چکیده
Using the laser backscattering method at future TeV linear colliders one can obtain γγ and γe colliding beams (photon colliders) with the energy and luminosity comparable to that in ee collisions. Now this option is included to conceptual designs of linear colliders. This paper (talk at the conference on nonlinear optics) is a short introduction to this field with an emphasis on required lasers which can be used both for e → γ conversion and for preparation of electron beams (photoguns, laser cooling), some interesting nonlinear QED effects in a strong field which apply restrictions on parameters of photon colliders are discussed.

Last two years were very important in history of a photon colliders. This option is included now in conceptual design reports of the NLC, JLC and TESLA/SBLC projects. All the designs foresee two interaction regions: one for ee and the second for γγ, γe and ee collisions. This paper is focused on three aspects: 1) arguments for photon colliders; 2) parameters of current projects; 3) ultimate lum...

In this review we consider three important applications of lasers in high energy physics: γγ, γe colliders, laser cooling, positron production. These topics are actual now due to plans of construction linear ee, ee, γγ, γe colliders with energies 0.3–1 TeV. High energy photons for γγ, γe collisions can be obtained using laser backscattering. These types of collisions considerably increase physi...

متن کامل0 Budker INP 2000 - 22 Photon colliders : key problems , new ideas ∗
High energy photon colliders based on laser backscattering are a very natural extension of a ee linear colliders and open new possibilities to study of the matter. This option has been included in the pre-conceptual designs of linear colliders and work on Technical Design Reports is in progress. The physics motivation for photon colliders is quite clear though more studies are needed. The proof...

It is very likely that in 3-4 years the construction of one or two linear colliders with c.m.s energy up to 0.5–1.5 TeV will be started. Besides eecollisions, linear colliders give a unique possibility to study γγ and γe interactions at energies and luminosities comparable to those in ee collisions. High energy photons for γγ and γe collisions can be obtained using laser backscattering. These t...
