The SSRL Organization Executive Committee presented the 2008 Farrel W. Lytle Award to Robert A. Scott in recognition of his contributions to synchrotron radiation research. For the past three decades, Scott has been a leader in the use of x-ray absorption spectroscopy to study the structures of metal-containing sites inside proteins. These centers carry out the biological work of the protein. More recently, he has developed new techniques to expand the capabilities of XAS. Besides his scientific contributions, Scott has also shared his expertise in using XAS to study biological systems with many young scientists through the years. "Bob's lectures on XAS served as a model that many of us have used for our own presentations at summer schools, such as the one that SSRL now offers," said James Penner-Hahn, professor of chemistry and biophysics at the University of Michigan.
The William E. Spicer Young Investigator Award was presented to R. Joseph Kline, a staff scientist at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. The award, honoring one of the founders of SSRL, recognizes a young investigator who has made important technical or scientific contributions that benefit the light source community. Kline was recognized for his seminal studies on the effect of molecular weight on the performance of polymer semiconductor field effect transistors and his expertise in grazing incidence x-ray diffraction (GIXD), atomic force microscopy, and organic thin films. According to University of California at Santa Barbara collaborator Michael Chabinyc, "Joe's previous work continues to generate interest. He has four publications that have been cited more than 50 times with increasing numbers of citations each year".
Ajay Virkar, a graduate student in the Department of Chemical Engineering at Stanford University, received the Melvin P. Klein Professional Development Award. The Klein Award, which includes a certificate and $1,000, recognizes a student for outstanding research using SSRL facilities. Using grazing incidence x-ray diffraction (GIXD), Virkar was able to study the sensitivity of organic thin film growth and crystallinity to very small changes in the nature of the surface on which they are deposited. These findings have made significant contributions to optimizing organic thin films for next generation flexible electronics. Virkar also demonstrated how sample preparation and experimental setup effects can often dominate the obtained results, findings that will greatly benefit the field of thin film material science. "I think the success of this project in such a short time had a lot to do with Ajay's persistence, patience, careful observation, intelligence and genuine interest in finding answers to scientific problems," said Zhenan Bao, Associate Professor of Chemical Engineering at Stanford.
Approximately 315 individuals participated in the various activities of the second joint LCLS/SSRL Users' Meeting held October 15-18, 2008. The four-day event began on Wednesday with an LCLS-themed science and development session held concurrently with two SSRL-related workshops: Advanced Topics in EXAFS Analysis and Applications; Crystallography Made Easy through Automation. Thursday was devoted to a joint LCLS/SSRL session including LCLS and SSRL overview talks, updates from Washington, science highlights, and a keynote speech by SLAC director Persis Drell on the future of photon sciences at SLAC (see SLAC Today). The full-day plenary session ended with the user scientific poster session, reception and dinner. Activities resumed on Friday with an SSRL session devoted to science and technical developments as well as two concurrent LCLS workshops: Application of Coherent X-rays at the LCLS; Atomic, Molecular & Optical Physics with the LCLS. The final event on Saturday, October 18 was an all-day joint SSRL/LCLS/ALS workshop on Soft X-ray Beam Line for Material and Energy Science at the LCLS.
The LCLS Users' Organization met on October 15th to introduce the members of the LCLS Users' Executive Committee (LCLS UOEC) and to discuss issues important to the user community as LCLS plans to begin its first user operations later in 2009. The draft LCLS UOEC charter is posted for interested to users to review.
The SSRL Users' Organization met on October 17 to announce election results, to obtain feedback from the last meeting, to begin to plan the next users' conference, and to discuss issues important to users, including a plan to improve the process of ordering and charging users for Liquid Helium at the beam lines.
