1. READERS TALK BACK: ALSNEWS SURVEY 2002
(Contact: alsnews@lbl.gov)

ALSNews reaches an important milestone today with the publication of its 200th issue. In its debut on November 1, 1994, ALSNews reported on the first images produced at Beamline 6.1.2 (red blood cells infected with the malaria parasite), the commencement of LIGA work at Beamline 10.3.2, and a summary of the 1994 Users' Meeting, where topics of discussion included "future scientific opportunities at the ALS such as protein crystallography and polymer microscopy," and "the possibility of building an infrared beamline at the ALS." The ALS has come a long way since then, and we hope that ALSNews has evolved as well to meet the needs of our ever-growing and increasingly diverse audience. After seven and a half years, this newsletter's distribution has reflected the growth in the ALS user community, increasing from a few hundred subscribers initially to nearly 2000 from over 20 countries today. We always appreciate it when our readers write with comments or suggestions. At this milestone, however, we would like to make a more systematic effort to find out what your needs are so that we can serve you more effectively. A short online survey can be found at http://www-als.lbl.gov/als/als_news/surveys/2002/. It should take only a few minutes to complete and will provide us with valuable feedback on how best to serve the ALS community.

2. PROTEIN CRYSTALLOGRAPHY PROPOSALS DUE JUNE 15
(Contact: pxproposals@lbl.gov)

Saturday, June 15, 2002, is the next deadline for independent investigator protein crystallography proposals for beamtime during the month of August 2002.

Scientists wishing to submit a proposal will need to fill out a Protein Crystallography Proposal form at http://alsusweb.lbl.gov/. For questions regarding the proposal process, please contact Jeremy Coyne at pxproposals@lbl.gov or 510-486-4518.

3. SUMMER SCHOOL PHYSICAL SCIENCES COURSE STILL OPEN

There's still room in the 2002 Stanford-Berkeley Synchrotron Summer School physical sciences course. This year the summer school will be held at Stanford University July 7-13. The program will provide a comprehensive overview of the synchrotron radiation process, requisite technologies, and a broad range of scientific applications. It will cover both fundamentals of extreme ultraviolet, soft x-ray, and hard x-ray synchrotron radiation and their use in spectroscopy and diffraction. Science applications will be given both in physics, chemistry, and materials science. Lectures will be presented by scientists from the sponsoring organizations and affiliated user communities. The attendees will participate in experiments on different beamlines at the ALS and make visits inside the storage ring at the Stanford Synchrotron Radiation Laboratory (SSRL). For more information, see the web page at http://smb.slac.stanford.edu/SR-School/ps2002.html.

4. ALS AWARDS AND HONORS

The ALS is pleased to acknowledge those in its orbit whose achievements have been recognized through awards and honors. Congratulations on a job well done!

Hendrik Ohldag, graduate-student member of the Beamline 7.3.1.1 (PEEM2) participating research team, received a Materials Research Society (MRS) Gold Award at the society's Spring 2002 meeting in San Francisco. The MRS Graduate Student Awards are highly competitive and are intended to honor and encourage graduate students whose academic achievements and current materials research show a high order of excellence and distinction. Finalists for the awards participate in a special student-presentation judging session at one of the society's meetings. Criteria for selection include thoroughness of the work; originality and independence of the contribution; depth of understanding of the topic, methodologies, and context; and finally, promise for future achievement. Hendrik is affiliated with the Stanford Synchrotron Radiation Laboratory, the Advanced Light Source, and the University of Duesseldorf, Germany. The work described in his winning paper, "Understanding Magnetic Coupling at Antiferromagnetic/Ferromagnetic Interfaces - A Dichroism Spectromicroscopy Study," was also the subject of his award-winning student poster at the 2001 ALS Users' Meeting.

6. OPERATIONS UPDATE
(Contact: Lampo@lbl.gov)

For the user runs of May 21 - 26 and May 30 - June 2, the beam reliability (time delivered/time scheduled) was 95%. Of the scheduled beam, 91% was delivered to completion without interruption. There were no significant outages.

Long-term and weekly operations schedules are available on the Web (http://www-als.lbl.gov/als/accelinfo.html). Requests for special operations use of the "scrubbing" shift should be sent to Bruce Samuelson (BCSamuelson@lbl.gov, x4738) by 1:00 p.m. Friday. The Accelerator Status Hotline at (510) 486-6766 (ext. 6766 from Lab phones) features a recorded message giving up-to-date information on the operational status of the accelerator.
