Acting Director's update:
Through a difficult transition

Janos KirzIt is hard to believe that it has only been a few months since my previous report in ALSNews. There is much that has happened, and if I had any hair left, there would be a lot more gray…

Based on the budget projections we were facing in April, I decided that we had to reduce the payroll by 7%, or 15 full-time employees, to balance the budget for the upcoming fiscal year. Going through the reduction-in-force (RIF) process was the most painful activity I have been involved in as an administrator—acting or not. We were fortunate in that we had significant attrition, and we also had several members of the ALS staff who volunteered to resign in order to save the jobs of others. Nevertheless, we could not avoid having to lay off staff and to return to the Engineering Division a number of people who played an important role in bringing the ALS to its current level of excellence. Throughout, ALS management aimed to keep our mission front and center: the ALS is here to support users in doing outstanding science in a safe environment.

With the RIF behind us, there is good news to report on several fronts:

The annual shutdown involved the installation of the first in-vacuum undulator (to serve the slicing source in straight section 6), the installation of higher-order dampers in one of the rf cavities, upgrades to the optics of several beamlines, and a variety of maintenance activities. It all went well, and the storage ring came back to user operations on schedule.

Preparations for the top-off upgrade are in full swing. Installation of the hardware for full-energy injection is planned for next year's shutdown. Implementation of top-off will proceed after that in stages over the better part of a year.

The PEEM-3 beamline (11.0.1) is being commissioned, and the first insertion-device beamline for the slicing source is close to being commissioned.

We just received the report on the Department of Energy's Basic Energy Sciences (BES) review of the ALS that took place in February. Each reviewer commented enthusiastically on the quality of the science and the productivity of the facility. In his cover letter, Pedro Montano, Director of the BES Scientific User Facilities Division, stated that the ALS "is in the forefront of soft X-ray and VUV source(s) in the United States" and that "Daniel Chemla is to be praised for transforming ALS into a world-class facility..." In his conclusion, Montano emphasized that "BES feels ALS serves as a model for how a user facility should operate." It would be hard to ask for a better report! Yet, there were three concerns expressed in the BES report:

  1. The general-user proposal review system is overloaded and needs to be overhauled. This is something we have been planning to do, and the new system will be announced shortly.
  2. Our beamline staff is spread too thin. We are aware of this problem and hope to alleviate it as the budget permits.
  3. While "recognizing the enormous contributions of Daniel Chemla," it is very important to begin a search for a full-time Division Director. In response to this concern, Berkeley Lab Director Chu went to see Daniel. Daniel agreed with the need expressed in the report. A search committee for a permanent director is being assembled.

Congressional action to date indicates that our fiscal year 2006 budget may be better than had been indicated by the President's budget proposal. Efforts by the Users' Executive Committee (UEC) and our users, as well as the users of other facilities, have been important in getting us to this point. Clearly, if we do receive a more adequate budget, we will be in a position to add beamline staff, as recommended. We will have to be careful, though, not to get into the situation where, in the following year (which is expected to be a difficult one), the budget cannot cover the payroll. If we are in a position to add staff, we will be looking for excellent candidates, especially women and members of other underrepresented groups. Please send applications and/or recommendations. I hope to have a good collection of files when the opportunity arises.

There are several important issues facing us. We need to secure funding for the Guest House and for the User Support Building and we need to implement the ALS Strategic Plan. I hope to give you a progress report on each of these at the time of the Users' Meeting, October 20–22. UEC representatives Simon Morton and Jinghua Guo have put together an exciting program, including 10 workshops. Please plan to attend!

Enol intermediates unexpectedly
found in flames

For those studying flame chemistry and the properties of combustion intermediates by means of molecular beam mass spectrometry, the addition of tunable vacuum ultraviolet (VUV) from a synchrotron to photoionize the beam for mass spectrometry makes for powerful technique capable of differentiating between isomers with the same molecular weight and composition. With the help of a unique experimental apparatus, an international team of American, Chinese, and German researchers has exploited this selectivity to identify chemical compounds known as enols as apparently ubiquitous intermediates in flames burning a variety of fuels. This surprising observation will require combustion modelers to revise their models to account for the presence of these compounds. Full story.

Fadley wins highly prestigious
Welch Award

Charles S. FadleyLongtime ALS user Charles S. Fadley has been awarded the highest honor bestowed by the American Vacuum Society (AVS), the Medard W. Welch Award. The citation reads: "For the development of novel techniques based on photoelectron spectroscopy and synchrotron radiation, and their application to the study of the atomic, electronic, and magnetic structure of surfaces and buried interfaces." The award confers $10,000, a gold medal, a certificate, and an honorary lectureship at a regular session of the society's International Symposium. The award was established in 1969 in honor of M.W. Welch, founder of the AVS, to recognize and encourage outstanding research in the fields of interest to the society.

Fadley received his Ph.D. in Chemical Physics from UC Berkeley in 1979 under the guidance of former Berkeley Lab Director David A. Shirley. He is currently a Distinguished Professor of Physics at UC Davis and a Senior Faculty Scientist in Berkeley Lab's Materials Sciences Division, holding one of three joint UC–Berkeley Lab ALS Professorship appointments. Recent projects undertaken by his research group include the use of standing x-ray waves to probe the properties of buried interfaces [Synchrotron Radiation News 17, 24 (2004)], the analysis of photoelectron diffraction patterns as holograms for depicting atomic or magnetic structure [J. Phys. Cond. Mat. 13, 10517 (2001)], and the spectroscopy of strongly correlated spintronic materials (Polaron Behavior of CMR Manganites). Fadley is the author or co-author of over 250 journal articles and over 30 review articles of book chapters, has served on numerous national and international scientific committees, and has mentored scores of students and young scientists over the course of his career. Congratulations to Chuck; the ALS is proud to count him among its many distinguished users!

Scientific Advisory Committee
convenes at ALS

Members of the ALS Scientific Advisory Committee (SAC) met at Berkeley Lab on Monday, July 11, to discuss a wide array of issues concerning the ALS. The committee has been consistent in providing ALS and Berkeley Lab management with sage advice on a range of critical issues, from the allocation of beamlines and approved programs to strategic planning, and from organizational and budgetary issues to broad policy matters. Berkeley Lab Director Steven Chu and Deputy Director Graham Fleming were on hand to welcome the attendees. Acting ALS Director Janos Kirz then brought the committee up to date on recent developments, reporting on, among other things, the BES review of the ALS that took place in February and on progress being made toward the transition to top-off operation. Ben Feinberg gave a short talk about the budget outlook and Gary Krebs briefed the members on plans for a Berkeley Lab Guest House.

Scientific Advisory Committee

Sunil Sinha, Sam Bader, Jennifer Doudna, Yves Idzerda, Neil Ashcroft, Phil Bucksbaum, John Spence, Steve Kevan, Tony Starace, Don Sparks, Pascal Elleaume, and Greg Denbeaux.

Zahid Hussain provided a brief report on a recent nanoscience workshop in Washington, and this served as an introduction to a report by Chris Jacobsen (Stony Brook University) on the workshop that he and Steve Kevan (University of Oregon) had organized to specify a new beamline dedicated to coherent diffraction imaging and scattering. Following the lunch and tour, Stephen Cramer (Physical Biosciences Division) described his approved program in biological spectroscopy, and SAC member Yves Idzerda then led a general discussion of other approved-program matters. Gary Krebs took the floor once more to discuss upcoming changes to the general-user proposal review process, and Neville Smith wrapped up the open-session agenda with a short talk about SAC terms and responsibilities. Current members of the advisory committee are listed online.
