4th International Workshop on
ELECTRON-ELECTRON INTERACTIONS

2nd Bulletin
Our first Bulletin was sent a couple of weeks before the nerve- wracking events of September 11. By this time, conditions have sufficiently normalized so we can structure our Workshop with a good deal of confidence; it is, however, not yet possible to give you a preliminary scientific program with talks and time allotments, given the uncertainty in establishing travel plans. We therefore urge all of you to communicate your plans and the contributions you may be able to present to our meeting as soon as possible. Irrespective of precise scheduling, however, we would like to give you all the organizational details that may facilitate your planning, in addition to the skeleton of the scientific structuring of the physics arguments that make the presence of its electron-electron version from day one of the Linear Collider, both in its own right and in its guise of irreplaceable parent of the e-gamma and gamma-gamma versions of this machine, a vital part of our next major accelerator project.

As of now, we plan to structure the presentations and discussions of our three-day meeting along the following lines:

Friday, December 7: The physics urgency for providing e-e- collisions with precisely known and easily changed parameters as soon as possible upon inauguration of the Linear Collider. There has been a wealth of new ideas since our last workshop; and the development of powerful simulation packages that incorporate signal-to-background evaluations as well as radiative and QCD corrections permits a greatly improved preview of the promise of many searches with given amounts of integrated luminosity. Projects that appeared highly tentative only two years ago can now be proposed with considerable confidence.

Saturday, December 8: Machine, Interaction Region, Detector issues: The demands on the qualities of the beams and their available luminosities make it advisable to look at the need for an optimization of beam parameters in all proposed LC configurations - TESLA, NLC/JLC, CLIC - including the "overhead" for installing the e-e- version together with the e+e- configuration, and for providing minimal switchover difficulties. The estimates of how well the highest available polarization of the beams can be measured and what IR backgrounds have to be accepted will help to define the program that can be foreseen.

Sunday, December 9: Physics and technological developments in the e-gamma and gamma-gamma channel of the Linear Collider: a number of the most active physics issues, such as the search for evidence for extra dimensions, show the greatest promise in one of these modes. Fortunately, there is now solid progress in the configuration of laser backscattering equipment such hat an integration into LC design becomes realistic. The precision with which monochromaticity and polarization of the resulting high-energy photon beams can be produced is redefining this field.

And, of course, Sunday will give us a chance to have discussions of where we stand, what tasks must be seen as particularly urgent, and how best we can assure the full complementarity of the different running modes of the Linear Collider.

INFORMATION ON LOCAL ARRANGEMENTS:

WORKSHOP LOCATION on campus is Natural Sciences Annex, Room 101. See the map on our website.

The SCIPP OFFICE is in Natural Sciences 2, Room 308, located on the west end of the building---the end closest to the meeting room, but two floors up. Computer access will be available here.

REGISTRATION: As in previous years, we will not levy a registration fee for the workshop; however, we do require a registration form, located below.

WEBSITE: The full website will be up and running as of Nov. 1, 01.

BANQUET: We are planning to host an evening of good food and a chamber music offering at the Inn at Pasatiempo on Friday evening, beginning at 7pm with no-host cocktails.

SUNDAY ACTIVITY: We are also attempting to organize a Sunday afternoon tour of Natural Bridges State Park, a local beach which features the Monarch Grove preserve, housing thousands of the migrating butterflies that are featured on our poster - a movable Santa Cruz landmark.

CAR RENTAL information at the two airports and LODGING recommendations can be accessed from the e-e- Web site.

PARKING: We encourage car-pooling from the hotels to campus in order to lessen the impact on the campus and make it easier on those of you who do drive to find parking. Although the campus will be between quarters, finding parking has become extremely difficult near the Natural Sciences 2 building, due to closing of several lots nearby. Detailed instructions are given on the Parking page on our web site as well as a map of the campus parking lots.

We will provide permits for Friday to those who check the box on the registration form. You can park your car and come up very quickly to the office for your permit. No permits are needed for Saturday or Sunday in most lots, however some lots and the nearby parking garage require permits at all times - so be aware of these, or you could be ticketed. Again, consult the map for the lots available to you.

People coming from SLAC or Bay Area: Please do car-pool as much as you can. Let me know who will need the permit. All U.C. campus parking permits will be honored.

TRANSPARENCIES: Please bring copies of your transparencies with you. If you wish copies of certain talks, we will be glad to provide them. Copies of complete sets will be sent to major institutions only: SLAC, Fermilab, DESY, CERN, KEK.

A PROCEEDINGS volume will be published as a special issue of the International Journal of Modern Physics A. Camera-ready copy deadline is March 3, 2002. Author's instructions will be posted on our Web site.
