1. Workshop: Operating Modes--What Are the Tradeoffs?
(Contact: klaffky@aps.anl.gov)

The move in FY2002 to top-up operation proved very successful for both the accelerator staff and users. To build on that experience, the APS is interested in talking with users about the best ways to use this and other possible operating modes to both accommodate the broad spectrum of user needs and permit continuous improvement of the facility. With this goal in mind, the APS will host a half-day workshop on operating modes on Wednesday, November 6, 2002. At the workshop, APS staff and users will explore the many ways that the APS can provide photons, as well as the advantages and tradeoffs involved. First, APS staff will discuss the capabilities of the machine and the operational considerations that guide decisions about which modes are scheduled. Next, users can present their needs for particular types of operation. The workshop will begin at 8:00 a.m. in Bldg. 401, Room E1100/E1200. Please contact Barb Dalton if you plan to attend (dalton@aps.anl.gov).

2. Workshop: Beyond Undulator A--New Directions and New Needs for Insertion Devices
(Contact: sasaki@aps.anl.gov)

What is possible in next-generation insertion devices at the APS? What insertion devices do users need? These questions will be the focus of a joint APS/user workshop on December 5, 2002, at the APS to set new directions for development of insertion devices. User viewpoints will be particularly important in helping the APS set priorities for future work. The day will feature talks on possible new devices, the limitations on straight section length and minimum gap, and international developments. An initial agenda is available at http://www.aps.anl.gov/conferences/novel_ids/agenda.html. If you have particular need for a new device and would like to give a short (10 minute) presentation describing its ideal characteristics (energy, polarization, brightness, flux, tunability, etc.), please contact the organizers (Shigemi Sasaki, sasaki@aps.anl.gov; John Hill, hill@bnl.gov; Liz Moog, moog@aps.anl.gov) about getting a spot on the agenda.

3. New on the Floor: APS Introduces Locator Cards
(Contact: klaffky@aps.anl.gov)

If you’ve been on the experiment floor recently, you may have noticed small green cards posted on experiment stations. The APS is asking users to complete these "locator cards" with contact information whenever they will be away from the beamline for more than an hour. The card should indicate who is currently using the beamline. These cards help beamline staff track the status of the beamline and allow them to locate the proper person in case of a safety or equipment problem that could affect your experiment. We appreciate your help in completing these cards.

4. Reminder: General User Proposals Due Nov. 1
(Contact: jandrew@aps.anl.gov)

Proposals for general user time during run 2003-1 (January 29-April 20, 2003) are due November 1 and must be submitted though our new web-based proposal system: http://beam.aps.anl.gov/pls/apsweb/gup0005.start_page. For questions or problems, send email to gu_program@aps.anl.gov.

5. Reminder: Non-U.S. Citizen Users Need New Badges
(Contact: strasser@aps.anl.gov)

APS user badges for non-U.S. citizens must now display, on the front, the date on which the user’s access permission expires. (Note: This change does not apply to Argonne badges for APS employees.) This expiration date is determined by the approval date on the access permission form that the User Office files with the Department of Energy. If you need a new badge, please contact the User Office (apsuser@aps.anl.gov, 630-252-9090) BEFORE you travel to the APS. We’ll make appropriate arrangements so you can enter the site and get a new badge without delay.
