Using the next e

1975 is the start in France for "Communication Studies". How many people in 2001 this new discipline represents? More than 1000 permanent professors (including lecturers and adjoints), increasing ...each year by more than 10% since its creation. What kind of theme they work on? "General Theories" for 15%, "New Medias" for 14%, "Communicational skill" for 11%, "Organizational Communication" for 10%, "Bibliology" for 9%, etc. An incredible vivid field.

To reach design luminosity, the International Linear Collider (ILC) must be able to create and reliably maintain nanometer size beams. The ATF damping ring is the unique facility where ILC emittances ...are possible. In this paper we present and evaluate the proposal to create a final focus facility at the ATF which, using compact final focus optics and an ILC-like bunch train, would be capable of achieving 37 nm beam size. Such a facility would enable the development of beam diagnostics and tuning methods, as well as the training of young accelerator physicists.
We derive formulas which describe the interaction of laser beams with electron beams. Specializing to the case of 1-TeV electron beams from the future generation of electron linear accelerators, we ...calculate the production rate of backscattered 1-TeV photons, and using these photons, we show that it is possible to organize the photoproduction of beauty particles so as to measure 10{sup 9} {ital b{bar b}} pairs per year. This should be adequate to study rare decays and {ital CP} violation in {ital B} meson decay.
