Title: Requirements to beam emittances at photon colliders. Laser cooling of electron beams

Abstract

Linear colliders offer unique opportunity to study {gamma}{gamma},{gamma}e interactions. Using the laser backscattering method one can obtain {gamma}{gamma} and {gamma}e colliding beams with the energy and luminosity comparable to that in e{sup +}e{sup {minus}} collisions or even higher (due to absence of some beam collision effects). In order to reach ultimate parameters of photon colliders the {open_quotes}geometric{close_quotes} luminosity of initial electron beams should be higher than that in e{sup +}e{sup {minus}} collisions. In this report requirements to beam emittances at photon colliders are analyzed and a novel method of obtaining electron beams with small transverse emittances is considered: the electron beam is cooled during a head-on collision with the focused powerful laser pulse. With reasonable laser parameters (laser flash energy about 10 J) one can decrease the transverse normalized emittances by a factor of 10 per one stage. A limit on the final (after few stages) transverse emittance of the electron beam is much lower than that given by other known methods. {copyright} {ital 1997 American Institute of Physics.}
