(Contact: alsum2002@lbl.gov)
General information, a preliminary program, meeting deadlines, and online registration for this year's ALS Users' Meeting, to be held at Berkeley Lab October 10 - 12, is available at the Users' Meeting Web site at http://www-als.lbl.gov/als/usermtg/. Register by October 1 to avoid late registration fees. Information about accommodations available to meeting participants in local hotels is available at http://www-als.lbl.gov/als/usermtg/accommodation.html.
Abstract Submission
The abstract submission deadline for poster presentations at the ALS Users' Meeting is Friday, September 27. See instructions for online submission at http://www-als.lbl.gov/als/usermtg/abstracts.html.
Workshops
This year, six focused workshops will follow the end of the formal Users' Meeting program on Friday, October 11, and Saturday, October 12. The workshop topics are as follows:
- Application of X-Ray Microdiffraction to Materials and Environmental Science
- Applications of Synchrotron Infrared Spectromicroscopy
- From Atoms to Aerosols: Opportunities for Chemical Physics at the ALS
- Scientific Opportunities in Polarization-Dependent X-Ray Spectroscopy and Microscopy
- Scientific Opportunities Using the Proposed meV Beamline at the ALS

Interested participants are encouraged to contact the workshop leaders (listed at http://www-als.lbl.gov/als/usermtg/workshops.html) for more detailed information about workshop agendas and speakers.
Award Nominations
The deadline for submitting nominations for the Halbach, Shirley, and Renner awards is Monday, September 30. An online nomination form can be found at http://www-als.lbl.gov/als/usermtg/awards/nominations.html. The awards will be presented at the ALS Users' Meeting dinner on Thursday, October 10.
2. UEC ELCTION: ONLINE RECOMMENDATIONS DUE SEPTEMBER 30
Recommendations for nominees to run in this year's Users' Executive Committee (UEC) election are being accepted online through September 30 at http://www-als.lbl.gov/als/uec/vote/. Note that these are not direct nominations; a UEC committee will consider these recommendations in drawing up a candidate list. Direct nominations from members of the ALS Users' Association may also be made by petition on an official nomination form, available for download (in PDF) at the above Web site. These require the signed endorsement of five Users' Association members and must be mailed or turned in at the upcoming Users' Meeting in October.
3. ALS TO PARTICIPATE IN BERKELEY LAB OPEN HOUSE ON OCTOBER 5
(Contact: EJMoxon@lbl.gov)
On Saturday, October 5, the ALS will again open its doors to the public as part of Berkeley Lab's Open House. This year the ALS will feature tours around the ring with stops at beamlines, as well as a walk under the facility's historic dome. On the patio, ALS and Physical Biosciences Division (PBD) staff members will be presenting several hands-on activities, including protein crystal growing, pipetting, solar power demonstrations and more, while inside, Steve Irick of the Experimental Systems Group will return with his popular "Visible Monochromator" activity. In addition, a series of half-hour talks by scientists and engineers will give visitors an overview of the diverse technical and scientific expertise required to run a successful research facility. Speakers and their topics include Carolyn Larabell of Life Sciences Division discussing her research with the x-ray microscope, retired ALS engineer Art Ritchie providing a unique overview of the building of the ALS, accelerator secrets from Christoph Steier of the Accelerator Physics Group, and PBD's James Holton talking about using the ALS to image proteins atom by atom.
In addition to the ALS, many other Berkeley Lab divisions are planning a busy day of activities and tours. Visitors can go behind the scenes and take a look at the 88-Inch Cyclotron (whose "gammasphere" detector was morphed into part of the ALS in the upcoming movie, "The Hulk"), view collections of exhibits from physics and nuclear science, or watch the action at a "robot corral" put together by the Engineering Division. Highlight lectures and talks, a family science tent, and a career fair are also included in the day's activities. More information about the Open House is available at http://www.lbl.gov/OpenHouse/.
4. 2001 ACTIVITY REPORT NOW AVAILABLE
(Contact:alsuser@lbl.gov)
Copies of the 2001 ALS Activity Report have arrived and are now being distributed to members of the ALS community. The report includes feature articles on two big news stories from 2001: the ALS contribution to the success of EUV lithography as the technology of choice for printing future generations of computer chips and the groundbreaking incorporation of three superbend magnets into the storage ring. In the science highlights section, accelerator physics has been added to the usual array of research categories, acknowledging the important scientific contributions made by ALS accelerator physicists. The facility section describes the progress made in the past year on numerous projects such as the Molecular Environmental Sciences beamline and PEEM3, as well as groundwork done on possible future projects such as a coherent far-infrared light source. The special events section chronicles a wide variety of ALS happenings, from the dedication of the AXSUN beamline to tours of the facility by award-winning student inventors. A CD containing a compendium of user abstracts is included inside the back cover.
If you do not receive a copy of the Activity Report within the next few weeks and would like to request one, send email to alsuser@lbl.gov with the words "Send Activity Report" in the subject line. Include your name and complete postal address in the body of the message. Copies will also be available at this year's Users' Meeting (see item 1 above).
