Problems solved by technology

This frequency adjustable technology requires the pulse power source to have a large voltage adjustment range, but when the device outputs high-power microwaves, the electron beam speed in the device is close to the speed of light, so it is very insensitive to voltage changes, and the general pulse source also only provide limited voltage regulation capability

Abstract

Disclosed in the invention is a multi-frequency controllable high-power microwave device comprising a vacuum cavity formed by vacuum and sealed connection of a high-power microwave device, a device slow-wave-structure period adjusting mechanism, an insulator, a microwave radiation antenna and a guide magnet. The high-power microwave device consists of a cathode, a drift cavity, a beam wave interaction cavity, and a microwave output cavity; the beam wave interaction cavity is characterized in that a plurality of disk-loaded waveguide plates with central holes form a uniform periodic slow-wave structure; and the disk-loaded waveguide plates with central holes are connected in series with the device slow-wave-structure period adjusting mechanism by a threaded hole to form a uniform disk-loaded waveguide period adjusting device. With the uniform disk-loaded waveguide period adjusting device, the on-line, remote, and adjustable effect for the frequency of the high-power microwave device is realized; and high-power microwave outputs with different frequencies for the single device can be realized successively.

Description

technical field [0001] The patent of the present invention relates to the technical field of high-power microwave devices, in particular to a multi-frequency controllable high-power microwave device device. Background technique [0002] High-power microwave (HPM) generally refers to electromagnetic waves with a peak power above 100MW and an operating frequency in the range of 100MHz to 300GHz. At present, the generation of high-power microwaves generally relies on high-energy relativistic electron beams. Microwave oscillations are generated by the interaction of the return wave in the slow-wave structure and the electron beam. The electron beam is accelerated to a speed close to the speed of light in this type of device. High energy, the microwave in the tube obtains the energy of the electron beam through the beam-wave interaction, thereby generating microwave amplification. The relativistic back-wave oscillator is essentially a surface wave device, which utilizes the reso...
