Abstract

The invention relates to a microwave source apparatus in the technical field of high-power microwaves, in particular an X-waveband high-impedance relativity theory klystron amplifier adopting an annular beam cold cathode. The X-waveband high-impedance relativity theory klystron amplifier is composed of a cathode, a cathode shielding ring, an anode outer cylinder, a high frequency signal injection port, injected waveguide, a resonant cavity, a drift tube, a coaxial extracting structure, a collector, a studdle and a permanent magnetic field; the disadvantages that the traditional high-impedance RKA electronic optical system based on a hot cathode needs an extra heating device and is large in energy consumption, and the system is huge, complex and bad for processing and experimenting are overcome, and the traditional foilless diode is hard to produce the high-impedance annular electronic beam in kOmega level; an annular beam cold cathode with the shielding ring is designed to apply to the X-waveband high-impedance RKA adopting the permanent magnet package, so that the electronic optical system of the microwave tube is simple and compact in structure and easy to process and experiment.

Description

technical field [0001] The invention relates to a microwave source device in the technical field of high-power microwave (HPM), in particular to an X-band high-impedance relativistic klystron amplifier (Relativtistic Klystron Amplifier, RKA) using a ring-beam cold cathode. Background technique [0002] In recent years, the attractive prospect of high-power microwave (HPM) (according to the agreement of Benford and Swegle, high-power microwave refers to electromagnetic waves with a peak power greater than 100MW and a frequency between 1 and 300GHz) in many fields has attracted widespread attention in many countries. Attention and heavy research investment. As the core device of the high-power microwave system, the high-power microwave source uses the electron beam emitted by the cathode to interact with the resonant mode of the internal cavity of the device, and then radiates high-power microwaves. In order to further meet the application requirements, it is one of the most ...
