Phase locking and frequency stabilizing gyrotron with periodic multiple-conductor structure

Abstract

The invention discloses a phase locking and frequency stabilizing gyrotron with a periodic multiple-conductor structure, and belongs to the technical field of high-power microwave and millimeter wave sources. The phase locking and frequency stabilizing gyrotron with the periodic multiple-conductor structure comprises a resonator, an output gradient waveguide and an even output waveguide, wherein the resonator is provided with an electron beam channel and injection waveguide holes. The phase locking and frequency stabilizing gyrotron with the periodic multiple-conductor structure is characterized in that in a resonant cavity of the resonator, at least three conductor structures are evenly arranged in the radial direction around the electron beam channel, and the injection waveguide holes are located between two adjacent conductor structures. The phase locking and frequency stabilizing gyrotron with the periodic multiple-conductor structure has the advantages that an injection signal can be effectively converted to a working mode of the gyrotron through the multiple-conductor structure, and therefore modulating actions are compulsorily conducted by electron beams according to the injection signal, the electron beams can only generate the modulation and the output of the injection signal, and an output signal achieves phase locking and frequency stabilizing.

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...

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.
