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

We are very pleased with the success of the Twelfth Users Meeting for the APS last month, and I want to thank all who attended, and especially the APSUO for the organization. Particularly important to me was the student attendance. There were many impressive student posters, including several from alumni of the National School on Neutron and X-ray Scattering. Another highlight of the meeting was a kickoff of the Shenoy-Sinha study panel of new scientific directions for the APS; see story 3 below. Your input into this important exercise is encouraged.

Fiscal year 2003 at the APS ends September 30, 2003. Congress passed the 2003 budget late this year, and so we have only recently learned our final budget. The President's request for APS in FY 2003 was $91.3 million, and our final allocation appears to be about $90.9 million. The cut is a little more than it appears, because included in our final budget are funds transferred to APS, effective January 1, 2003, for BESSRC operations. However, the final budget is consistent with reductions of between 1-2% applied by Congress across the Office of Science. The President's budget request for APS in FY 2004 is $94.5 million. APS will need at least this budget level to fulfill all our commitments, especially enhanced support for beamline operations. Discussions are ongoing with the DOE Office of Basic Energy Sciences to identify future funds to support the activities included in our 20-year planning proposal (http://www.aps.anl.gov/aps/downloads/20030223-roadmap.pdf), which was strongly endorsed by the Basic Energy Sciences Advisory Committee.

The APS has developed a new policy for user participation, the "Policy for Access to the APS by Partner Users," which can be found on the web at http://www.aps.anl.gov/user/policy_procedures/partner_users/access_policy.html. We identify a new class of users--partner users--to complement general users. A partner user is one who is engaged in scientific research, just like a general user, but whose work directly benefits the facility and other general users. Collaborative Access Teams are important examples of partner users, but we have added flexibility. You can find more information below; especially, note the call for partner user proposals of limited scope for the 2003-3 run.

2. Twelfth Users Meeting Draws Record Crowd!
(Contact: Susan Strasser, strasser@aps.anl.gov)

Almost 500 current, new, and prospective users attended the Twelfth Users Meeting for the APS. The three-day event (April 29 through May 1) featured a wide variety of workshops, scientific talks, posters, vendor exhibits, and social events. Workshops all day Tuesday and on Thursday afternoon included three sessions on different aspects of nanoscience, three sessions on imaging, two sessions on high-throughput macromolecular crystallography, a session on in-situ chemistry, and presentations by alumni from the National School on Neutron and X-ray Scattering. More than 100 posters (30 from students) were available for viewing throughout the meeting, and lively discussion characterized the two scheduled poster sessions. If you couldn't be there, check out the photo gallery to see what you missed. 

During the meeting's opening session, Pat Dehmer, Director of the DOE Office of Basic Energy Sciences; Paul Doucette from the Washington Office of Illinois Representative Judy Biggert; and Sue Ginsberg from the American Physical Society provided attendees with different perspectives from Washington. Their common message, however, was the importance of involvement by scientists in the process that shapes our national scientific agenda. Their talks were followed by highlights from Bev Hartline, Interim Director of the Center for Nanoscale Materials being established at Argonne, and APS Director Murray Gibson's report on APS progress since the last APS Users Meeting in October 2000, together with his thoughts on the future. The morning session ended with the presentation of the sixth APS Arthur H. Compton Award to Martin Blume, Doon Gibbs, Namikawa Kazumichi, and Denis McWhan, and the Compton Lecture delivered by Martin Blume. (See Issue 20 of APS User News-at-a-Glance for more information on the Compton Award.)

The Wednesday afternoon and Thursday morning scientific sessions featured seven talks on cutting-edge APS science. Mark Westneat from The Field Museum of Chicago discussed insect respiration as identified through x-ray imaging. John Hill from Brookhaven presented work on electronic exitations in strongly correlated electron systems. Andrew Ferguson from the University of Texas Southwestern Medical Center talked about work involving the structure and possible mechanism of action for FecA, a membrane transporter protein. David Tiede from Argonne's Chemistry Division discussed chemists' use of synchrotron radiation to examine the structure and dynamics of functional molecular assemblies. Carol Thompson, Northern Illinois University, described the use of x-ray scattering to understand the formation and dynamics of nanoscale ferroelectric domains. Gayle Woloschak, Feinberg School of Medicine at Northwestern University, explained the biology underlying the creation and use of chemical-biological hybrid nanocomposites that can be introduced into cells, targeted to specific subcellular sites, and used to initiate intracellular processes or carry out biochemical reactions. Finally, Ben Larson described sub-micron resolution three-dimensional x-ray structural microscopy.

Other meeting highlights included the Wednesday evening "Synchro de Mayo" fiesta, where participants sampled a large variety of outstanding Mexican specialties, enjoyed the music of a live mariachi band, and engaged in spirited conversation. The filled-to-capacity vendor exhibit area provided opportunities for users to learn more about new instruments and technologies, and the final session of the meeting, the round-table discussion on new scientific directions for future APS beamlines (see story below), left users thinking seriously about exciting new possibilities.

A limited number of program books from the meeting, which contain abstracts from the scientific talks, posters, and some workshop presentations, are available on request from the APS User Office (uao@aps.anl.gov).

3. Seize the Moment: Input Needed by May 30 on New Scientific Directions for the APS
(Contacts: Gopal Shenoy, gks@aps.anl.gov, and Sunil Sinha, ssinha@physics.ucsd.edu)

Is there science that you'd like to do at the APS that isn't possible now? Here's your chance to make it possible: send your suggestions by June 30 to the newly established Study Panel on New Scientific Directions for the APS. 

Formed under the auspices of the APS Scientific Advisory Committee (SAC) and co-chaired by Gopal Shenoy and Sunil Sinha, the panel is charged to develop a comprehensive foundation for future science at the APS, using user input. The composition of the panel will be determined by the themes that emerge from ideas provided by users. At the Twelfth Users Meeting, Shenoy and Sinha outlined the process they will follow, and several presenters gave users a brief taste of some of the intriguing possibilities that have already been suggested. 

The co-chairs will select five to eight broad topics for further consideration and add panel members with expertise appropriate to those topics, with guidance from the SAC. Then, in late 2003 and 2004, the panel will conduct workshops on each topic to gather more detailed input and finally present a report to the SAC within a year.

Shenoy and Sinha have already contacted many users and other scientists and have already amassed many interesting suggestions, which were distributed at the Users Meeting (for copies contact Bonnie Meyer, bsm@aps.anl.gov). Please send additional suggestions in a suitable format (e.g., a short writeup, viewgraphs) to Bonnie Meyer (bsm@aps.anl.gov) by June 30.

4. APSUO Steering Committee Welcomes New Members, New Chairman
(Contact: Susan Strasser, strasser@aps.anl.gov)

On Thursday, May 1, at the end of the Users Meeting, the APSUO Steering Committee met briefly over lunch to welcome the newly elected members and thank those finishing their terms. Murray Gibson thanked outgoing chairman Paul Zschack for his many valuable contributions during a time of significant change within the APS. Vice-Chairman Stephen Durbin then moved into his new role as Chairman. Steve is the first "repeat" chairman of the APSUO Steering Committee, having served in that capacity from May 1991 to October 1992. 

The new members, elected by users through online voting before and during the meeting, are
-Malcolm Capel, NE-CAT
-Julie Cross, PNC-CAT
-Stephan Ginell, SBC-CAT
-Gene Ice, Oak Ridge National Laboratory
-Mark Rivers, GeoCARS
-Carol Thompson, Northern Illinois University

Leaving the Steering Committee were John Budai, Pulak Dutta, Dean Haeffner, Steven Muchmore, Brian Stephenson, and Amy Rosenzweig. Their contributions are much appreciated. Continuing members are Stephen Durbin (Chairman, Purdue University), Lin Chen (Argonne), David Cookson (ChemMatCARS), Lisa Keefe (IMCA-CAT), John Rose (University of Georgia), Sunil Sinha (University of California, San Diego), and Paul Zschack (ex officio, UNI-CAT). Brief background information for all committee members is posted on the APS web site under User Info > Committees > APS Users Organization > List of Steering Committee Members, or directly at http://www.aps.anl.gov/user/committees/apsuo/members/home.html.

5. New Partner User Council Holds Inaugural Meeting. 
(Contact: Susan Strasser, strasser@aps.anl.gov)

The kick-off meeting for the new APS Partner Users Council (PUC) was held on April 29 in conjunction with the final meeting of the APS Research Directorate. Constituted as advisory body to the APS, the PUC includes a representative from every sector, appointed by the sector management. However, representatives from each sector operated by the APS (facility-managed beamlines) serve in a non-voting capacity. According to the bylaws/charter adopted that night, the Council will provide advice and recommendations to the Associate Laboratory Director for the APS in matters affecting current and future beamline operations, APS facility development, and the special APS-to-Partner User relationship. The PUC inherits all the roles of the Research Directorate, but now also includes ex-officio representation on the APS Scientific Advisory Committee. Jim Viccaro, The University of Chicago/CARS, was elected as the first Chair. John Quintana (DND-CAT/Northwestern) agreed to serve as the PUC representative at the weekly APS Operations Directorate Meeting, and Roy Clarke (MHATT-CAT/University of Michigan) was asked to attend the upcoming Sector Review Panel meetings on June 2-5, 2003, as the ex-officio PUC representative. The Council will meet on the same schedule as the former Research Directorate, with its next meeting scheduled for mid-July.

6. APS Seeks "Limited-scope" Partner User Proposals
(Contact: Susan Strasser, strasser@aps.anl.gov)

Short proposals are being solicited from individuals or groups wishing to establish limited-scope Partner User arrangements with the APS. These proposals are due June 1, 2003 for the fall run (Run 2003-3).

A Partner User is defined as an individual or group that contributes to the facility or user community beyond simply performing good scientific research. A typical Partner User may propose to develop a new capability or beamline; design, build, and operate a full sector; build a new user community; engage in outreach activities; or perform other activities outside the scope of the APS General User Program. Limited-scope partnerships are typically those that require no more than 15% of the beam time on a beamline. Further definition of Partner User arrangements (limited, intermediate, and extensive scope) can be found in the Policy for Access to the Advanced Photon Source by Partner Users (4/24/03). Requirements for the submission of Letters of Intent (LOIs) and short proposals are detailed in the Procedures for Access to the Advanced Photon Source by Partner Users (4/28/03).

Short proposals for limited-scope partnerships to be considered for beam time in fall run of calendar year 2003 are due by June 1, 2003, with decisions expected no later than August 15, 2003. Letters of Intent for partnerships of more extensive scope will be considered for beam time beginning in 2004 and beyond. 

Note also that short proposals for partnership agreements can only be submitted on CAT-operated sectors where more than 25% of the beam time is available for General Users. For the fall run of calendar year 2003, those beamlines are 7-ID, 8-ID, 20-BM, and all beamlines in Sectors 1 through 4.

For further information, contact Susan Strasser (strasser@aps.anl.gov, 630.252.5981) in the APS User Office or go to the following web address: http://www.aps.anl.gov/user/policy_procedures/partner_users/.

7. Ruzicka Appointed Director of the APS Operations Division
(Contact: Murray Gibson, jmgibson@aps.anl.gov)

The APS is pleased to announce the appointment of William G. Ruzicka to the position of Director, Advanced Photon Source Operations Division (AOD), effective April 21, 2003. Bill brings extensive experience in operation of accelerator-based user facilities from the Intense Pulsed Neutron Source (IPNS) at Argonne, where he served as Operations Manager for 11 years. Bill has over 30 years of experience in professional engineering and facility operation. Through his time at IPNS, he has developed an excellent perspective on national user facilities operations and experience in operations management. The search committee was particularly impressed by Bill's open and effective leadership style, his decisiveness, and his customer orientation towards users. Bill fills the position vacated by the unexpected death of Antanas V. Rauchas in November 2002. Roger Klaffky, who played an invaluable role for APS as interim director of the AOD, has returned to his position as Associate Division Director of the AOD. 

8. Operations Update
(Contact: Bill Ruzicka, wruzicka@anl.gov)

During Run 2003-1, the APS delivered 1599 hours of beam, with beam available 97.1% of the scheduled time; mean time between failures was 35.5 hours. Several improvements to storage ring operations were implemented during this run. The x-ray beam position monitor on the 34-ID beamline was used in a feedback/feedforward system to correct xbpm position offsets versus insertion device gap. This strategy improves the pointing stability of the x-ray beam by an order of magnitude. Feedforward will be operational on several additional insertion device beamlines when the APS resumes operation in June and will be added to more beamlines after 48-hour studies periods. During the last week of Run 2003-1, the storage ring orbit stabilization system performed an electron-beam orbit correction 20 times per second, which is more than a factor of 40 faster than previous correction rates. In effect, this improvement removes orbit motion caused by changes in insertion device gap and generally reduces the ambient noise seen on the beam. Run 2003-1 also incorporated a six-day period of 324-bunch operation. This non-top-up operational mode has a lifetime greater than 75 hours while maintaining the standard low-emittance lattice.
