The CLIC study of a 0.5 to 5 TeV $e^{+}e^{-}$ linear collider

About

This lectures begin with a general introduction on $e^{+/-}$ linear colliders as well as the various technologies presently developed all over the world and continue with general scaling laws for linear collider parametrisation. The lectures then focus on the study of a high energy (0.5 to 5 TeV), high luminosity $(10^{34}$ to $10^{35}cm^{2}S^{-1}$ compact linear collider(CLIC) CLIC is based on normal conducting travelling-wave accelerating structures at high frequency (30 GHz) operating at high fields (100 to 200 MeV/m). High frequency structures allow high accelerating gradients but cannot be powered by conventional RF source. A novel and efficient method for RF power generation using an a auxiliary high current-low energy electron beam, the so-called "Two Beam Acceleration" scheme is described and compared with traditional RF power production techniques. Finally, recent 30 GHz hardware developments and experimental results from the CLIC Test Facility assessing the feasibility of the scheme are presented..
