DIRECTOR’S CORNER

As we start a new year, it is worthwhile to reflect on the achievements of the last year and look forward to 2011. Last year was a milestone year for APS with outstanding machine performance, continued growth in the user community and scientific productivity, approval by DOE of Mission Need marking the initiation of the APS Upgrade Project, and the creation and review of many design reports along with the drafting of dozens of scientific case documents for the components of the Upgrade. I'd like to thank all the members of the APS community for their skill, creativity, and dedication in contributing to our combined and continued success.

In 2011 we can look forward to continuing to develop and apply the powerful capabilities of this unique facility and to plan for the future. We need to continue to address the most important scientific challenges of our nation and world, and to articulate how this research rewards the public for their investment in our work and facility during these difficult economic times. As the Conceptual Design for the Upgrade is created and reviewed, I'll be counting on the community to put forward our best ideas and participate in the peer review process.

We have an important meeting of the APS Scientific Advisory Committee to carry out a scientific review of the Upgrade scheduled for March 7. I especially want to thank the many users and staff who are contributing their time and effort to make the best possible scientific cases for the different potential components of the Upgrade and associated future plans. This shared activity is critical to future of APS and to worldwide progress in synchrotron research.

SCIENCE NEWS

1. Science Highlights

  • A Newly Discovered DNA Repair Mechanism
    Tucked within its double-helix structure, DNA contains the chemical blueprint that guides all the processes that take place within the cell and are essential for life. Therefore, repairing damage and maintaining the integrity of its DNA is one of the cell’s highest priorities. More…
  • An Electronic Dance of Spins and Orbits
    Because of their potential application in spintronic devices such as next-generation spin-based transistors, the quest for new materials with significant spin-orbit interactions in the electronic ground state is an area of intense research. Since the spin-orbit interaction increases rapidly with atomic number, materials containing heavy elements are natural candidates for this field of inquiry. More…
  • How a Virus Prepares to Infect Cells
    The atomic-scale arrangement of proteins in a structure that enables a virus to invade and fuse with host cells, showing precisely how the structure morphs with changing acidity to initiate infection, has been determined by investigators using the U.S. Department Energy’s Advanced Photon Source at Argonne. More…
  • Magnetic Switching under Pressure
    A material’s properties are a critical factor in the way that material can be used for practical applications. Magnetism is one such property, and magnetic switches are key components for advances in data storage and for displays in computers and cell phones. These properties are normally adjusted (or “tuned”) by changing the “recipe” during preparation. Now scientists at the U.S. Department of Energy’s Argonne National Laboratory, along with a collaborator from Eastern Washington University, have harnessed the power of extreme high pressure and discovered a novel approach to predictably tune the switching of a promising new family of next-generation magnetic materials.

3. Seeking Nominees for the APSUO Steering Committee—Deadline March 31
The APSUO Steering Committee is looking for potential nominees for this year's Steering Committee election. The Steering Committee meets four times per year. The APSUO advises the APS Associate Laboratory Director and acts as an advocacy group for the APS user community, provides advice to the ALD on matters affecting the user community, and assures good communication between the APS user community and the APS management.

Individuals interested in pursuing possible nomination should contact the Nominating Committee (Eric Dufresne, Alfonso Mondragon, and Alec Sandy) by March 31, 2011, via e-mail at apsuo_elections@aps.anl.gov.

4. X-ray App for I-Phone, I-Touch, I-Pad
Apple’s trademarked catch phrase “There’s an app for that!” has now entered the realm of synchrotron research! The “X-rayUtils” app (available for purchase on I-Tunes) is touted as being “perfect for synchrotron scientists and other x-ray users!” The developer has pulled together the kinds of information that could be useful at a beamline, including current storage ring status of synchrotron facilities around the world, lines (general atomic properties, absorption edges, and fluorescence lines with yields for hydrogen through californium), absorption calculations, and ion chamber calculations.

6. In Memoriam: Bob Batterman
Boris (Bob) Batterman, 80, passed away peacefully in his sleep on December 14, 2010. Bob was one of the founding fathers of synchrotron radiation research, the first director of the Cornell High Energy Synchrotron Source (CHESS), and one of the pioneers of dynamical diffraction theory and its application in materials science.

At the APS X-ray Centennial Symposium (October 1995), Batterman was one of seven distinguished scientists who shared their personal and professional insights into the course of x-ray research during the past century. He was also a guest speaker in April 1997 (during the Eighth Users Meeting for the APS) to commemorate the fiftieth anniversary of the discovery of synchrotron radiation. He also served on the APS’ Program Evaluation Board.

A memorial service is planned for the CHESS Users meeting on June 22, 2011. You can find his complete obituary from theithacajournal.com here.

BRIEFLY NOTED

-- 2011 American Association for the Advancement of Science Annual Meeting, February 17-21, 2011
The 2011 American Association for the Advancement of Science Annual Meeting (http://www.aaas.org/meetings/) is being held in Washington, D.C., February 17-21, 2011. Argonne National Laboratory is sponsoring an exhibitor's forum with Oak Ridge National Laboratory (ORNL) on "Integrated Resources: A Competitive Advantage of DOE National Laboratories," which will be held 3:30-4:30 pm on Friday, February 18, 2011, in room 158AB, Washington Convention Center. Argonne National Laboratory will be located in booth 325; ORNL is also participating in booth 420.

Abstract: User facilities at U.S. Department of Energy (DOE) national laboratories offer tremendous capabilities for multidisciplinary scientific research using x-ray, neutron, microscopy, and nanoscale techniques. The specialized instrumentation and expertise available at these facilities enable scientists from academia, industry, and other organizations to conduct experiments with resources typically not available at their home institutions. Additionally, the co-location of many of these facilities offers opportunities for the use of multiple techniques or probes on a single sample or group of samples. The goal of this workshop is to describe and promote the competitive advantages of conducting scientific research at these DOE user facilities. Workshop presenters: Brian Toby, Argonne National Laboratory, Malcolm Guthrie, Carnegie Institution of Washington, and Joseph Ng, University of Alabama-Huntsville.

The 11th Joint Accelerator School, which will be held at the Majorana Center for Scientific Cultural in Erice, Sicily, is retuning April 6-15, 2011, after a several year hiatus. Topics include instruments for photon science, synchrotron light sources, and free electron lasers. The session will focus on the physics insights and technological innovations in accelerators, x-ray beamlines and experimental techniques that are making possible a new generation of light sources to meet the increasing performance demands of user scientists.

This course will be of interest to physicists and engineers designing light sources, to operators of synchrotrons and FELs, as well as to beamline scientists and users of synchrotron light sources and free electron lasers. The lectures will include machine physics and technology plus scientific application and experimental techniques.
