Abstract

The invention discloses a same frequency heterotypical cyclotron traveling wave klystron amplifier which is characterized by comprising an input cavity, no or a plurality of bunching cavities, one or more drift segments and a traveling wave amplification segment. The input cavity, the bunching cavities and the traveling wave amplification segment are respectively connected with drift segments to form a whole. The input cavity, the bunching cavities and the traveling wave amplification segment of the same frequency heterotypical cyclotron traveling wave klystron amplifier work at the same harmonic and the same frequency, with the same working waveguide mode angular orientation index. The input cavity, the bunching cavities of the same frequency heterotypical cyclotron traveling wave klystron amplifier work under the same waveguide mode with lower order, while the traveling wave amplification segment work under the waveguide mode with higher order than the input cavity.

Description

technical field [0001] The invention relates to a gyrotwystron amplifier (gyrotwystron) with the same frequency and different modes, belonging to the technical field of high-power millimeter wave sources. Background technique [0002] High-power millimeter-wave radar has very important application prospects in national defense fields such as high-resolution radar imaging, anti-stealth, anti-low-altitude flying targets, anti-sea-skimming missiles, missile defense, and electronic countermeasures. Civilian fields such as high-energy physics also have good application prospects. To develop high-power millimeter-wave radar, it is necessary to develop a high-power millimeter-wave source first. Traditional vacuum electronic devices have encountered great difficulties in the millimeter-wave frequency band. And the gyrotron (1.Twiss R.Q., Roberts J.A.Electromagnetic radiation from electrons rotating in an ionized medium under the action of a uniform magnetic field.Aust.J.Phys.1958,1...
