Routine Business :
Steve Durbin welcomed the group and asked that the minutes from the October 9, 2004, steering committee meeting be reviewed and approved. The minutes were approved as written.
Murray Gibson gave the group an update on the budget. As of this month, the APS operating budget is $85.23M, up 4.5% from last year. ARIM is at only $1M, down $2.9M from what was anticipated. $2.4M of the $8M facilities increment has been received. Of the ~$5M we will receive as other operating income for 2004, ~$1.5M comes from LDRD, ~$1.3M from CNM-related activities, ~$1.5M from LCLS-related work, and ~$0.5M from proprietary user fees. Recovery of capital money spent on beamline/ID construction for some sectors will add ~$4M to the $5M received for capital equipment in FY04. Extensive budget planning is underway at this time, and it is expected that additional people will be hired to support beamlines, user operations, and engineering.
The next Strategic Planning meeting will be held on August 29 th -- September 3 rd , 2004 in Lake Geneva , Wisconsin . The meeting will focus entirely on new scientific directions for the APS, and is organized as part of the Gopal Shenoy and Sunil Sinha study. There will be three days of parallel workshops and a 2-day summary discussion. This meeting will be the initial planning for Phases III and IV of our 20 Year Plan, which we have named APS 2 . Each sector can be represented by two members at this meeting.
Gibson outlined the SAC Meeting scheduled for next week, January 20 -- 22, 2004. The SAC will present overviews and reports from the Sector Review Panel meeting held previously and will discuss the policies and procedures for conducting proprietary research at the APS. The group will also review Partner User Proposals. Science with Microbeams will be the subject of a cross-cut review planned for Wednesday of next week.
The University of Chicago review was also discussed. Highlights included the tremendous improvement of the parameters of the storage ring over the last two years; the excellent results obtained in various areas, specifically in structural biology and materials science; and the increase in the capacity of the APS with its recent reorganization. Suggestions were made relative to machine performance, such as to explore the possibilities of different types of modes -- more bunches, more current, maximum brightness modes. The review team encourages the development of exotic undulators (superconducting, variable period). Strong support was offered for two initiatives -- Coordination of Accelerator Research at Argonne and the Institute for Advanced Accelerator Research to develop accelerator physics both inside the APS and beyond the laboratory's boundaries. The Low-Energy Undulator Test Line (LEUTL) free-electron laser (FEL) project has produced exciting results in the area of high-gain FEL, but continued operations and improvements should be supported only with external funds. The review group felt that the APS management should be more involved with the macromolecular crystallography CATs. Most of the beamlines are already built, but a coordination should be implemented for robotization to avoid different and incompatible control systems and interfaces. One of the biggest limitations on the utilization of APS beamlines, especially in the materials physics area, is the lack of detector development. It is suggested that the APS take the lead in approaching DOE for detector R&D funding.
Operations Directorate Issues:
Rod Gerig presented an overview of the Operations Directorate and explained how new ideas can be heard, evaluated, and perhaps recommended for implementation. Enhancements currently being discussed include extended straight, pathway to higher current, quiet injection, and special operating modes.
Special Operating Modes:
Glenn Decker discussed the potential symmetric fill patterns. The present default top-up fill pattern has 24 bunches, a 153.4 nanosecond bunch spacing, and the current/bunch @ 102m mA is 4.3 mA. The present default non-top-up fill pattern has 324 bunches, a 11.4 nanosecond bunch spacing, and current/bunch @ 102 mA is 0.3 mA. User requests for devoting a larger fraction of operations days to a given SOM or for a new SOM are discussed at the APS Operations Directorate. AOD solicits input from the PUC on proposed SOM request at least six months in advance of proposed schedule incorporating SOM requests. This process took place for increasing the number of hybrid-singlet mode operation days during the FY04 summer run. Results of partner user feedback will be discussed with AOD and brought to the Operations Directorate for approval. If there are potential adverse effects on user science programs, SAC input could be requested on longer term issues, such as the introduction of new SOM.
Critical Components Update:
Bill Ruzicka reported to the group that Mohan Ramanathan and his team have been and/or will be visiting every sector to acquire up-to-date and accurate drawings and specifications for each critical component. In the very near future, the plan is to continue brief run periods of slightly higher current (100mA -- 110mA -- 115 mA). APS is now reviewing and redocumenting the operating envelope for each critical component. The long-term accelerator plans in the high-current operation area include a commitment to optimizing operations and assessing potential programmatic benefits and implications on beamline operations of higher current operations. The APS requests support from the beamlines in the assessment, while plans for future high-current tests will be discussed at CAT Chat. When the accelerator storage ring goes into a significantly high current mode, APS will support the beamline upgrade efforts required (higher heat load optics).
End of Experiment Response System:
Susan Strasser briefed the group on the new End of Experiment Response system and reminded them that the purpose of the system is to provide regular and immediate feedback to APS and sector managers from APS General Users on their beam time experience to identify strengths and weaknesses for future planning purposes. The form can be completed on site or remotely by any experimenter listed on the ESAF for the experiment. All users (General Users, Partner Users, CAT members, staff) can complete an EEF; however, reminder e-mails will be sent only to General Users. The form consists of two parts -- 7 APS-specific questions and sector-specific questions, if desired (for run 2004-1, only sectors 18, 33, and 34 have sector-specific questions). Both sector and APS personnel can view responses to APS-specific questions, while only designated sector personnel can view responses to sector-specific questions.
During the lunch break, representatives from sectors gave overviews of their sector to help the steering committee stay informed about user issues and help the group get a more complete picture of the user enterprise. Presenters at this meeting and the sector they represent are shown below:
- Sector 5 -- John Quintana
- Sector 9 -- Thomas Gog
- Sector 13 -- Mark Rivers
- Sector 15 -- Jim Viccaro
- Sector 16 -- David Mao
- Sector 33/34 -- Paul Zschack
User Meeting Plans -
Mark Rivers discussed the progress made so far on the 2004 Users Meeting scheduled for May 4-6, 2004. The First Center for Nanomaterials User Meeting will be held on May 3rd. The group felt that it would be good to again have the poster session out on the floor as was done last year. A wine and cheese reception could be held in conjunction with this session.
A listing of suggested workshops was reviewed by the group, and will be discussed further, along with possible workshop organizers.
The banquet will consist a pig roast at the Guest House. It will be held in a tent and will feature bluegrass music.
A Young Investigator Award was discussed. This award would be for a person who is within two years of having received his or her Ph D. John Rose, Sunil Sinha, and Steve Durbin will serve on the Young Investigator Award selection committee.
Within the next week, the workshop and organizer plans will be finalized, the web site will be up, and we'll announce the Young Investigator Award, and a preliminary list of guest speakers will be started.
Carol Thompson, Malcolm Capel, and Gene Ice have been appointed to serve as the APSUO nominating committee. The committee will send a slate of names to other Steering Committee members for review prior to finalization.
Next Meeting :
The next APSUO Steering Committee Meeting will be held on Thursday, May 6, 2004, as part of the 2004 Users Meeting for the APS.
