Theory of a multiwave amplifier using relativistic cyclotron oscillators
Abstract
Physical processes in a multiwave amplifier with relativistic electron cyclotron oscillators are analyzed through numerical simulation with reference to masers and free-electron lasers. It is shown that amplification with an energy conversion efficiency of about 50 percent and a gain of about 50 dB can be obtained. The system is characterized by a narrow radiation pattern of the amplified radiation, depending on the geometric parameters of the relativistic beam and the electron energy. The polarization of the radiation is independent of the input-signal polarization and depends mainly on the coherent interaction of beam electrons.
