Gamma-gamma, gamma-electron colliders: physics, luminosities, background
arXiv:hep-ex/9910010
Abstract
This report on Photon Colliders covers the following ``physics'' issues: physics motivation, possible luminosities, backgrounds, plans of works and international cooperation. More technical aspects such as accelerator issues, new ideas on laser optics, laser cooling, and interaction region layout are discussed in my second talk at this Workshop.
