First APS/User Retreat: A Success!
Dates Set for the Twelfth APS User Meeting
Next Independent Investigator Proposals Due July 1, 2002

APS/User Strategic Planning Meeting: A Success!
atmosphere of collegial interaction characterized the first
APS/User Strategic Planning meeting as 115 APS staff members
and users gathered to discuss the future. Plenary sessions
focused on the APS mission and goals, the future of the
Collaborative Access Team System, future innovations with
third-generation sources, and operational funding for
beamlines were interspersed with break-out sessions on
technical issues, user support, Independent Investigator
access, publicity/public relations, communication, advocacy,
and compliance with mandates. Serious discussions,
innovative suggestions, and thoughtful analyses, as well as
humorous interchanges, created a mood that fostered the
building of consensus about future directions. For a
detailed look at specific recommendations and action items,

Set for the Twelfth APS User Meeting
calendars now for the week of April 28 through May 2, 2003,
for the Twelfth User Meeting for the APS. APS Users
Organization (APSUO) Vice-Chair Steve Durbin is the General
Program Chair, and he and the APSUO Steering Committee have
already begun to plan for this exciting event. Included in
the festivities will be the presentation of the sixth Arthur
H. Compton Award, science talks, a poster session, a vendor
exhibit, and several social events. A series of topical
workshops will be held in conjunction with the meeting, and
at the general business meeting, six new members will be
elected to the APSUO Steering Committee
Independent Investigator Proposals Due July 1,
Investigator (II) proposals for the last user run of
calendar year 2002 (October 9 - December 19, 2002) are due
on July 1, 2002. Beginning with the run, four more CATs will
be accepting II proposals (Bio-, IMM-, MHATT-, and MU-CATs),
which brings the number of CATs that provide II time to 13.

Highlight: "Edema Factor: Revealing the Structure
of an Anthrax Toxin"
Edema factor (EF) is one of three toxins that make anthrax a deadly biohazard. Researchers using the BioCARS and Structural Biology Center beamlines at the Advanced Photon Source and beamlines X25 and X4 at the National Synchrotron Light Source have determined the three-dimensional structure of EF. This discovery provides important new information that may lead to the design of pharmaceuticals to counteract the effects of bacterial toxins such as anthrax. Details of the research were published in the January 24, 2002, issue of Nature. Further details can be found on the following
to Submit Research Highlights
Highlights of research carried out at the APS are posted prominently on the APS Web home page. They are also useful in many ways, in particular when the APS is asked to inform the DOE and ANL management about current APS science.
If you would like to submit published research for consideration as an APS highlight, we will be delighted to make use of the material you send. For examples of current highlights, go to http://www.aps.anl.gov/highlights/hilitesarchive.html.
submission, we need the following:
Your name and e-mail address

A number of informative and enjoyable events will take place in the coming weeks:
The annual APS summer picnic for APS employees, APS users, and their families will be held on Friday, June 28th at Argonne Park. While the children enjoy such events as a water-balloon toss, face painting, application of temporary tattoos, and a moonwalk, the adults can enjoy live music from "The Storm." Just as the variety in entertainment is suited to please all, the food is as well: Athenian-style chicken, pasta with plum-tomato or meat sauce, Italian sausage, baked ham, hot dogs, garden and village salads, fresh fruit, and sandwich rolls. With the picnic running from 5:00 pm until dusk, there should be plenty of time to enjoy and taste everything. Tickets are $8.00 for those 13 and older ($12.00 after June 25), $3.00 for children 6-12 years ($5.00 after June 25), with free admission for children 5 years and younger. Tickets can be purchased in the APS User Office or from the following APS Spectrum Club members: Barb Dalton, Cathy Eyeberger, Jill Fredericks, Cheri Giacomi, Marvin Kirshenbaum, Laura Morisco, Anne Owens, Jane Pransky , Cyndi Salbego, and Marcia Wood.
On July 10, 2002, at 3:00 pm, you'll find Dr. Thomas Russell, University of Massachusetts Amherst, at the Advanced Photon Source giving the July APS Colloquium Lecture. Entitled "Direct Assembly of Polymers from the Nanoscopic to Microscopic," Dr. Russell's talk will provide an overview of the mechanisms that govern the spatial assembly of polymers in thin films. A listing of future talks in this series can be found at the following Web page: http://www.aps.anl.gov/conferences/APSColloquium/aps_colloquium.html.
Structural Biology Center (SBC-CAT), in conjunction with the
Midwest Center for Structural Genomics at Argonne National
Laboratory, is sponsoring a four-day hands-on workshop from
November 20-24, 2002. This workshop is intended to
demonstrate experimentally the unique capabilities available
at third-generation synchrotron source beamlines through
hands-on data collection, analysis and structure
determination. The experiments will be complemented by short
seminars and discussions with experts. Further information
can be found at the following Web site: http://www.sbc.anl.gov.
The second run of calendar year 2002 has begun and will continue through early September. As in the last run, a machine studies shift has been set aside, on June 24, to study beamline operation under increased flux conditions. The storage ring will operate for a time at 130 mA to allow beamline personnel to analyze the impact on beamline elements. Additional machine studies are planned to further investigate potential improvements in beam stability and other stored beam characteristics.
run of the calendar year was completed on April 28. This was
the longest single user run in APS history (providing 1872
hours of user beam time), while simultaneously establishing
a new user run record for availability of 97.1%. As a
result, records were also broken in the maximum integrated
current delivered (182.2 A-hrs) and due to the reliability
of top-up operation, a record was achieved in the average
current for the run (97.4 mA). The success of this run sets
a new standard for future operation at the APS.
