1. Message from Murray: Cross-Cut Review, COM-CAT/Sector 32 Update

We have very exciting number to report: in 2005, a total of 3217 users came to the APS--up 15% from 2004 and double the figure for 2001. This growth in the APS user base reflects the hard work of our employees who support the reliable operation of the facility and provide user support in myriad ways. Our challenge is to sustain this growth in difficult budget times. In a recent study by the Office of Basic Energy Sciences, reported by Pat Dehmer at the SSRL users meeting (link below), it was recognized that the APS currently has only about 60% of the optimal staffing we need for operation of all our operating beamlines. In addition, we have several unbuilt beamlines and many beamlines in need of renovation. A recent DOE-BES review of the APS, while overwhelmingly positive, identified our compelling needs for increased staffing and capital investment. I will share details of this review with you in the near future. We also have plans for innovative machine enhancements, such as a picosecond pulse capability, that will make possible entirely new kinds of science at the APS. We are very appreciative of the support of our users in advocating for the APS, and of DOE-BES for their sustained support. We will continue to work with our sponsors at DOE-BES to deal as best we can with challenging times which face the general science complex today, and to make the strongest case for additional investment in the APS.

2. Date Correction: Cross Cut Review on January 25

The Cross Cut Review of Polymer Science will be held Wednesday, January 25, 2005 (not the 26th, as reported in the last issue). The review is public and will be held in the APS Auditorium. Currently, the agenda includes presentations by Wes Burghardt, Northwestern U.; Timothy Lodge, U. of Minnesota; Sunil Sinha, U. of California-San Diego; Dale Schaefer, U. of Cincinnati; Jin Wang, Advanced Photon Source; and Roger Leach, DuPont. The final agenda will be posted at the page listed below.

3. Science Highlight: "Demixing" of Metallic Liquids Seen for First Time

Scientists have seen for the first time metal atoms near the surface of a liquid alloy arrange themselves in alternating layers one atom thick. This "surface demixing" was predicted in 1950, but it eluded experimentalists for more than 50 years. The collaborators, led by physicists from Harvard University, used beamline 15-ID (ChemMatCARS) to look at how atoms of bismuth and tin behave when they form a liquid alloy. In the bulk material, the two elemental liquids form a perfectly miscible solution, but near the surface they separate into atomic layers with alternating compositions. The research has implications for nanomaterials and could lead to such applications as improved lead-free solder for electronics.

4. SRI-2005 Detector Workshop Moved to APS

The satellite workshop on detectors scheduled for SRI-2005 at the Center for Advanced Microstructures & Devices in Baton Rouge, Louisiana, has been rescheduled to December 8 and 9, 2005, and relocated to the Advanced Photon Source at Argonne National Laboratory in Illinois.

Registration: http://www.aps.anl.gov/News/Conferences/2005/Synchrotron_Radiation_Instrumentation/index.htm


5. Shop and Machine Tool Users: Reauthorization Required by February 1, 2006

The policy and procedure for access to APS user machine shops has been revised. Users currently allowed access to user shops and machine tools must arrange to be reauthorized by February 1, 2006, to retain their privileges. The authorization is valid for two years.

The new authorization procedure includes written and hands-on certification tests administered by an outside contractor. The tests require advance scheduling, so we encourage interested users to go through the new process at their earliest convenience. Contact the shop coordinator for your sector to schedule reauthorization. Study guides for the tests are at http://www.aps.anl.gov/Safety_and_Training/Safety_Guides/, under "User Shop Study Guides."

The revised policy and procedure covers all user-managed machine tools, whether or not they are located in the lab-office module (LOM) user shops.

Contact for reauthorization: Shop coordinator for your sector

6. Pete Jemian Heads Beamline Controls and Data Acquisition Group

In October, the APS was very pleased to welcome Dr. Pete R. Jemian as the group leader for the Beamline Controls and Data Acquisition Group. Dr. Jemian received his Ph.D. in materials science and engineering from Northwestern University . Since 1994, Dr. Jemian was the USAXS instrument scientist at UNICAT and was responsible for the UNICAT control system. Pete is located in Building 401, Rm. B1168; you can reach him at 630-252-3189 or jemian@anl.gov. The APS is grateful to former group leader John Maclean for serving in a dual role while a new group leader was found.

7. Nominations Packages Due Feb. 15 for 2006 APSUO Franklin Award

Nominations are now being accepted for the 2006 APSUO Rosalind Franklin Young Investigator Award. Prospective nominators are already lining up with candidates! The award will be presented on May 3, 2006, during the 2006 APS Users Meeting. The deadline for the receipt of complete nomination packages is February 15, 2006.

This award, which is presented every two years, was established in 2004 to recognize an important scientific or technical achievement by a young investigator (within two years of his or her Ph.D. degree) accomplished at or strongly beneficial to the APS. The award consists of a plaque and $1000. The award recipient will also be asked to present a 20-minute lecture on his or her research at the APS Users Meeting.

The award was named for Rosalind Franklin, who in the 1950s when she was in her early thirties, performed the x-ray crystallographic studies of DNA that were a critical contribution to the solution of the molecule's structure.

Complete nominating packages, including supporting letters, are due to Susan Strasser in the APS User Office by February 15, 2006. The recipient will be notified of the award by March 15, 2006, and an announcement will be issued in early April.

The APSUO web site provides a further description of the award, nominating instructions, and information about Alexis Templeton, the 2004 Franklin Award recipient.

8. Reviews Scheduled for 10 Sectors

As part of its ongoing assessment of science and operations, the APS Scientific Advisory Committee periodically reviews the performance of each sector. Reviews have been scheduled in 2006 for the following 10 sectors: 8 (ID lines), 10, 14, 15, 17, 19, 20, 22, 23, and 35.

If you work at one or more of these sectors, you may want to check the dates of the reviews and plan ahead. More than likely, the sector administrators will be asking for your help in preparing for the review. They may especially need your help in gathering publication information, which is entered in the APS publication database (where it helps the APS in facility-level reviews).

9. APS Offers New Information Products

-- Audio files in MP3 format. The APS is stepping into the new world of "podcasting"--that is, offering audio broadcasts for downloading. Our first collection of MP3 files include the audio from all APS Colloquia that have been captured as streaming video, as well as the audio from Murray Gibson's "Physics of the Blues" video. More audio files will be added in the future.

APS podcasts: http://www.aps.anl.gov/News/APS_Podcasts/
APS Colloquia streaming video: http://www.aps.anl.gov/video/APS_Colloquium/2005/

-- Images. A wide range of APS-related graphics and photos are now available from the image bank at lightsources.org. Material can be downloaded in high-resolution and PowerPoint-friendly file sizes. More are added all the time, so check back. A word of caution: go to the last page to see what's newest (the lightsources.org content management system catalogues these images latest-last).

Holiday Shutdown Affects Services

Argonne National Laboratory will be closed November 24-27 and December 23-January 2. If you need to be at Argonne during the holidays, please begin planning now. Services affected include site access, deliveries, the Guest House, and food service. Unless arrangements have been made in advance, you cannot enter the site or receive deliveries when the Laboratory is closed.

SPIE Scholarships and Career Guidance

A user has called to our attention that the International Society for Optical Engineering (SPIE) offers several kinds of educational support: four scholarships ranging from $2000 to $11,000, grants to educational institutions, and travel grants. The society also offers a CD on optics careers.
