1. Determination of High-Resolution Ribosome Structure Provides New Information on Protein Formation

(Contact: andrzejj@anl.gov)

Recent work at the APS Structural Biology Center-CAT undulator beamline 19-ID allowed a research team from the Medical Research Council Laboratory of Molecular Biology in the United Kingdom to obtain new insights into the mechanism through which the ribosome enables translation of the genetic code into proteins. A brief summary of this work with links to the complete paper, which was published in the May 4, 2001, issue of the journal Science, can be found at the following Web address: (http://www.aps.anl.gov/apsimage/ribsomemain.html)

A listing of additional Research Highlights can be accessed through the APS Web Home Page (http://www.aps.anl.gov/). New highlights are added regularly, and a different one is displayed each time the APS Home Page is accessed.

Synchrotron Users Organization Representatives Visit Capitol Hill

(Contact: isaacs@lucent.com)

Eric Isaacs, Chair of the APS Users Organization, and colleagues from each of the other three U.S. DOE synchrotron users organizations (Roger Falcone from the Advanced Light Source, Simon Bare from the National Synchrotron Light Source, and Paul Foster from the Stanford Synchrotron Radiation Laboratory) recently headed to Capital Hill to discuss funding for the physical sciences. On May 7, they met with Congressional staffers for members of the Senate Energy and Water Appropriations Committee, the House Energy and Water Appropriations Committee, and the House Science Committee. These staffers were briefed on the significant scientific, technological, educational, and economic contributions made by the four synchrotron research facilities and their users, as well as on the need both for adequate financial support for these facilities and for research in the physical sciences in general. On May 8, they met with staffers from the Office of Science and Technology Policy and the Office of Management and Budget. The focus of these meetings was the FY 2003 budget. Another series of meeting with individual senators and congressmen is planned for mid to late June.

APS Compton Award Nominations due June 30, 2001

(Contact: strasser@aps.anl.gov)

In conjunction with the Advanced Photon Source, the APS Users Organization has established the APS Compton Award to recognize an important technical or scientific accomplishment at, or beneficial to, the APS. The fifth award, which consists of a plaque plus a monetary award of $2500 will be presented at the Eleventh APS Users Meeting, on October 10, 2001. (If the work was accomplished by more than one individual, the award may be shared.) The recipient (or recipients) of the award will be asked to present a plenary lecture at this meeting.

Nominations for this award must include the following:

  • A one-page description of the work for which the award is proposed
  • A statement describing the significant and impact of the work
  • A short proposed citation
  • Names of two individuals who have agreed to write supporting letters
  • The signature of the nominator

Please note: It is the responsibility of the nominator to request supporting letters, which should be sent under separate cover. Complete packages (nominating information and letters) must be received no later than June 30, 2001. The award recipient will be notified no later than August 15, 2001.

Nominating packages and letters should be sent to

Susan Barr Strasser
APS User Office, Building 401
Argonne National Laboratory
9700 South Cass Avenue
Argonne, Illinois 60439

4. Upgrades Announced to Submission Process for Experiment Safety Approval Forms

(Contact: glagola@aps.anl.gov)

As of Monday, May 7, 2001, the Web-based submission process allows users to create an Experiment Safety Approval Form (ESAF) in more than one sitting, as well as modify forms that have already been submitted. To enable this upgrade, the log-in screen for the ESAF submission process now requires a user badge number. When they log in, users will be able to call up a listing of all ESAFs attached to their badges numbers. Details of the process, as well as a link to Frequently Asked Questions (FAQs), are available on the ESAF submittal web page: http://www.aps.anl.gov/xfd/tech/esafwww/esaf.html

Questions about the ESAF submission process and upgrades should be addressed to Bruce Glagola, User Safety Coordinator, at 630.252.9797 or glagola@aps.anl.gov.

5. Conference and Meeting Information for APS Users Available on Web Site

(Contact: strasser@aps.anl.gov)

The Web site listing selecting meetings and conferences of interest to APS users can be found at the following Web address: http://www.aps.anl.gov/conferences.html

This site, which is updated regularly, contains links to more detailed information about each meeting. If you are involved with a conference or meeting that is of potential interest to APS users and would like to have it listed on this site, contact Susan Strasser (strasser@aps.anl.gov).

6. Operations Update

(Contact: avr@aps.anl.gov)

During April, the APS conducted significant maintenance, installation and upgrade activities in all parts of the accelerator systems. Most notable was the complete installation of the improved timing system for the storage ring rf beam position monitors. The timing system not only improves the stability of the position monitors, but also, once fully commissioned, will remove the need to have the six bunch timing group as part of the storage ring fill pattern, which will allow increased flexibility in filling patterns for the storage ring, such as having a uniform, equidistant singlet fill.

Another significant activity was the completion and integration into the storage ring of the sector 22 (SER-CAT) ID beamline front-end. Initial shielding validation and initial commissioning for this beamline will take place during the current user run, which began May 9th.
