Workshops. The summer is ramping up with a series of exciting workshops on the “Future Scientific Directions for the APS,” culminating in a strategic planning meeting September 2nd and 3rd (read more in item 4). We hope that the momentum generated by this study will lead to development of new and expanded user communities and to strong proposals for the remaining four insertion device sectors at APS.

Industrial and proprietary research. At the Users Meeting, APS staff met with major industrial users of the APS for a frank discussion of issues concerning APS policies for proprietary research and for evaluation of nonproprietary industrial research. At the outset of the meeting, the APS proposed several policy and procedural changes in this area. Based on valuable discussions about the practicality of the revisions, we will make further changes and release a revised set of policies and procedures for further review by the group. We hope to implement new policies and procedures by the end of the calendar year. As with all new APS policies and procedures, comment is orchestrated by the Partner User Council (PUC, formerly the Research Directorate). If you are interested in this particular issue, and would like to be involved in the review process but have not been so far, please contact you PUC representative (see list at http://www.aps.anl.gov/user/committees/puc/puc_list.htm), or the PUC chair, Jim Viccaro (viccaro@cars.uchicago.edu).

Operating models for synchrotron facilities. An Inter-Agency Working Group on synchrotron radiation is being convened this summer to evaluate operating models for synchrotron facilities and to make recommendations on appropriate staffing levels and partnering models for existing and future facilities. I believe that this is an important opportunity to articulate the changes in operating model for the APS, and to emphasize the importance of increased operational support and of attracting outside partner users to the APS. I will be communicating closely with this group and with APS Users Organization and Partner User groups as the study progresses. The chair of the study is Patrick Gallagher, Director of the NIST Center for Neutron Research (patrick.gallagher@nist.gov).

I hope that you have a wonderful summer, and that your future light-source experimental plans include the APS!

2. Research Highlight: Visualizing Ferroelectric Memory As It Fades
(Contact: Paul Evans, evans@engr.wisc.edu)

A team of APS users from the University of Wisconsin , Bell Laboratories, and the University of Michigan has combined x-ray microdiffraction with in situ electrical measurements to study micron-scale details of polarization fatigue in ferroelectric oxides.

These parallel measurements revealed a qualitative difference in the structural changes accompanying fatigue, depending on whether a high or low electrical field is used to switch the polarization. The studies were conducted at beamline 7-ID (MHATT/XOR) with 10 keV x-rays focused to a 0.8-µm spot.

The phenomenon of polarization fatigue is a subject of intense study because it affects the lifetime of nonvolatile memory devices in which data is stored even when the power is turned off. Ferroelectrics retain their polarization states without consuming electrical power. However, after a number of cycles, the switchable polarization begins to taper off, rendering the device unusable.

3. Construction Season in Chicago : Work Begins on CNM and LOM 437
(Contact: Rick Janik, rej@aps.anl.gov)

Two major construction projects will begin at the Advanced Photon Source (APS) this summer: the Center for Nanoscale Materials (CNM) and Laboratory Office Module (LOM) 437.

The Center for Nanoscale Materials is one of five nanoscale science research centers being funded by the U.S. Department of Energy. Its mission includes supporting basic research and the development of advanced instrumentation that will help generate new scientific insights and create new materials with novel properties based on nanoscience and nanotechnology research.

The CNM will be a two-story, 85,000-square-foot structure adjoining the west side of the APS facility. It will contain clean rooms, specialized research laboratories, offices, and meeting spaces to accommodate users, scientific and technical staff, and administrative support.

The building was designed by M+W Zander of Chicago and will be built by Walsh Construction. The construction of the buildings is being managed by an Argonne National Laboratory project team with support from the Jacobs Engineering Group. The total cost of the CNM project will be $72 million, of which $36 million will be provided by the State of Illinois for conventional facilities construction.

Project construction will begin the first week of July 2004, and the CNM is scheduled to be completed and occupied by April 2006. During this period, a portion of Kearney Road will be closed and fenced off between Rock Road and Bluff Road (see map). Periodically, Rock Road (the road immediately north of Building 401) will be closed while underground utilities are located adjacent to and across the road.

Construction of LOM 437, the last of the eight Laboratory Office Modules originally envisioned, will be built during the same time frame as the CNM. It will be located between the CNM and LOM 438. The APS has received funding to begin construction of this last LOM in conjunction with the CNM so that the major disruptions associated with construction (especially vibrations from earthmoving, concrete work, etc.) will be completed before the CNM begins commissioning and using vibration-sensitive equipment.

LOM 437 (22,000 square feet) will include all the design enhancements included in the most recently constructed LOMs, such as provisions for storage rooms between pentagons and an expanded floor coordinator's office. The building occupants will share a parking lot with the CNM. The engineering design will be completed by the APS Conventional Facilities Group.

4. Strategic Summer: Summary of July and August Workshops
(Inquiries: Bonnie Meyer, bsm@aps.anl.gov)

The following is a précis of four of the eight workshops planned to define the future science directions forthe APS. A registration form is available at the web sites indicated below.

Emerging Areas in Biological Crystallography
July 26-28, 2004, at APS
Co-Chairs: Wayne Hendrickson (Columbia University), John Helliwell (University of Manchester)

Developments in synchrotron radiation sources over the past 20 years have revolutionized methods for determining the structure of proteins. Work in recent years has focused on issues of efficient and effective use of these sources. This workshop will look beyond these issues toward future challenges of this field of research, concentrating in the following areas (see web site for details on each):

Workshop on Frontier Science Using Soft X-Rays at the APS
August 5-6, 2004, APS, Argonne, Illinois
Co-chairs: Juan-Carlos Campuzano (ANL/ Material Science Division) and Richard Rosenberg (APS)

This workshop will focus on emerging opportunities for the use of linearly and circularly polarized synchrotron x-rays in the range 400-2500 eV. Some opportunities to be discussed are angle-resolved photoemission with 10-15 meV resolution of soft x-rays, probes of microscopic magnetic behavior, and structure studies on length scales of nanometers. In addition to applications in condensed matter physics and materials science (such as oxide superconductors and highly correlated complex materials), many new biological applications of soft x-rays are also emerging.

Workshop on Science with High-Energy X-rays
August 9-10, 2004, APS, Argonne , Illinois
Chair: Dean Haeffner (APS)

This workshop will explore the scientific opportunities made possible by the considerable capabilities available at the APS for working with high-energy x-rays. Among the topics that will be covered are

Workshop on Membrane Science
August 17-18, 2004, APS, Argonne , IllinoisCo-chairs: Millicent Firestone (ANL/Chemistry Division), Tom Irving (Illinois Institute of Technology), Jin Wang (APS), Randall Winans (ANL/Chemistry Division)

The focus of this workshop will be techniques for understanding chemical ordering, pattern formation, kinetics, and dynamics in organic, inorganic, and bio-membrane structures. Further questions are the physical interactions between bio-membranes and supramolecules, their dynamics under stimuli, and the formation and structure of ion channels in such membranes. Workshop participants from many areas of membrane science will identify research frontiers where collaborative activities using synchrotron radiation techniques can be rewarding.

Next Issue : The remaining four workshops (to be held at the Abbey, Lake Geneva , Wisconsin from August 30 to September 1) will be summarized in the next issue. These will be followed by Strategic Planning Meeting of the APS at the same venue on September 2-3, 2004.

5. The LCLS Experimental Program: Call for Letters of Intent
(Contact: Jerry Hastings, lcls-useradmin@slac.stanford.edu)

The Stanford Synchrotron Radiation Laboratory (SSRL) is seeking to establish partnerships with selected teams of scientists that will collaborate with the Linac Coherent Light Source (LCLS) on instrument design and the experimental program. The LCLS, expected to become operational in 2008, will be the first free electron laser (FEL) to produce hard x-rays spanning the wavelength range 1.5-15 Å. As the first step in forming these partnerships, the LCLS Scientific Advisory Committee (SAC), together with SSRL and LCLS management, has issued a broad call for letters of intent (LOI) from prospective LCLS research teams. While the deadline for the initial round of consideration has recently passed, expressions of interest are still very welcome. Details of the call for LOIs, timetable, and technical issues are at the sites listed below.
