APS Renewal Planning for 2009

The Renewal program for the APS promises to be a unique opportunity to upgrade the facility and address user needs for the next decade. We expect that the Renewal could provide ~$400M to enable a scientific vision of our facility involving new and upgraded beamlines, improved detectors and software, and significant accelerator improvements. We are hopeful that the project may start in 2010, so it is important to keep momentum in developing our proposal. The following outlines renewal planning activities for 2009 and explains the mechanisms for user input.

From the beginning, the APS Scientific Advisory Committee (SAC) has provided advice on the selection of beamlines at the APS. We use a formal process beginning with letters of intent, followed by invited scientific proposals and SAC review before approving new beamline construction. The existing process will continue and be folded into the Renewal. Although we already have many relevant proposals in hand, users should ensure that any substantially new ideas are laid on the table soon to be included in the Renewal. We hope that all users of the APS, including independent CATs, will make certain that their future vision is part of the Renewal planning and submit letters of intent as appropriate. Consult our Renewal web page, which lists all the proposals we have received so far.

For several years we have been stimulating proposals for new beamlines; currently, we have seven in various stages of review. We also invited and received dozens of proposals from the community last summer for beamline, accelerator, and infrastructure improvements. In late 2008 the community developed a compelling scientific vision of the impact that the renewed APS could have on society. As we further develop this scientific plan, we must identify the specific upgrades that will enable our scientific vision.

We had extensive discussions with the SAC at their recent January 2009 meeting about the path forward (see the links to SAC presentations by Denis Keane, Dennis Mills, and Paul Fuoss). SAC tasked APS management with the next step of taking the information provided by the user community so far and putting together a vision for what we see the APS providing to users in 2017 once the Renewal program is complete. We will identify new beamlines, new accelerator capabilities, enabling tools, and increased capacity in strategic areas. APS management will work closely with the Renewal Coordinating committee as we develop this strawman proposal for the key Renewal elements. The proposal will be discussed with the community at the May 2009 APS Users Meeting. During the summer following the Users meeting there will be much opportunity for user response to the strawman proposal. This feedback will help us develop a stronger proposal to be examined by the SAC at a special meeting planned for October 8-9, 2009.

We expect that the SAC will continue to advise on the Renewal proposal development and conceptual design and to oversee the progress on the project, especially where scientific choices are involved. Later this year we expect to create a Facility Advisory Committee that will advise the SAC on the technical components during the proposal stage and oversee technical progress during the project.

1. Life Sciences CAT Coaxes Four Beams from One Port, Offers New Membership Mode

The Life Sciences (LS) CAT occupies sector 21, where three of four parallel ID beamlines are currently operational for protein crystallography. General users are accepted at all operational stations, and new institutions are invited to join the Collaborative Access Team as associate members.

While a few sectors have a C or D station, Sector 21 delves much further into the alphabet to identify its stations--all the way to G! That's because stations A, B, and C are in essence an x-ray switch yard that directs beam from two canted undulators to the other four stations, D through G. The D station has its own undulator while the others share an undulator using two side-bounce monochromators and one large offset monochromator tuned near the selenium edge.

The beamlines are basically quadruplets designed to be nearly identical in order to gain economies of scale: All have an MD-2 diffractometer with state-of-the-art features such as on-axis sample viewing with precision zoom, automatic sample alignment, omega/kappa/phi motions, and a tuned piezoelectric fast shutter; and all will have the same robotic sample changer. (The robots are already in place on the D, F, and G stations.)

Aside from cost savings, the quadruplet approach also cuts the learning curve for users and the staff effort required to maintain the facility. “The idea was to keep the user interaction as simple as possible,” says LS-CAT sector manager Keith Brister.

This approach to beamline development meant the LS-CAT operation came on-line exceptionally fast. “For example, in May 2007 there was nothing in the side-bounce stations [F and G], ” Brister says, “but in August 2007 we had scheduled users on both.” The D station took its first x-rays in the fall of 2006, and the first user work was done a few months later in December. This station got a nine-month head start over the others because a Mar DTB diffractometer was used initially while the permanent equipment was on order. “Stations D, F, and G are currently open to users and the E station will be the last one to come on line,” Brister says.

LS-CAT was founded in 2003 with seed money from the State of Michigan through the Michigan Core Technology Alliance; it currently has eight member institutions. To serve the needs of other users, who need a relatively small--but predictable--amount of time but for whom a full membership is not practical, LS-CAT is starting an Associate CAT Member program. This program allows institutions to enjoy the benefits of CAT membership but with a smaller commitment.

General users interested in rapid access time can subscribe to a weekly Rapid Access Alert via the LS-CAT web site that shows the rapid access schedule three weeks out. This schedule is also available on the LS-CAT fact sheets for the LS-CAT beamlines in the APS beamline directory. The CAT is also considering providing remote access and mail-in service sometime in the next year, contingent on the installation of the robots. This mode should be advantageous to users who have only a few crystals at a time. “It's basically a time-share in a dewar!” jokes Brister. “We want users to feel like they can always have beam time right away.”

For additional information regarding these opportunities at LS-CAT, contact Keith Brister at k-brister@northwestern.edu .

3. White Paper on “Science and Technology of Future Light Sources” Online

"Science and Technology of Future Light Sources," a document prepared as a briefing for the Obama administration about the exciting promise of fourth-generation light sources, is available online as a PDF file.

The document is a collaborative effort by scientists from Argonne National Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and SLAC National Accelerator Laboratory, including faculty from the University of California-Berkeley and Stanford University .

While the immediate focus at the APS is on the proposed Renewal program, this white paper addresses the possibilities for a longer-term goal in the development of a fourth-generation hard x-ray source.

USER MATTERS

4. How Are We Doing?

Each year, APS users are asked to let us know their answers to this question when the APS sends out its annual user satisfaction survey. Included are questions asked by every DOE/BES user facility, as well as questions specific to the APS. Traditionally between 400 and 500 users chime in--at least 75% of whom are General Users, with approximately equal responses from the life and materials science communities. Since FY 2003, the answer to the question, “Which would be most important to your research: increased hours, increased availability, or increased reliability?” has changed gradually from increased reliability to increased hours. This trend was strongly reinforced this year by the number of comments related to providing more beam time to users. Overall, the strong majority of users are either very satisfied or satisfied with the fraction of the year we operate, our schedule and service, and the support provided by facility and beamline staff. More details are available in a presentation given recently by APS Deputy Director Dennis Mills to our resident user community.

5. Management Changes in the APS X-Ray Science Division

To simplify the organizational structure and provide enhanced efficiency for APS-operated beamlines, the X-ray Operations and Research Section of the X-ray Science Division is being reorganized in a multi-phase process. In the first phase, which becomes effective on March 15, 2009, three new XOR groups will be formed. These groups, the beamlines they are responsible for, and their new group leaders are as follows:

  • Spectroscopy (20-ID, 20-BM, and 9-BM), group leader: Steve Heald
  • Structural Science (11-ID), group leader: Peter Chupas
  • Surface Scattering and Nanodiffraction (33-BM, 33-ID, and 34-ID-E), group leader: Paul Zschack

The former Chemistry, Polymer, and Environmental Group will operate Sector 12 and will be renamed the Chemical and Materials Science Group. Randy Winans will lead this group. The Materials Characterization Group will continue to operate Sector 1 and beamline 11-BM, with Brian Toby as the group leader. Finally, Thomas Gog will continue to lead the Inelastic X-ray and Nuclear Resonant Scattering Group now operating sectors 3 and 30 and beamline 9-ID.

6. General and Partner User Proposal Deadlines

The submission deadline for new General and Partner User proposals, as well as beam time requests against active proposals, for the 2009-2 user run is March 6, 2009. Please note: Until new staff members are hired, general user beam time will be somewhat limited on the following beamlines: 9-BM, 12-BM, 33-BM, and 34-ID. To maximize your chances of obtaining General User beamline during the 2009-2 run, be sure to check the “Any appropriate beamline” option on your beam time request form. In addition, 1-BM will again be accepting General User proposals for 70% of the available GUP beam time only for powder diffraction experiments with a large area detector (Mar 345) and a fixed nominal energy of 20 keV. For the remaining 30% of time, this beamline will not be operated.

7. User Agreements

To make it easier for industrial and university staff members to conduct research at DOE national user facilities, the DOE has developed new standard (master) user agreements for non-proprietary and proprietary research. These master agreements, which deal with intellectual property, liability, and financial issues, are designed to cover all individuals from a single institution at all user facilities at a specific national laboratory. Although the agreements are essentially the same for each national lab, the DOE has permitted some minor flexibility, subject to approval by the local DOE Site Office. The master non-proprietary agreement for Argonne National Laboratory has now been approved. All newly executed agreements will be master agreements; very shortly Argonne will begin replacing the current agreements with the new master forms. If you have questions, contact Susan Strasser (strasser@aps.anl.gov).

8. General User Program Advisory Committee Established

To assist the APS in responding appropriately to user suggestions regarding our General User Program, a standing advisory committee reporting to Deputy Associate Laboratory Director Dennis Mills has been established. Issues about the program itself, suggestions for improvements, and comments should be submitted to this committee in care of Meg Vigliocco-Hagen (meg@aps.anl.gov) or to any of the committee members. The following individuals have agreed to serve: Bruce Bunker (Partner User Council representative), Keith Brister (Life Science Council representative), Jonathan Lang (APS X-ray Operations and Research representative), Robert Leheny (General User and APS Users Organization representative), Steve Sutton (national user facilities representative), Jon Tischler (Beam Time Allocation Committee representative), Paul Zschack (co-chair of the 2002 General User Program Committee), and Susan Strasser, ex-officio (Manager, APS User Programs). Current issues under consideration by this committee include GUP proposal project status, proposal score aging, accounting for time when users cancel at the last minute, and changes to the macromolecular crystallography submission process and schedules.

9. Search to Begin for the Next Accelerator Systems Division Director

Current ASD Director Efim Gluskin has spent 10 years in senior management at the Advanced Photon Source (APS), first as Division Director of the X-Ray Facilities Division and since 2006 as the Director of the Accelerator Systems Division (ASD). Before that he led the design and construction of the world-recognized insertion device systems at the APS. He has been a technical leader in the development of free-electron lasers (FELs), and has played a major role in overseeing Argonne 's role in the Linac Coherent Light Source (LCLS) project. Efim's unique combination of leadership and technical excellence are an asset to Argonne.

However, seeking new challenges, for some time Efim has been expressing his desire to return to research and relinquish senior management responsibilities. APS management has finally agreed to begin an international search for the next Division Director of ASD. Efim has kindly agreed to remain in his position until a successor has been appointed.

The following committee has been appointed to conduct the search:

  • Emilio Bunel (CSE- ANL)
  • John Galayda (SLAC)
  • Rod Gerig, Chair (PSC-ANL)
  • Steve Holmes (Fermilab)
  • Kwang-Je Kim (ASD-ANL)
  • Liz Moog (ASD-ANL)
  • Jerry Nolen (PHY-ANL)
  • Vadim Sajaev (ASD-ANL)
  • Maury Tigner (Cornell University)
  • John Quintana (AES-ANL)
