Small Angle Scattering (SAXS)

Small Angle X-ray Scattering (SAXS) covers the major disciplines of Biology, Chemistry and Physics delivering structural and dynamic information in nanoscience, mesoscopic architectures, supramolecular structures and nucleation/growth of crystals. SAXS is also proving important in archaeological, environmental and conservation sciences,  indicating an ability to span a wide range of scientific disciplines.

Diamond has two beamlines dedicated to SAXS I22 and B21 but several others that carry out SAXS experiments from time to time, I12 (high energy SAXS, 50 - 150 KeV) and I07 (GiSAXS).

SAXS School and Science Meeting Announced

We are happy to inform all SAXS users that we plan to hold both a Science meeting and one of our regular SAXS tranining Schools in June this year. Registration is now Open for both!

Software Improvements

The latest release of dawn, 2.11 (November 2018), includes an extensive set of data reduction tools for SAXS data. A detailed descriptiopn of these tools can be found in the recent paper by Pauw et al.

Dawn, with these tools, can be downloaded from We have also spent some time updating the manual section of our confluence site to accompany the new release together with the new Autoprocessing functionality.

A paper concerning the processing perspective available in Dawn was also published recently and has been highlighted on the Diamond website.

iNext Access Available

With B21 moving into operational mode we are happy to receive iNext users to the facility. More information can be found on on the iNext website.

New to SAXS?

  • The Beginners Guide to SAXS provides useful information on what is possible, helpful hints and tips for experiments and some basic background on our beamlines, I22 and B21. The Beginners guide also includes a useful reference book list for Small Angle Scattering.
  • A nice introduction to the technique was been printed in the 2015 issue of our "Inside Diamond" Magazine. You can find it on pages 20-21 of the magazine.
