The 9th canSAS (Collective Action for Nomadic Small Angle Scatterers) workshop will take place at the Lawrence Berkley National Laboratory and SLAC National Accelerator Laboratory, San Francisco, CA, USA from June 5-7, 2017.

CanSAS is an ongoing activity to provide the small-angle scattering user community with shared tools and information.

This work involves both users and facilities and currently includes:

  • Providing access to information about small angle scattering
  • Providing information about SAS facilities
  • Providing forum for discussions regarding reliability of data, analysis, uncertainty estimates, and interpretation
  • Working with reference samples to allow comparison of instruments and better understand reliability issues
  • Proposing and agreeing common reduced data formats

Jeff Penfold awarded the 2013 Rideal LectureshipJeff Penfold

The Society of Chemical Industry and the Royal Society of Chemistry have jointly awarded their 2013 Rideal Lectureship to Professor Jeff Penfold of the STFC ISIS Pulsed Neutron & Muon Source and Oxford University. The Rideal Lectureship commemerates the great English physical chemist, Sir Eric Rideal FRS, whose work had such impact on the fields of electrochemistry, chemical kinetics, catalysis, electrophoresis, colloids and surface chemistry.

Jeff’s work has been highlighted because of his major scientific contributions to surfactant, colloid and interface science. He and John Hayter were the first people to formulate a strategy and the necessary analytical methods for the quantitative interpretation of neutron small angle scattering data from micellar solutions (indeed these methods are still the main ones used today). Second, with colleagues at Unilever plc, Jeff has pioneered the development of shear-flow methods in conjunction with small angle scattering. And thirdly, Jeff has played a major role in both the instrumental and methodological development of neutron reflectometry, now widely used for studying interfaces of all kinds.

Calling all Biological Solution Small-Angle ScatterersPDB-SAS Task Force Logo

During the SAS2012 meeting in Sydney, a well-attended panel discussion was held to discuss two related matters:

(1) publication guidelines for solution studies of biological macromolecules that use small-angle scattering to propose a 3D molecular model, either atomistic or a shape model, and

(2) the work of the Protein Data Bank Small-Angle Scattering Task Force (PDB-SAStf) that has been charged with considering whether solution scattering-based bio-molecular models should be archived.

At the panel discussion, it was agreed that a web page would be established to enable submissions from the community on these issues for consideration in the further development and communication of the guidelines.

The PDB-SAStf home page ( now includes a link (SAS2012 Report) to a summary of the panel discussion, including the presentations made, as well as a link to what will become the discussion archive (Discussion List Archive) and where instructions on how to make a submission may be found.

Interested members of the small-angle scattering community are encouraged to review the current state of the draft guidelines and to contribute comments.

As the community of structural biologists using small-angle solution scattering continues to expand, community engagement in guiding publication practices will ensure that results can be evaluated by reviewers and readers alike and promote confidence in the valuable contributions these studies can make.

Otto Glatter awarded the 2012 Guinier PrizeThe 2012 Guinier Prize for Lifetime Achievement in Small-Angle Scattering is awarded to Professor Otto Glatter of the University of Graz, Austria

The 2012 Guinier Prize for Lifetime Achievement in Small-Angle Scattering is awarded to Professor Otto Glatter of the University of Graz, Austria: for his dedicated development, application, propagation and dissemination of small-angle X-ray, light and neutron scattering methods over more than 40 years; for his pioneering work on the development of the indirect Fourier Transform method and its application to solve practical problems in real materials across many fields, especially in polymer science, soft matter and nanoparticle systems, and its extension to concentrated systems; and for his universally recognized service in building up the international small-angle scattering community through teaching and training, software development and publication, development of instrumentation, and the writing of a widely used teaching text.

The canSAS VIIIworkshop will be held in Tokai Japan at JPARC April 14-16 .  The aim of this workshop is to provide a forum for sas users and providers to come together to discuss common needs and issues, to learn from each others experiences, discuss current best practices, hear about emerging techniques, and when possible to identify areas where the field/state of the art could be improved by bringing together the people that are interested and able to work cooperatively to solve the problem. Since  the goal of the workshop is to foster discussion and collaborations on issues affecting the global sas community (nomadic scatterers) besides participating in the discussion sessions, please consider submitting a poster.  Posters are excellent ways to provide basic information that can then be used to seed or enhance discussions. 



The 16th International Conference on Small-Angle Scattering will be held in Berlin, 13 - 18 September, 2015. For more information see the conference website.

New Versions of FibreFix

FibreFix is a well-established software package for the processing of fibre diffraction (and similarly oriented) data. It provides a platform integrating several programs. Two new versions of the package have just been released, one for Windows 7 and higher operating systems (fixing a legacy issue with Microsoft .NET Framework 1 in the original XP version), and another coded in Java (which it is hoped will facilitate future integration into ImageJ).

To download the new versions, please visit the Software page.

Australian Synchrotron answers century old scientific question

Researchers at Monash University have used x-ray beams created by the Australian Synchrotron (AS) to discover how enzymes work to dissolve blood clots and clean up damaged tissue in the body - a finding that could ultimately lead to a reduction in the number of heart disease-related deaths occurring each year as a result of blood clots.
