MESSAGE FROM MURRAY
Last month saw temporary restoration of funds by the U.S. Congress that provided major relief for APS, allowing us to restore the 2008-03 run and avoid the need for staff layoffs in October. While we are very grateful for this, the operations relief is short-term and it remains essential that our steady-state budget increase next year. Thanks to the temporary relief, we will at least be able to delay any precipitous actions until the passage of the congressional fiscal year 2009 budget, expected in the spring. While continuing to strongly advocate the case for needed increases, we must also be prepared for difficult scenarios. Within APS we are engaged in a detailed “bottom-up” analysis of our budget needs for fiscal year ‘09. We will engage the user representatives (APS Users Organization and Partner User Council Executive Committees) in the later stages of our scenario planning.
APS Renewal planning is going ahead full steam, and I am grateful to the many users who are contributing their ideas. The Renewal offers a real opportunity to advance the capabilities of APS to better address your scientific needs. Please read article #2 below about ways to contribute to the planning.
You will read below (article #6) that Gabrielle Long, who has served for five years at the head of our XOR beamlines, has stepped down as director of the X-Ray Sciences Division (XSD) to return to research. Gabrielle has done an outstanding job, and to replace her we will carry out a broad open search. A search committee is being formed that will be chaired by Denny Mills, APS Deputy Director for X-Ray Science, including representatives from outside APS and Argonne . Please contact Denny (firstname.lastname@example.org) if you have nominations for the next division director of XSD. While the search is ongoing, I have full confidence that Mark Beno, the interim XSD Division Director, and George Srajer, the Associate Division Director of XSD, will keep the division thriving.
The first x-ray beam was successfully delivered to a new coherent x-ray diffraction microscope at 2-ID-B at 4 a.m. Saturday, July 12, 2008. This exciting instrument was brought to APS through a partner user proposal (PUP-74) with the University of Melbourne and La Trobe University, which are both located in Melbourne in the state of Victoria , Australia . The state-of-the-art end-station instrument (designed and constructed by Xradia, Inc. and La Trobe University) blends the advantages of scanning x-ray microscopy for studying extended specimens with high-resolution imaging by coherent diffractive imaging (CDI). CDI is well suited to structural study of thick, non-crystalline samples without the resolution limitations of x-ray lenses. The new CDI instrument offers high-precision nanometer-scale sample positioning with 3D tomography capability and will enable new scientific applications in biological and materials sciences.
Commissioning of the instrument proceeded smoothly and first light was achieved by the second day of the run thanks to the tireless effort of many people, including Garth Williams (University of Melbourne); Jesse Clarke, Andrew Peele, and Mark Pfiefer (La Trobe University); Benjamin Hornberger and Tobi Beetz (Xradia Corporation); Dana Capatina, Emil Trakhtenberg, Russ Otto, Kevin Knoerzer, and Greg Wiemerslage (APS Mechanical Engineering and Design Group); Kris Mietsner and Bill Jansma (APS Survey and Alignment Group); Steve Downey (APS Site Operations Group), Rod Salazar, Greg Banks and Van Nguyen (APS Safety Interlocks Group) and Ian McNulty, Chris Roehrig, and Ed Wrobel (Advanced Photon Source X-ray Imaging and Microscopy Group). This is a great example of a successful partner user collaboration. More information about partner user proposals (PUPs) can be found at the Partner User web page.
As outlined in earlier presentations (talk by Dennis Mills, May 5, 2008, Users Week; talk by Paul Fuoss, June 25, 2008, operations monthly meeting) and a User News article (issue 47), the APS is undertaking a comprehensive process to develop a plan for beamline renewal over the next 5 to 10 years.
The APS wants to involve users directly in this planning, so to help you navigate the process, this article outlines the goal, people involved, process and timeline, resources on the web, and how you can participate. For details on all these areas, see the renewal web site, http://www.aps.anl.gov/Renewal/. All users are invited to contribute their viewpoints and suggestions at any time in the process—the earlier the better, however!
The initial end product of the current effort will be a science-case white paper (preparatory to a major equipment proposal) to be presented to the Department of Energy toward the end of this calendar year. Because at this stage the proposal is for "beamline renewal," the emphasis is on beamline optics, detectors, and insertion devices, rather than major changes to the accelerator or the ring as a whole. Details of instrumentation and implementation will be developed in the next phase, after the white paper is completed.
The process is being guided by the APS Renewal Steering Committee, chaired by Dennis Mills, and by the more than 60 members of 10 "science teams" (listed with their chairs):
- Condensed matter and material physics (Sam Bader, Argonne )
- Chemical science and engineering (team currently being formed)
- Engineering applications / applied science (Gene Ice, Oak Ridge Nat'l Lab)
- Fundamental interactions in chemical, atomic, and molecular physics (Stuart Rice, U. of Chicago )
- Geological, environmental, and planetary (Neil Sturchio, UIC)
- Life sciences (Lee Makowski, Argonne )
- Macromolecular crystallography (Tony Kossiakoff, U. of Chicago )
- Materials science and technology (Paul Evans, U. of Wisconsin-Madison)
- Polymers/soft materials (excluding macromolecular crystallography) (Ken Shull, Northwestern U. )
- Surfaces, interfaces and thin films (Paul Fenter, Argonne )
Steering committee members are listed on the main APS Renewal web page; for science team members, follow the link "Science Teams."
The science teams and their chairs were identified by the steering committee, who also selected team members from a pool of volunteers who responded to an invitation sent to the entire user community on May 28. The response to this call was so overwhelmingly positive that we had more volunteers than team slots. A big thank-you goes to all who expressed interest! And we still want your input: see below for how you can participate.
The science teams have been given a specific charter to prepare a scientific case that defines how upgrades to beamlines (optics, detectors, insertion devices, end-station instrumentation, and software) and the facility will enable new and cutting-edge science and how these scientific developments will impact the field. The drafts will be presented at a meeting of the team chairs with the APS Users Organization (APSUO) Steering Committee and Partner User Council (PUC) and further discussed at a two-day, off-site meeting in October. The October meeting is open to interested users through an application process (space is limited at the meeting venue). The science teams and the Renewal Steering Committee will merge all contributions into the final white paper, which will be reviewed by the APS Scientific Advisory Committee. The timeline for the process is as follows:
August 4 Half-day meeting for science team chairs September 12 Applications due for October meeting September 15 Science case drafts due from science teams September 17 Chairs present science cases to joint meeting of APSUO and PUC Late Sept. October meeting applicants notified of acceptance October 20-21 Off-site meeting December White paper due to DOE
An effort on upgrading the accelerator will proceed in parallel with the rewewal. The hope is that once the renewal projects are underway, the APS can begin to request funds to support research on options for the accelerator.
So that the science teams are able to set their work within the full context of plans for the APS, several resources are available through the home page APS Renewal web site:
- Technical contacts (listed under the Science Teams link). Certain individuals have been designated as the point of contact for the science teams in specific technical areas. For example, "technique coordinators" have been identified to answer questions about future capabilities in specific techniques, e.g., full field imaging or high-energy studies. Other contacts will answer questions about technical support, issues behind the shield wall, and facility infrastructure.
- Existing beamline and accelerator upgrade proposals. These proposals were received from beamline scientists (APS and CAT) and APS accelerator staff in response to a call earlier this year. These proposals indicate the directions that staff at the facility find exciting.
- Existing letters of intent for new beamlines. These proposals are in various stages of approval and serve to reflect the full context of long-term beamline plans.
- Options for an APS Upgrade. This table, and associated material, outlines the major long-term options for changing the accelerator, an effort labeled APS 2020. These options were generated in a planning process in 2007.
Participation from all levels and all disciplines within the user community is encouraged. There are four avenues by which you can contribute:
- Contact the science team chair in your discipline (click team name)
- Join the science team mailing list (click team name)
- Contact a member of the APSUO Steering Committee or PUC (or the representatives to the Renewal Steering Committee, Paul Fuoss and Denis Keane, respectively)
- Apply to attend the October offsite meeting
Please don't hesitate to contribute through any or all of these channels to communicate your vision of future possibilities.
The first cross-cut review of geological, environmental, and planetary (GEP) science at the APS was held on July 9–10, 2008. This review, conducted under the auspices of the APS Scientific Advisory Committee (SAC) and chaired by APS SAC member Glenn Waychunas, was designed to determine the scientific impact of this area of research at the APS, assess its scope, and evaluate the suitability of available resources. This review was the first in a series that will look at eight different science areas over a three-year period to enable the SAC to adequately advise APS management on future directions.
The review consisted of an overview presentation describing the resources (instrumentation and techniques) available for this area of research on all APS beamlines, as well as selected short highlights. The overview was followed by presentations highlighting research programs and/or research projects at specific beamlines that typically support 25% or more of their research in geological, environmental, and planetary science. A poster session in which all beamlines hosting GEP science were invited to participate provided additional information to reviewers. All of these sessions were open to the APS user community and staff. Finally, this review session also included specific executive session management reviews for the seven beamlines on which the majority of GEP research is hosted.
The review report is currently being finalized. However, Review Chair Waychunas summarized the consensus of the committee as follows: "The geoscience research at the APS is on the cutting edge in many areas, and excellent in most areas. Particularly notable are the studies in high-pressure earth materials, and the new tools and techniques being developed to extend investigations into deep earth and planetary interior chemistry. Biogeochemistry and low-temperature geochemistry are also well represented with important developments in several areas, including characterization of specific and unexpected contaminant phases at Hanford tank sites, new findings in microbial redox processing of contaminated sediments, and new information on the reactivity and surface chemistry of common but incompletely understood iron oxide phases. Besides their importance to earth systems, these studies reach beyond geosciences into unplumbed areas of the physics and chemistry of materials and the special properties conferred on nanomaterials by virtue of their high surface areas."The next cross-cut review, covering atomic, molecular, optical, and chemical sciences will be held on November 5–6, 2008, and is being chaired by SAC member Michelle Buchanan.
A joint meeting of the APS Partner User Council (PUC) and APS Users Organization Steering Committee (APSUO SC) will be held on September 17, 2008, to hear preliminary reports from the 10 science teams working with the Renewal Steering Committee to prepare a draft white paper for a five-year renewal proposal to the DOE (see item 2). Each team has been charged with developing a scientific case in its field; the 10 science cases will be the basis for the white paper. PUC and APSUO SC members will be able to offer suggestions, as needed, for incorporation in the draft document to be discussed with the APS Scientific Advisory Committee and user community at the APS Renewal workshop to be held October 20–21, 2008. This joint session will be followed by separate afternoon meetings during which each organization will meet with APS senior management.
The receipt by the APS of $7.29 million in supplemental funding for the 2007 fiscal year provides welcome relief from the planned shortening of the 2008-3 running period, as well as eliminating the pressure to carry through with impending staff reductions.
Specifically, the additional funding enables the APS to offer 33 more shifts for users in 2008-3 (206 shifts instead of the projected 173). The 2008-3 run will include 122 shifts in 24 singlets, top-up mode; 36 shifts in hybrid fill, top-up; and 48 shifts of 324 singlets, non-top-up. Additionally, the 2008-2 run was extended by five days and now ends on Tuesday, August 12 (15.5 user shifts were restored to the schedule; all are 24 singlets, top-up mode).
It is generally conceded that Congress will authorize a continuing budget resolution until after the presidential election, which means a continuation of funding for the APS at the FY 2008 level until a new budget is passed. However, the supplemental funding should enable the APS to continue operations and staffing at current levels until that time.
Gabrielle Long has directed X-Ray Operations and Research (XOR) and the X-Ray Science Division (XSD) at the APS for five years. She joined the APS in 2003 as the first Associate Division Director for XOR and since 2006 has been the Director of the XSD. During her tenure, many talented young scientists and accomplished senior staff joined the APS as she shepherded the growth of XSD from operating 9 APS sectors to more than 16 sectors today. Her visionary scientific leadership has played a dominant role in our success and poised the APS for renewal and growth.
During this time, it is remarkable that Gabrielle also maintained a productive research career as a user of the APS; she has now decided that she would like to return to this activity full time beginning on August 1, 2008; she has agreed to remain in the XSD as a senior advisor.
In the interim period, while the APS carries out an international search for the next XSD Director, Mark Beno, Deputy Division Director of XSD, has agreed to serve as the interim division director, working closely with George Srajer, Associate Division Director for XSD's X-ray Operations and Research Group. Denny Mills (APS Deputy Director), Mark, and George will work closely with Murray Gibson, APS Director, in overseeing XSD through the vitally important renewal planning for APS.
The APS expresses strong gratitude to Gabrielle for her outstanding and distinguished service to APS and welcomes her insights during the transition.
--DOE Light Sources Coordinate Workshop Scheduling
Because synchrotron users often have ties to several facilities, conflicting events at those facilities can pose a problem. To help avoid such conflicts, the four light sources sponsored by DOE's Office of Basic Energy Sciences have begun exchanging information on scheduled conferences and workshops, especially those held on regular basis. For a snapshot of major meetings planned for 2008 at the ALS, APS, NSLS, and SSRL, see the table compiled by the light source user administrators in June. Another source of information on synchrotron-related meetings is the Conferences etc. link at lightsources.org.
This workshop at BioCARS (APS sector 14) will provide hands-on training in designing and conducting time-resolved experiments, Laue data processing, and time-resolved data analysis. Workshop participants will also have an opportunity to discuss with experts in the field application of the technique to their own scientific projects. Applicants may also bring a crystal for data collection. The application deadline is September 26; more information is available at the workshop web site.
A workshop on advanced crystallography using the ChemMatCARS beamline (APS 15-ID-B) will be held December 3-5, 2008. Recent upgrades permit structure determination and high-resolution charge density studies to a spatial resolution of 2.1 Å -1, and the workshop will focus on modulation structures and microcrystallography. Lectures and demonstrations will include an introduction to the new setup at 15-ID-B and use of various software packages for data analysis of challenging structures. Participants will be able to collect and analyze data on their own samples, with on-the-spot advice from experts for solving difficult structures. Both new and experienced users of the Advanced Photon Source are invited to attend.
Applications are due by October 1. Class size is limited to 18, and a registration fee of $50 will be charged. Full information is at the workshop web site. The workshop is co-sponsored by the Center for Advanced Radiation Sources of the University of Chicago , by ChemMatCARS, and by Bruker AXS.
