Abstract

The invention discloses an S-band three-cavity high-power microwave device, which includes a circular waveguide sleeve, and the circular waveguide sleeve is sequentially provided with a reflection cavity, a resonant cavity and an extraction cavity with the same inner diameter along the electron beam transmission direction. The cavity, resonant cavity and extraction cavity are annular grooves arranged on the circular waveguide sleeve; the annular electron beam with a voltage of 400kV and a beam intensity of 7.0kA is transmitted in the microwave device under the guidance of an axial magnetic field of 0.4T. One pulse time Internal radiation generates S-band high-power microwaves with a frequency of 2.4GHz. The S-band three-cavity high-power microwave device of the invention has the advantages of miniaturization, light weight and easy adjustment.

Description

technical field [0001] The invention relates to an S-band three-cavity high-power microwave device, belonging to the technical field of high-power microwave devices. Background technique [0002] High-power microwave generally refers to electromagnetic waves with peak power above 100MW and operating frequency in the range of 1-300GHz. With the development of high-power microwave research, higher and higher requirements are put forward for the total system efficiency of high-power microwave sources. [0003] The axial O-shaped high-power microwave device is a kind of high-power microwave device that is widely used due to the easy guidance of the electron beam brought by the structure and the variable combination of the structure. At present, the radiation generation of axial O-type high-power microwave devices generally requires a longer slow-wave structure to achieve synchronization of the phase velocity of the electron beam and the microwave. In the existing high-power mi...
