The SSRL Organization Executive Committee presented the 2009 Farrel W. Lytle Award to SSRL Senior Scientist Mike Toney. The prize works to foster collaboration between SSRL users and staff and recognizes an individual who has made significant technical or scientific contributions in synchrotron radiation-based science. Mike Toney received the award for his outstanding support of user science programs and innovation in the use of X-ray scattering in organic thin films and other energy-related materials. Although he was not able to attend in person, Farrel Lytle sent a letter congratulating Mike for his accomplishments and especially for his dedication to helping others achieve their scientific goals.
The William E. Spicer Young Investigator Award was presented to physicist Yulin Chen of the Stanford Institute for Materials and Energy Science (SIMES). The award, named for Stanford professor and SLAC researcher William Spicer (1929–2004), and his wife Diane, who passed away in 2009, is given to an early career researcher whose work is beneficial to the lightsource community. Yulin presented his work on experimental realization of a large gap 3D topological insulator with a single dirac-cone on the surface. "I am very glad that our work was acknowledged," Chen said of the award. "I feel very excited not only because of the prize itself, but also because we could demonstrate the great opportunity SSRL provides for science. I hope the lab will keep developing its remarkable capabilities for experiments and become an even better platform for more exciting science to be carried out."
Leslie Jimison received the 2009 Melvin P. Klein Scientific Development Award in recognition of her work on the development of diffraction-based characterization tools for the investigation of texture, mosaicity and crystallinity in polythiophene thin films at SSRL. The Klein Award recognizes outstanding research and comes with a $1,000 award to help recipients disseminate their scientific results. "The award is a kind recognition for my work at SSRL," Jimison said, adding that she will use the award funds to offset travel expenses. "It will allow me to attend a conference not otherwise possible, where I will share my ideas, learn new ideas from others and meet other people in my field."
Approximately 275 individuals participated in the various activities of the third joint SSRL/LCLS Users' Meeting held October 18-22, 2009. The five-day event began on Sunday, October 18th with a special symposium celebrating 35 years of outstanding science at SSRL, including honoring its founding Director Sebastian Doniach on the occasion of his 75th birthday. Thirty-five years ago, the Stanford Synchrotron Radiation Project (SSRP) began operations. SSRP was the precursor to today's SPEAR3 ring and the Stanford Synchrotron Radiation Laboratory (renamed in 2008 to Stanford Synchrotron Radiation Lightsource). SSRL science launched with five experimental stations sharing SLAC's first x-ray beam line. The SSRP was the world's first synchrotron radiation hard x-ray lightsource based on an electron storage ring. In addition to reviewing technical accomplishments and research highlights, future scientific and technical opportunities were discussed at this special symposium.
SSRL/LCLS 2009 officially began on October 19 with a joint plenary session that features updates from SLAC and DOE, a preview of the workshops, a user science poster session, and a keynote presentation by Bill St. Arnaud on green IT developments. The Spicer Young Investigator Award, Klein Professional Development Award, Lytle Award, and the Outstanding Student Poster Session Awards mentioned above were presented on this day.
Sessions focusing on SSRL and LCLS facility, instrumentation, and user science were held concurrently on October 20, followed by meetings of the SSRL and LCLS Users' Organizations. LCLS talks, introduced by Session Chair Jochen Schneider included an LCLS LUSI instrument overview by John Arthur and instrument updates from Michal Rowen (SXR), David Fritz (XPP), Sebastien Boutet (CXI), Aymeric Robert (XCS), and Hae Ja Lee (MEC). Paul Emma presented the latest machine developments including LCLS operations at the soft x-ray energies. Ryan Coffee spoke about laser systems. John Bozek reported on the status of the AMO instrument, and several users shared their experiences with user-assisted commissioning experiments, including Elliot Kanter (observation of x-ray multiphoton processes), Cosmin Blaga (above threshold ionization), and Nora Berrah (double core hole and non-linear x-ray processes in molecules).
Following the LCLS session on October 20th, the LCLS Users' Organization met to introduce the members of the LCLS Users' Executive Committee (LCLSUEC). LCLSUEC Chair Dick Lee moderated the meeting to approve the revised charter and to discuss issues important to the user community. LCLS Deputy Director Uwe Bergmann reviewed access and proposal review policies, operating parameters, and guidelines for collaborating teams in presenting results based on experiments conducted at LCLS.
Apurva Mehta chaired the first part of the SSRL Facility, Instrumentation and Science Highlights Session which focused on new techniques and capabilities including Aaron Lindenberg's talk on ultrafast science/pump probe experiments at SSRL; Joy Andrews Hayter's talk on transmission x-ray microscope imaging at SSRL; and Uwe Bergmann's talk on the new advanced x-ray spectroscopy station at the SSRL beam line 6-2. Katherine Kantardjieff chaired the next session focusing on Structural Molecular Biology. Talks included visualizing functional conformational change--a combined crystallography, SAXS and computational approach (Edward Snell, HWI); structural analysis of the mammalian ABC transporter P-glycoprotein (Andrew Ward, TSRI); techniques and tactics used in determining the structure of the trimeric ebolavirus glycoprotein (Erica Saphire, TSRI); lessons learned from structural studies of nitric oxide synthase--new tools to design selective enzyme inhibitors (Elsa Garcin, UMBC), and electronic structure differences in solution and crystalline oxyhemoglogin (Ritimukta Sarangi). The Environmental and Materials Session was chaired by Donghui Lu and included talks on lensless nanoscale imaging--combining MAD crystallography with x-ray holography (Andreas Scherz); precise structure of pentacene monolayers on amorphous silicon oxide and relation to charge transport (Stefan Mannsfeld); ions in the clutches of carbon nanotubes (Jason Holt, LLNL); and a new type of molecular self-ordering in organic solar cell materials (Roman Gysel, Stanford University).
Following the SSRL session on October 20, the SSRL Users' Organization met to announce election results, to review the latest features of the user portal for requesting beam time and user support, and to obtain feedback from the last meeting to assist in planning the next users' conference.
On October 21-22, several concurrent workshops were held:
- SSRL Imaging Group Workshop
- Macromolecular Crystallization, Sample Preparation and Synchrotron Data Collection
- LCLS Beam Line for Soft X-Ray Science
- X-ray Pump Probe Instrument at LCLS - Experiment Preparation Workshop
This annual event is a valuable opportunity to learn about the latest plans, new developments and exciting user research at LCLS and SSRL. It is also a great time to interact with other scientists, potential colleagues, and vendors of light source related products and services. We look forward to seeing you again next year -- mark your calendar for October 18-21, 2010!
