THE PHOTON COLLIDER AT TESLA

Abstract

High energy photon colliders (γγ,γe) are based on e - e - linear colliders where high energy photons are produced using Compton scattering of laser light on high energy electrons just before the interaction point. This paper is a part of the Technical Design Report of the linear collider TESLA. 1 Physics program, possible parameters and some technical aspects of the photon collider at TESLA are discussed.
