioning!

Diamond now hosts a new Offline SAXS User facility. Jointly bid for by Diamond and Leeds University the facility, funded by the EPSRC, will offer complimentary materials science measurements to those available on I22. A contract was placed with Xenocs to bring one of their first Xeuss 3.0 Q-Zoom instruments to Diamond in Spring 2019. This is now reaching the end of it's commisisoning phase.

The facility is located in a new purpose built laboratory and include Sample Environment Development facilities.

The SAXS equipment will in part be available via PRP for measurements and run by a dedicated technician supported by the Diamond SAXS team. Look for DL-SAXS in UAS!
