MESSAGE FROM MURRAY

Run 2007-2 Restored

As mentioned in my last message, the action of Congress to provide relief for the Department of Energy (DOE) Office of Science budget has reduced the financial exigency under which we at APS have been operating so far this year. As a result, we will reinstate the full run 2007-2 as originally planned (May 30 to August 23, 2007; see long-range schedule at http://www.aps.anl.gov/Facility/Schedule/). I thank you for your patience through these difficult times and for your advocacy efforts, which helped bring about the positive change, and I thank the DOE for allocating a sufficient amount of funding for us to operate adequately.

I look forward to seeing you at our User Week meeting this year--it promises to be a vibrant meeting, with several sessions focusing on the science which will be enabled by future upgrades to APS.

SCIENCE NEWS

1. 2007 Compton Award Shared by Joachimiak and Rosenbaum

The APS and the APS Users Organization are proud to announce that the 2007 Arthur H. Compton Award will be presented jointly to Andrzej Joachimiak and Gerold Rosenbaum. The award committee faced a difficult choice among several outstanding candidates, all of whom have made important contributions to the APS and to science around the world. This choice recognizes the worldwide stature of protein crystallography conducted at the APS, the importance of this field of research, and the major roles played by Drs. Joachimiak and Rosenbaum. The award cites Joachimiak and Rosenbaum for "pioneering advances and leadership in establishing the APS as a premier location worldwide for protein crystallography research."

2. Video Tutorials Ease Learning Curve for Rietveld Analysis in Powder Diffraction

Though unquestionably powerful for determining structures from powder diffraction data, Rietveld analysis poses a significant learning mountain--not just curve--for the novice. APS powder crystallography expert Brian Toby aims to change that by using Internet video to teach the method, especially the nuances of manipulating analysis software. He describes the project in the March 2007 issue of Powder Diffraction.

As Materials Characterization Group Leader in X-ray Operations and Research, Toby is responsible for powder diffraction capabilities in three sectors at APS, including the soon-to-be-completed 11-BM high-resolution and high-throughput powder diffractometer. This instrument will produce a hundred measurements each week on mailed-in samples--so a new model for user training and support is crucial. "We can't help users learn the analysis software if they aren't here, particularly if we are supporting several different research groups every day," Toby says.

Toby saw the power of computer-based audio/video presentations in 2004, when a colleague was unable to attend a conference and sent a video instead. "It was a talk with some very interesting ideas. My colleagues and I replayed that talk several times, as we considered and debated his ideas," he said. "The pause button was of great value!"

Most Rietveld software packages were developed for use by trained crystallographers and are not particularly friendly to the neophyte user. Hand-on workshops are a good way to get started, Toby says, but it's hard to develop an understanding of what can go subtly wrong. Further, many interested people can't get to workshops due to lack of space or funding. And the advanced topics--always the hardest to learn independently--are the very ones that can't be covered in workshops because of time constraints.

That, he believes, is where Internet video can be a big help. With new recording software, videos can show a direct view of the computer screen as the instructor runs the analysis software; audio commentary can accompany the screen video. The result approximates the kind of side-by-side interaction one might have with a mentor. About 30 videos ranging from novice to expert level are presently available from the education section of the APS web site. The new capabilities on beamline 11-BM will be featured in a future issue.

3. Research Highlights

The following are recent additions to the gallery of science highlights available at http://www.aps.anl.gov/Science/Highlights/.

Blood vessel growth: Fluorescence microprobe imaging demonstrated that copper localizes in and near blood vessels in tumor tissue; manipulation of copper levels may limit angiogenesis and thus tumor growth.

Self-assembled block copolymers: GISAXS has revealed a predicted imperfection in the long-range ordering of 2D single crystals self-assembled from 10-nm spherical block copolymers; results relevant to practical applications of block copolymer lithography, for example, patterning of high-density disk drives.

Metallic glasses: Complementary work at different beamlines captured a pressure-induced transition between distinct amorphous states of Ce55Al45, a metallic glass; results relevant to understanding crack resistance of technologically important metallic glasses.

Vanadium superconductivity: Under extremely high pressures, pure vanadium crystals change their shape but do not take up less space as a result, unlike most other elements that undergo phase transitions; results relevant to understanding superconductivity.

4. User Meeting News: Abstract Deadline Extended to April 9; Banquet at Adler Planetarium!

We say it every year, but can it be true that April is here already?? That means it's time to move forward with your plans for the User Meeting. The abstract deadline has been extended to Friday, April 6, to give you a few more days to squeak in your latest results.

This year, in a return to a popular tradition from the early day of  the APS, the user meeting banquet will be off-site at the Adler  Planetarium, on Chicago's magnificent lakeshore. (This venue is made  possible in part by the support of meeting sponsors.) Attendees will  have the chance to see a sky show, enjoy cocktails and exhibits in  The Milky Way, and dine in the Sky Pavillion, which features a  spectacular view of the Chicago skyline.

5. APS Publishes New Five-Year Strategic Plan, List of Future Dedicated Beamlines

On March 7, 2007, the APS released a new strategic plan covering anticipated development in the years 2007 to 2011 at both X-ray Operations and Research beamlines and Collaborative Access Team (CAT) beamlines. The report features a table listing the dedicated beamlines planned for operation by the APS. Other topics covered include
-Scientific opportunities at the APS that will be addressed by emerging new capabilities
-Completion of current construction, upgrades, and optimization
-Essential developments in detectors, scientific software, and optics in support of the scientific capabilities
-Opportunities for leveraging between the CATs and the APS in future developments
-A brief description of planned accelerator upgrades and new insertion devices.

6. Workshop on April 23 to Focus on Optics for Upgrade

The APS Upgrade / ERL Optics Workshop will be held on Monday, April 23, at the APS. The workshop will focus on x-ray beamline optics needs and opportunities in connection with the planned upgrade for the APS. Talks will address the anticipated performance and opportunities of undulator sources, as well as the state of the art for optics fabrication, measurement, and simulation.

There is no cost to attend, but registration for the workshop is required to assure an adequate room size. An e-mail to Linda Shoudis at ljs@aps.anl.gov is sufficient to guarantee registration.

Agenda: http://www.aps.anl.gov/News/Conferences/2007/APS_Upgrade/opticsWS.html.

7. Scientific Advisory Committee Welcomes New Members, Sets Next Cross-cut Review

The APS Scientific Advisory Committee (SAC) convened in its annual meeting at the end of January. In addition to the results of sector reviews conducted in 2006, the committee considered the latest APS strategic plan, including current options for buildout of the remaining sectors. The topic for the 2008 cross-cut review was chosen: x-ray imaging in biology/soft materials. That review will be held Wednesday, January 23, 2008.

9. New Contract Number Required in Acknowledgment

Argonne is now operated under a new contract (see issue 38, article 6) and has a new contract number. This new number should be used in the acknowledgment statement that authors are asked to place in the papers. The text should read as follows:

"Use of the Advanced Photon Source was supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-06CH11357."

Also, please remember to include appropriate acknowledgments of the resources provided by collaborative access teams (CATs) and/or their staff, other (non-CAT) beamline staff, affiliated institutions, and funding agencies.

It is also mutually beneficial to include a statement in the body of the paper noting the location(s) and designation(s) of beamlines (e.g., "...data collected at the X-ray Operations and Research beamline 2-ID-B at the Advanced Photon Source, Argonne National Laboratory").
