Linear colliders: Accelerator physics aspects, problems, options, prospects

Abstract In the lecture, I will try to present the very interesting field of linear colliders—the real way to many hundreds of GeV center-of-mass energies for lepton-antilepton collisions, namely electron-positron ones, and related topics. I wish, you understood—the money are important for elementary particles physics experimental progress, but it is not all. In the area, there is a lot of interesting accelerator physics, and a lot of room for non-trivial inventiveness.
