Quantum Beamstrahlung: Prospects for a Photon-Photon Collider

Abstract
In this paper the treatment of radiation in pulse-pulse collisions relevant to high-energy electron-positron colliders is extended to multiple-photon processes. The resultant multiple-photon spectrum is hard. We discuss the possibility of a photon-photon collider utilizing this radiation. The expected flux is calculated and turns out to be from 1 to 2 orders of magnitude larger than that of the conventional virtual-two-photon source, depending upon machine parameters. Photon-electron processes are also enhanced by this additional hard-photon source.
