Problems solved by technology

Because the temperature of the traditional gyrotron will rise during operation, the inner diameter of the resonant cavity will change, which will cause the frequency emission drift of the working mode, resulting in the frequency locking of the output frequency drift. The voltage and current control cannot effectively stabilize the frequency, so it is usually not used. Feedback phase-locking method, while injection phase-locking method
However, in order to obtain high power output, the gyrotron often works in a high-order mode. It is difficult to convert the injected signal into the required working mode by using the traditional gyrotron structure, so it is impossible to achieve phase-locked and frequency-stabilized work.

Abstract

A phase-locked frequency-stabilized gyrotron with a periodic multi-conductor structure belongs to the technical field of high-power microwave and millimeter wave sources. The invention includes a resonator with an electron beam channel and an injection waveguide hole, an output gradient waveguide, and an output uniform waveguide, and is characterized in that, in the resonant cavity of the resonator, at least 3 Conductor structures, the injection waveguide holes are located between two adjacent conductor structures. The beneficial effect of the present invention is that the injection signal can be effectively converted into the working mode of the gyrotron through the multi-conductor structure, so that the electron beam is forced to perform modulation according to the injection signal, so that the electron beam can only produce modulation of the injection signal in the resonant cavity Generate an output, so that the output signal achieves phase-locking and frequency stabilization.

Description

technical field [0001] The invention relates to a phase-locked frequency-stabilized gyrotron with a periodic multi-conductor structure, belonging to the technical field of high-power microwave and millimeter wave sources. Background technique [0002] In the late 1950s, Australian astronomer Twiss proposed a new concept of electron cyclotron resonance stimulated radiation through the observation of the ionosphere absorbing electromagnetic waves. At about the same time, the American scientist Schneider and the former Soviet scientist Gaponov also independently proposed a new concept of the interaction between the spiral electron beam moving in the magnetic field and the electromagnetic wave when considering the relativistic effect. In the mid-1960s, the American scientist Hirshfield fully confirmed the mechanism of the electron cyclotron maser through experiments. On this basis, scientists in the former Soviet Union successfully developed a microwave device-gyrotron with the...
