DIRECTOR’S CORNER
In the most recent addition to the family of APS beamlines, the Dynamic Compression Sector (DCS) has formalized its ties with the APS in a Memorandum of Understanding (MOU) signed on September 6. The DCS, which will reside on Sector 35, brings an exciting new research capability to our user program. As noted in the report from the DCS User Workshop held here in January 2012, “…in situ, time-resolved measurements at microscopic length scales constitute the overarching science need for achieving a fundamental understanding of the mechanisms governing time-dependent condensed matter phenomena (structural transformations, inelastic deformation and fracture, and chemical reactions) under dynamic loading.” The DCS is funded by the Department of Energy’s National Nuclear Security Administration (NNSA) and is managed as a partnership between Washington State University (WSU) and the APS. Signing the MOU were Yogendra Gupta, Director of the Institute for Shock Physics at WSU; Daryll DeWald, Dean of the WSU College of Arts and Sciences; Argonne Director Eric Isaacs; and myself. Among the distinguished guests attending the ceremony were Chris Deeney, NNSA Assistant Deputy Administrator for Stockpile Stewardship; and Keith LeChien, NNSA Federal Program Manager in the Defense Science Division.

Our accelerator systems and the personnel who maintain and operate them continue to establish new levels of excellence in providing x-rays to our users. Over the most recent three user runs since October 2011, fiscal-year records were set for availability (99.4%) and mean time between faults (199 hours). The previous best fiscal-year records were 98.6% and 101 hours, respectively, in FY2005 and FY2010. The new FY2012 records involved having only 25 faults and 31 hours of unplanned downtime over the entire year, compared with previous bests of 49 faults and 71 hours. This unprecedented performance was made possible by the diligence and hard work of many APS personnel over several years to analyze the causes of every fault and systematically develop solutions to improve the reliability of all of the accelerator systems.

As a final note, I would like to mention the 2012 Argonne Energy Showcase that took place on Saturday, September 15. More than 12,500 members of the public came to Argonne for an informative day highlighting energy-related research. A team of 134 APS personnel guided visitors through a tour of the facility, answered a seemingly endless stream of questions about APS science and engineering, and delighted visitors (especially the kids) with 30 exhibits and demonstrations including 3-D tomography of new materials for lighter cars and airplanes, a nanometer-scale look into green energy materials using hard x-ray fluorescence microscopy, a “virtual linac,” a miniature beamline, robotics, acoustic levitation, and rapid prototyping of APS beamline components. A video of Chris Benmore demonstrating the magic of acoustic levitation has gone viral and is available at http://www.youtube.com/watch?v=669AcEBpdsY.

APS Upgrade News by George Srajer, APS Upgrade Director
Since the last edition of User News, the APS Upgrade has had two successful reviews. On August 16, the Project presented to DOE Lehman Committee a case for Long Lead Procurement (LLP) for Resonant Inelastic X-ray Scattering (RIXS) and Advanced Spectroscopy/LERIX (ASL) beamlines. The review was successful and the Office of Science Energy Systems Acquisition Advisory Board (ESAAB) subsequently reviewed and approved the initial LLP on August 30. This decision is equivalent for the Critical Decision CD-3A. For the RIXS beamline, the approval will enable procurement of front end components, undulators, vacuum chambers, and radiation enclosures starting immediately and continuing in fiscal year 2013. The Project has funds to proceed for all these items. For the ASL beamline, the approval scope includes radiation enclosures, monochromators, and mirrors. However, additional budget authority will be required in fiscal year 2013 to proceed with ASL. The CD-3A approval is an important step for the Project because the LLP will accelerate the project schedule and reduce schedule risk.

I am also pleased to report the successful completion of the Director¹s CD-2 Review of the APS Upgrade that took place between September 11 and 13. The Committee, chaired by Ed Temple, was charged by the ANL Director to assess the readiness of the Project in areas of management, scope, cost and schedule, environment, safety and health, quality assurance, and documentation preparation. The reviewers were uniformly positive in saying that we are on track for achieving a successful DOE Lehman CD-2 review in December. This outcome is central to one of Argonne¹s Performance Evaluation and Measurement Plan goals for fiscal year 2012.

During the course of the Director’s Review, 20 reviewers heard over 40 presentations spanning the scope of the Project. The Committee made thorough and constructive recommendations that will certainly help improve our preparedness for the CD-2 Review. 

Both of these reviews were important milestones for the APS Upgrade. I look forward to continue working with our user community to ensure future successes.

Rapid Acquisition Powder Diffraction Program Relocates to Beamline 17-BM
The APS X-ray Science Division is pleased to announce an enhancement to powder diffraction capabilities at the Advanced Photon Source. Effective from the 2012-3 cycle, the rapid acquisition (or ‘area detector’) powder diffraction program, formerly at beamline 1-BM, has relocated to beamline 17-BM.

The program will maintain a focus on in situ measurements with the new location providing improvements to several key components of the optics and experimental stations. All standard experimental capabilities previously offered at 1-BM will remain available for on-site users including high-throughput sample changers, variable temperature options (100–1200K), and a compact flow cell apparatus for controlled atmospheres. The program will continue to utilize a Perkin-Elmer amorphous silicon flat panel area detector, allowing the continuous collection of moderate resolution powder diffraction data with time resolutions from fractions of seconds (Δd/d: ~1x10 -3; typical data collection times: 0.1–30 seconds). The initial beamline energy range available at 17-BM will be 8–18 keV.

These capabilities complement those of beamline 11-BM, which is dedicated to high-resolution powder diffraction measurements. Beamline 11-BM operates over the energy range 15–35 keV, and uses multiple Si crystal analyzers to achieve exceptional resolution and sensitivity (Δd/d: ~2x10 -4; typical data collection times: 10–60 minutes). Beamline 11-BM offers a unique mail-in service for rapid access and supports on-site user experiments for non-routine powder diffraction measurements.

Both dedicated powder diffraction beamlines are operated by the Structural Sciences (SRS) Group within the Advanced Photon Source’s X-ray Science Division. More information on SRS beamlines can be found at http://www.aps.anl.gov/Xray_Science_Division/Structural_Science/.

NEEDED: Your APS Workshop Ideas and Invited Speaker Suggestions--Due January 11, 2013!
The 2013 APS/CNM/EMC Users Meeting is scheduled for May 6-9, 2013. The APS Users Organization (APSUO) Steering Committee is now calling for suggestions for APS plenary session speakers and proposals for APS-specific workshops. These proposals should be no more than one page long and include a description of the workshop's scientific or technical focus, a list of suggested speakers (it need not be a final list), and the names of at least two workshop organizers.

Funds will be available to help cover costs associated with workshop organization, but identification of other support would be useful. The workshop schedule will be announced after the first APSUO Steering Committee meeting of 2013.

Have you heard any interesting talks lately or know of someone whose research would make for a fascinating invited talk in the APS plenary session? Please submit their name and a brief description of their possible talk topic. Please submit proposals and speaker suggestions to Connie Vanni (APS User Office) vanni@aps.anl.gov.

New Road Rule at Argonne
In a recent change, the speed limit in all Argonne parking lots has been set at 15 miles per hour. Signs are being posted throughout the Laboratory’s parking areas.

An important reminder: Individuals operating motor vehicles on the Argonne campus are prohibited from using cell phones or other mobile communication devices while driving. The Argonne Protective Force will issue tickets to users who violate this rule.

Remember that the Illinois Motor Vehicle Code applies site-wide at Argonne National Laboratory. Drivers must always yield the right of way to pedestrians who are crossing at marked crosswalks. Additionally, anyone operating a motor vehicle must have a valid driver's license or instruction permit, wear seat belts, obey traffic signs and signals, have liability insurance, and be alert for road hazards.
