RF-power upgrade systems with energy compression for electron linacs

Application of the RF-energy compression systems as an RF-source for linear charged particles accelerators is represented to be rather perspective, as far as they permit to increase pulsed power of accelerating wave without application of any additional or more powerful RF-generators and, hence, to increase an output beam energy of an accelerator. More over, application of such systems enables an essential expand of a beam energy adjustment range, that in some cases permits to use only one unit instead of a number. The authors discuss classification of the energy compression systems (ECS), that may be used as the RF-feed sources for electron linacs
