DEVELOPMENT OF THEORY OF FREE ELECTRON LASER AMPLIFIER WITH AZIMUTHAL-SYMMETRIC ELECTRON BEAM AND INVESTIGATION OF POSSIBILITY TO APPLY FREE ELECTRON LASERS (FEL) FOR CREATION OF GAMMA-GAMMA COLLIDERS

The theory of the FEL-amplifier with azimuthal-symmetric electron beam permitting to describe the linear and non-linear operation mode has been stated. The detailed physical analysis of the special operation features in the FEL-amplifier with azimuthal-symmetric electron beam has been made. The technique of applying similarity methods in the theory of FEL-amplifier with azimuthal-symmetric electron beam has been developed. The analysis a possibility to use the FEL technique for creation of the gamma-gamma colliders for TeV-energy range has been given. The two-stage circuit of FEL as a source of the primary photons for gamma-gamma collider has been proposed. The optimization of the FEL-amplifier parameters has been made, the requirements for the driver electron beam parameters and undulator parameters have been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
