DIRECTOR’S CORNER

This has been a very busy month for the APS Upgrade project. Our Scientific Advisory Committee held a review of the proposed Upgrade components March 7 - 9, which resulted in endorsement of all 35 of the beamline proposals and their prioritization into three categories: Very Strongly Recommended, Strongly Recommended, and Recommended. This scientific prioritization will be extremely useful in planning for the Upgrade and associated long-term improvements to APS, and I thank the committee and all of the community members involved in preparing and presenting the proposals. This review was followed almost immediately by the Argonne Director's Review of APS-U March 14-16, which looked at the draft Conceptual Design Report and the project scope, cost, schedule, and management in preparation for our DOE review in May. We received a tremendous amount of good advice from this review as well, which will serve us well as the project proceeds.

As of this writing, the budget outlook for FY 2011 remains uncertain, even though we are almost half way through the fiscal year. While the FY 2011 budget proposed by the President is strongly supportive of the DOE Office of Science, Basic Energy Sciences, APS operations, and Upgrade activities, bills introduced in Congress to date have included larger or smaller cuts to the Office of Science. Because of this uncertainty, APS is currently operating assuming an austere budget that maintains the normal 5000 hours of operation and maintains project activities through the upcoming DOE review, but delays ongoing beamline and machine improvements and Upgrade activities beyond CD-1.

Congress is expected to act in the coming weeks to produce a spending bill for FY 2011, and begin discussions on the FY 2012 budget. During these difficult economic times, we need to continue to help policymakers and the public to understand the difficult choices by articulating the ways in which research at APS addresses the most important scientific challenges of our nation and world, and rewards the public for their investment in our work and facility.

1. Science Highlights

  • A Molecular Fossil
    In today's world of sophisticated organisms, proteins are the stars. They are the indispensible catalytic workhorses, carrying out the processes essential to life. But long, long ago ribonucleic acid (RNA) reigned supreme. Now researchers from Northwestern University and The University of Chicago, using the Life Sciences Collaborative Access Team x-ray research facility at the U.S. Department of Energy’s Advanced Photon Source, have produced an atomic picture that shows how two of these very old molecules interact with each other. It is a rare glimpse of the transition from an ancient, RNA-based world to our present, protein-catalyst dominated world. More…
  • Velcro for Nanoparticles
    DNA can do more than direct how bodies are made — it can also direct the composition of many kinds of materials, according to a new study from the U.S. Department of Energy’s Advanced Photon Source at Argonne. More…
  • DNA Repair Protein Caught in the Act of Molecular Theft
    With a major assist from the U.S. Department of Energy’s Advanced Photon Source at Argonne, scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, cancer, and diabetes. More…
  • Revealing the Secrets of Chemical Bath Deposition
    X-ray absorption near-edge structure (XANES) spectroscopy is well known as a versatile and powerful technique for examining the microstructure of everything from crystalline solids to amorphous materials, even liquids. Its extreme sensitivity also makes it an ideal tool for probing the kinetics of various chemical reactions in situ. Experimenters utilizing the U.S. Department of Energy Office of Science’s Advanced Photon Source at Argonne recently demonstrated a new wrinkle for XANES that has opened a window on a poorly understood technique for deposition of materials. These insights will encourage the development of better-controlled and more precise chemical synthesis techniques for semiconductor and other nanomaterial applications, and are valuable as a demonstration of the extension of XANES spectroscopy into other realms of experimentation.

2. Stern, Lytle, Sayers, and Rehr Win 2011 Arthur H. Compton Award
Congratulations to Ed Stern, Farrel Lytle, the late Dale Sayers, and John Rehr, winners of the 2011 Arthur H. Compton award. Nominated for their pioneering development of the theory and use of x-ray absorption fine structure spectroscopy (XAFS), these individuals and their early work transformed how x-ray researchers around the world study local structure around x-ray absorbing atoms in gases, liquids, and amorphous and crystalline solids. Classic papers by these pioneers have been sited thousands of times and have influenced countless researchers. The Compton Award presentation will be made on Monady, May 2 as part of the APS plenary session of the 2011 APS/CNM/EMC Users Meeting.
