Message from Murray
(Contact Murray Gibson, jmgibson@aps.anl.gov)

Greetings from cold but sunny Chicago ! This year is the 10th anniversary of first light from the APS--a major milestone that we will celebrate in several ways. The main celebration will occur at our annual Users Meeting in May, but we will have a small party for employees and local users close to the date of the actual anniversary, March 26th. Thanks to the work and success of you, our users, and the dedication of APS employees, we can all be very proud of the achievements of APS. The number of experiments carried out at the APS and their scientific impact grow every year, and new capabilities are coming online every year. The accelerator is operating at unprecedented reliability and with exceptional performance. Furthermore, we have developed strategic plans for the future, which will enable us to better serve existing user communities and develop new ones. The long-term future is bright.

However, we face difficult challenges in the near term due to constrained federal budgets. Budget difficulties are shared by the broader scientific community, but the fixed costs and needs of a large user facility like APS are demanding. The proposed President's budget for APS in fiscal year 2006 will put immense pressure on us. If our funding is authorized by Congress at this level, it will not be possible for us to avoid reduced operating hours and reduced access to beamlines. I understand that the APS Users Organization will be working with other U.S. facility user groups to share with you opportunities to advocate for the needs of our facilities. Please take these activities seriously. The primary way for us to assure the long-term health of the scientific enterprise is to make sure that society is aware of its importance to the economic security of our nation.


1. Schmahl, Kirz Receive Compton Award for Contributions to X-ray Microscopy

The Advanced Photon Source (APS) and APS Users Organization (APSUO) are very pleased to announce that the 2005 Arthur H. Compton Award is given to Günter Schmahl and Janos Kirz for pioneering and developing the field of x-ray microscopy using Fresnel zone plates. The awardees will be honored on May 4 at the APS Users Meeting.

Because of the leadership of Schmahl and Kirz over the last 30 years, x-ray microscopy has evolved into a powerful method for the study of nanoscale structures and phenomena in many areas of science. Their achievements have opened up productive research avenues in biology, polymers, electronic nanostructures, magnetic materials, meteoritics, and environmental sciences. “Günter Schmahl and Janos Kirz have created a whole new field through persistent efforts over many years,” says Harald Ade of North Carolina State University . “The impact of their work will only keep growing as nanotechnology becomes more and more important.”

2. Research Highlight: X-ray Movies Reveal Muscle Motion for Insect Flight
(Contact: Thomas Irving, irving@iit.edu)

With small-angle diffraction techniques and a live fruit fly on a string, a team working at BioCAT (sector 18) has made in vivo x-ray movies of the muscles used in insect flight. The experiment yielded molecular-level information on muscle structure, which may help clarify how insect flight muscles generate great power at high frequency. The study may also provide a new model for studying the behavior of other oscillatory muscles, including human heart muscle.

In this study, a Drosophila fly was suspended in the x-ray beam, and a dynamically simulated visual field tricked the suspended fly into maintaining a stable flight—and therefore a steady wingbeat pattern. Its flight was optically monitored so that x-ray exposures could be timed to the wingbeats.

The data show that the structure of the thick filaments changed, as did the interaction between the muscle proteins actin and myosin, over the course of the wingbeat cycle. These changes may help explain how the muscle stores energy for the next wingbeat and how the next contraction is triggered. According to lead researcher Tom Irving of the Illinois Institute of Technology, “We are now in a position to relate muscle power output to changes in molecular structure.”

3. Local Special Interest Groups Help Users Overcome "Geography" and Share Interests Info, Resources
(Contact: Susan Strasser, strasser@aps.anl.gov)

In the last few years, a new avenue of communication has begun developing at the APS: the self-organizing special interest group. Current groups focus on high-pressure studies, small-angle scattering, tomography, and x-ray absorption spectroscopy. Each group has its own style, but all are motivated by the desire to provide a forum for users and staff from around the ring to share experiences and idea and discuss needs. Contact information is on the APS website at the URL below. If you form a new group and want to be listed on that site, please contact Susan Strasser.

4. User Announcement: Workshop on New Neutron Technique for Membranes and Films
(Contact: Gian Felcher, felcher@anl.gov)

Gian Felcher (Argonne National Laboratory) and Roger Pynn (Los Alamos National Laboratory) announce a workshop, “Probing complex fluid membranes and films with neutron spin-echo,” to be held August 14-17, 2005 at Indiana University , Bloomington , Indiana . A new development of neutron scattering broadens considerably the range of measurements of in-plane structures in thin films. Among the problems that can be addressed by the new methods is the determination of the structure and behavior of membranes and other thin macromolecular films. The purpose of the workshop is to bring together the membrane and the scattering communities to discuss the relevant issues.

5. 2005 Scientific Advisory Committee Meeting Held in January
(Contact: Susan Strasser, strasser@aps.anl.gov )
(Info: http://www.aps.anl.gov/Users/Meeting )

The 2005 meeting of the APS Scientific Advisory Committee (SAC), held January, 25-27, 2005, began on a solemn note as members paid tribute to retiring SAC member Howard Birnbaum, who died unexpectedly on January 24. Dr. Birnbaum was not only a founding member of the SAC, he was also a founding member and Chair of the predecessor APS review body, the Program Evaluation Board. 

The full SAC meeting included reports from the chairs of review panels for the 10 sector reviews conducted in 2004, formulation of recommendations to the APS for these 10 sectors, discussion of the APS and the XOR strategic plans, discussion of the spectrum of APS user access modes, and a “cross cut” review of research that requires the pulsed structure of the APS x-ray beam. Full minutes of this meeting can be found at http://aps.anl.gov/About/Committees/Scientific_Advisory_Committee/2005/Minutes.html. A separate report on the cross-cut review is currently being prepared.

The meeting also included recognition of the three other retiring SAC members: Paul Peercy, Kathy Taylor, and Wayne Hendrickson. Peercy and Taylor both served for two years as original members of the SAC. Like Howard Birnbaum, Wayne Hendrickson served as a founding member of both the SAC and the Program Evaluation Board. The APS will miss the service of all of these retiring members. Four newly appointed SAC members began their two-year terms on February 1, 2005: Russell Chianelli ( University of Texas at El Paso ), Jennifer Doudna ( University of California , Berkeley ), Katherine Faber ( Northwestern University ), and Miles Klein ( University of Illinois at Urbana-Champaign).

Full information about all SAC members, as well as a photo, agendas, and minutes of SAC meetings can be found at http://www.aps.anl.gov/About/Committees/Scientific_Advisory_Committee/ .

8. Electrical Safety Update
(Contact John Carwardine, carwar@aps.anl.gov)

We would like to remind all APS users that you must be trained and authorized before performing electrical work. Beamline staff have received guidance about the training and qualification requirements for nonresident users, and you may be asked to renew your training or complete additional courses. A recent user safety update gives an overview of electrical safety issues, including a definition of “working hot” (see URL below). Working hot is not permitted at APS except under limited circumstances. Please contact your floor coordinator or ES&H coordinator if you have questions or need clarifications.

The APS Electrical Safety Committee has been developing safe working practices for performing electrical work on the experiment floor. If they are approved, authorized resident users will have more flexibility to perform electrical hot work as necessary. Until they are approved, however, any electrical hot activities must be reviewed and approved prior to starting work, including obtaining a working hot permit. By design, only a limited number of APS employees are authorized to approve working hot permits. If you need to perform electrical hot work, please contact your floor coordinator or ES&H coordinator for assistance.
