Abstract : A method of amplifying electromagnetic oscillations with the aid of a closed or open electron flux moving in crossed electric and magnetic fields is presented. To improve the coefficient of amplification in connection with high efficient of the amplifier and a broad band of frequencies one one uses a retarding system which works in a mode of positive or negative dispersion in the form of two non-resonance sections not connected with each other or weakly connected by an electromagnetic field. An input UHF signal is passed into the retarding system to assure the fulfilling of the rule of buncher by one the sections which is the negative electrode. The second section which plays the role of the positive electrode (anode) of the amplifier and serves for selection of the potential energy from the bunched electron flux one arranges parallel to or concentric with the former with the shifting of the impedance surface in the direction of the electron flux movement. The electron flux is injected into the space of interaction at a short distance from the surface of the first section with the aid of a separate electron-optical system.
