SSRL to Host Annual Users’ Meeting and Workshops October 15-19

By Cathy Knotts

Plans are underway for the 32nd Annual SSRL Users’ Meeting on October 17-18, (SSRL32), co-chaired by Clyde Smith (SSRL) and Joy Andrews (CSUEB). User research results and new developments at SSRL will be shared through invited talks and poster presentations. This meeting will feature sessions on x-ray absorption spectroscopy, structural genomics, ultrafast science and a sampling of materials research from other DOE labs.

There will also be a young investigators session, and the recipients of both the Lytle Award and the W. E. Spicer Young Investigator Award will be announced at this meeting. SSRL32 will provide a valuable opportunity for staff to interact with users from a broad range of scientific disciplines, vendors of accelerator products and services, and colleagues from other DOE facilities.

Several workshops will also be held in conjunction with this annual meeting.

Advances in X-Ray Scattering/Diffraction Studies on Non-Crystalline Biological Systems Workshop, Saturday and Sunday, October 15-16, chaired by H. Tsuruta.

The significance of non-crystalline diffraction techniques has been rediscovered in recent years by an increasing number of structural biologists to complement higher resolution structures by crystallography, NMR and cryo-EM. The latest advances in X-ray solution scattering, fiber and membrane diffraction studies on biological systems will be reported by several experts in a diverse spectrum of structural biology benefiting from non-crystalline diffraction studies. A mini tutorial session on the advanced computational techniques for solution x-ray scattering is planned. The participants will also receive updates on current and future developments at SSRL beam line (BL4-2), a dedicated small angle scattering/diffraction facility for structural biology.

Soft X-Ray Science at LCLS, Tuesday and Wednesday, October 18 - 19, chaired by Jan Lüning, Anders Nilsson and Jo Stöhr.

This workshop is aimed at the formation of a user community with a common interest in ultrafast and ultrabright soft x-ray pulses from a free electron laser like LCLS. The workshop will bring together scientists interested in developing new techniques and tools tailored for experiments relying on ultrafast soft x-ray laser pulses with scientists interested in utilizing the unique properties of such soft x-ray pulses for their research. The workshop will start with a series of invited talks that will give an overview about soft x-ray laser sources and techniques currently available or under development as well as about first performed and currently planned or envisioned experiments utilizing soft x-ray laser pulses. In order to provide an environment for intense discussion, all participants are encouraged to contribute to this workshop. Please send a title of your presentation to Jan Lüning ( In addition to contributed talks there will also be time reserved for ‘walk-in’ presentations.

The Role of Small Angle X-Ray Scattering in Materials Science, Wednesday, October 19, chaired by Mike Toney and John Pople.

This will be a hands-on workshop to demonstrate the burgeoning applicability of small-angle x-ray scattering (SAXS) resulting from the expansion of research and development on the nanoscale. The day will begin with presentations, briefly showing the techniques involved in SAXS in Materials Science and more closely focusing on current experimental data at the forefront of research which demonstrate the power of SAXS capabilities. The presentations will be semi-formal, with questions and discussion encouraged. Attendees will then move onto the SSRL beam line floor to gain hands-on control of configuring the SAXS beam lines (BL1-4 and BL4-2) and collecting and analyzing data. New software recently developed for data analysis will be demonstrated. This practical aspect of the workshop will highlight both the techniques involved in SAXS data collection, reduction and analysis as well as identifying the limitations of existing beam line facilities. A final presentation will outline suggestions for a new Materials Science beam line at SSRL which can overcome those limitations and advance the capabilities that SSRL can provide to the Materials Science community.
