Distributed amplification gyro traveling wave tube amplifier

Abstract

The invention discloses a distributed amplification gyro traveling wave tube amplifier, which consists of two sections, namely a linear amplification section with a structure alternatively loading by using a smooth circular waveguide and a loss medium waveguide and a nonlinear amplification section of the smooth circular waveguide, wherein the smooth circular waveguide in the linear section is synchronous to electron beams so as to generate electronic cyclotron maser interaction; a mode in the loss medium waveguide is asynchronous to the electron beams, so that net energy exchange does not exist and a high-frequency field is absorbed by a lossy material; and the electron beams interact in the smooth waveguide and drift in the loss waveguide. Therefore, the linear section is a pre-bunchingsection with high stability. Cyclotron electron beams are fully modulated by driven power in the linear section, well-bunched electron beams intensely act with a working mode in the nonlinear sectionand transverse kinetic energy is converted into microwave energy, so that high-energy microwave output is obtained. The loss medium waveguide of the linear section can effectively absorb a competition mode so as to ensure the stability of a device. The nonlinear section works by using pre-bunched electron beams, so that high power, high stability and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of microwave source devices, and is a cyclotron traveling wave tube amplifier adopting distributed amplification. Background technique [0002] In the late 1950s, the principle of electron cyclomaser interaction was discovered, and high-energy microwave sources based on this principle have been studied in depth both theoretically and experimentally. These high-energy microwave sources are used in today's radar communications, directed energy weapons, High gradient accelerators and other aspects have been widely used. The cyclotron traveling wave tube amplifier is an amplifier based on the principle of the electronic cyclotron maser. After nearly half a century of development, this type of device is still seriously affected by the stability and is difficult to realize engineering.
