I am glad to report that we just received $5.6M from the American Reinvestment and Recovery Act (ARRA) to support acquisition of new front ends and tandem/canted insertion devices (IDs) for three sectors (34-ID, 13-ID, and 16-ID) and new detectors for several other beamlines. Sectors 13 (GSECARS) and 16 (HP-CAT) were the winners of a competition held by the APS Scientific Advisory Committee several years ago to propose upgraded x-ray sources, and in both cases these are highly leveraged by external funds for beamline optics and instrumentation. The sector 34 investment will help to strengthen the Bragg coherent diffraction imaging and the polychromatic micro/nano diffraction programs that currently share a single ID. ARRA investments will increase the performance and capacity of strategic scientific programs. We plan to use some of the ARRA funds to secure additional staff to support detector operations and engineering design.
We are fortunate this year to have received adequate funds from the Department of Energy (DOE) to support full operations. We are also thankful that the President's FY2010 budget includes a needed operating budget increase for APS that would bring us to the level needed to properly execute our mission including the operation of the majority of APS beamlines (which was not envisaged when the original operating budget for APS was set). The implementation of this budget increase is in the hands of the US Congress, and it is just a small a part of the proposed doubling of the physical sciences budgets at the DOE, the National Science Foundation, and other science agencies that have been strongly supported by the administration and many in congress. However, in these tight fiscal times where tough choices must be made to control deficits, it behooves the science community to continually emphasize the strategic importance of science and technology to the future security of the United States .
The DOE Office of Basic Energy Sciences asked us to submit a proposal for the Critical Decision 0 (CD-0) for the APS renewal project. The proposal was submitted on May 31, 2009, and is currently being reviewed at the DOE. [Note: While the proposal is being reviewed, we are not distributing it widely. However, if you want a copy please e-mail Rick Fenner who can provide a printed copy or talk to an APS staff member.] The proposal describes a vision for the renewed APS that will deliver order-of-magnitude improvements in performance for the majority of beamlines; allow us to address compelling problems in sustainable energy, human health, and economic competitiveness; and help the United States take a leadership role in the development of hard x-ray science in the next decade. The proposal expanded on the extensive network of user workshops that culminated with the Strategic Renewal Planning Workshop last October. If we are granted the CD-0 decision this summer, we will move ahead aggressively in FY2010 to develop a Conceptual Design Report and will engage the user community in the detailed decision making process for the components of the renewal project. There is still time to engage if you have not done so already. Early this fall (October 8-9, 2009), we are planning a workshop to be held in conjunction with our Scientific Advisory Committee meeting that will be an important next milestone in the renewal planning process. Please check our Renewal web page for the latest details.
Launched in early 2008, the 11-BM beamline offers mail-in users rapid access to the highest resolution synchrotron powder diffraction instrument in North America . The beamline uses a unique APS-designed 12-crystal multi-analyzer detector to achieve high throughput without compromising performance. We are pleased to announce that 11-BM will now also be accepting user proposals for on-site experiments starting with the 2009-3 run cycle.
On-site users will have the option to mount samples either on a standard goniometer head or make use of the unique automated robotic sample changer used for mail-in data collection at 11-BM. Data can be collected at sample temperatures between 80 K and 500 K using a cryostream blower. Plans are underway to expand this temperature range in the near future as well as to offer additional sample environments such as in situ reaction cells. The current available beamline energy range is 15-35 KeV.
New users are encouraged to consider the 11-BM rapid access mail-in service, which allows users to go from a short proposal to data analysis in less than one month. Proposals are submitted through the Advanced Photon Source General User Program. The rapid access mail-in service is appropriate for users with a limited number of samples and is a free service for all non-proprietary users. Users requiring more than one shift (8 hours) of data collection may use the mail-in service but not rapid access. Mail-in data collection is performed at a fixed energy (~ 30 KeV) and users are offered standard scans at a select number of temperatures.
We intend to increase the range of measurement protocols available through the mail-in interface. To gauge user interest, mail-in users are welcomed to communicate with beamline staff (11-BM@aps.anl.gov) to request that samples be measured at a wider range of temperatures than the ambient and 100 K options currently available in the web interface. Different scan speeds or ranges are also possible, as well as protocols for samples that are quickly degraded in the beam.More information about 11-BM and the rapid access mail-in program can be found at http://11bm.xray.aps.anl.gov.
Interesting topics in research conducted at the APS can be found on the APS home page:
- Using High-Pressure “Alchemy” to Create Nonexpanding Metals

- A “Colossal” Magnetic Effect under Pressure
GSECARS will hold a workshop September 23-25, 2009, on the subject of on-line Brillouin spectroscopy combined with high-resolution x-ray diffraction (XRD). The main advantage of the unique combination of Brillouin spectroscopy with high-resolution XRD techniques is the ability to perform simultaneous measurements of velocities, elastic moduli, and volume/density independent of any pressure standard. With this system, located in the 13-BM-D station (GSECARS, APS), it is now possible to study materials in situ at high pressure-temperature conditions that provide information essential for interpreting seismic observations and constraining models of the composition and evolution of the Earth.
The workshop will include:
- fundamental aspects of Brillouin scattering
- experimental challenges of Brillouin scattering and XRD at high pressures and temperatures
- plenary lectures
- contributed presentations
- hands-on demonstrations
- software for data collection and analysis
A workshop is being offered July 29-31, 2009, at the Stanford Linear Accelerator Center to discuss near-term options for enhanced performance (wavelength reach, polarization, pulse duration, etc.) as well as the science drivers for the long-term development of the Linac Coherent Light Source (LCLS) for hard x-ray based science. On April 14, 2009, the LCLS had a dramatic start up at its shortest wavelength (1.5 Å) reaching saturation with 1.1 mJ per pulse energy (see P. Emma's paper here). This is the baseline performance, but there is room for advancement.Please visit the meeting web site to register; there is no registration fee and the cost of meals will be collected on site. The meeting format will provide a forum for significant discussion among participants. This workshop is an exciting opportunity for the scientific community to interact with the LCLS team and the free electron laser physicists to investigate future directions for the facility that could expand the current capabilities and take the LCLS in new scientific directions.

The annual meeting of the National User Facility Organization (NUFO), held at Argonne National Laboratory on June 10-12, 2009, was hosted by all of Argonne 's user facilities, including the APS. Day one of the meeting focused on users and the role they play in promoting science at the national and international levels. Dr. Harriet Kung (Director of Office of Basic Energy Sciences, DOE) addressed the role that user facilities will play in the country's energy challenges. Dr. Amy Flatten (Director of International Affairs, American Physical Society) followed with a summary description of the issues affecting visa processing and foreign national entry into the United States since 9/11. She encouraged foreign nationals experiencing difficulty obtaining a visa to enter the United States to complete a Visa Questionnaire form, which is available through the Board of International Scientific Organizations at the following site: http://sites.nationalacademies.org/pga/biso/visas/PGA_048017.
The afternoon focused on how NUFO fits into the national science agenda, the differences in expectations of users and user facilities (and how they can be resolved), the role of user facilities in supporting academic research and workforce development, and the specific needs of U.S. users of international user facilities.
Day two of the meeting was devoted to industrial research. The day began with a presentation from Mike Lubell (American Physical Society), whose talk covered fifteen years of science policy lessons--the primary one being that the voices of industry and medicine talk most loudly in Washington. John Palafoutas (Task Force for the Future of American Innovation) followed by describing the primary mission of the Task Force, which is advocacy for science funding. NUFO belongs to the Task Force, as do many industrial companies. The remainder of the workshop focused on industrial stories from small and large businesses and outlined what works well at our user facilities and where improvements can be made. Representatives from GE, Eli Lilly, Dupont, Creatv MicroTech, Inc., SEMATECH, and AEgis Technologies, as well as members from national laboratories provided their perspectives. The session ended with three breakout group discussions on outreach to industry, interactions before arrival, and interactions at the facilities. Summaries from these sessions will be included as appendixes to a brief report to the DOE on the workshop as a whole. This report is currently being prepared.
The meeting ended on Day 3 with a robust discussion on administrative issues, primarily those related to the foreign visits and assignments program and visas. Results from benchmarking studies were presented, and a consensus was reached on continuation of the benchmarking efforts
Presentations from the meeting are now available on the meeting Website: http://www.aps.anl.gov/Users/NUFO/2009_Meeting/Presentations/index.htm.The next annual meeting will take place at Brookhaven National Laboratory in 2010.
