Abstract

The invention relates to a high-power microwave source device in the field of high-power microwave technology, in particular to a coaxial double annular cathode on-line adjusting device applied in RBWO, comprising a cathode rod, an outer cathode head, an inner cathode head, four radial rotary transmission rods, four axial rotary transmission rods, four axial horizontal transmission rods, four connecting pins, four radial adjustment bevel gears, four axial adjustment bevel gears and four servo motors. The whole structure is rotationally symmetrical about the central axis. The invention overcomes the complexity of frequency tuning RBWO regulation mode, By adjusting the extension and retraction of the inner and outer cathodes, the wide frequency spacing across X and Ka bands can be fine-tuned, and the dual-band output can be realized simultaneously. It is of great significance for the design of this type of devices.

Description

technical field [0001] The invention relates to a high-power microwave source device in the technical field of high-power microwaves, in particular to a coaxial double-ring cathode online adjustment device used in a relativistic back-wave oscillator (relativistic back-wave oscillator, RBWO for short). Background technique [0002] High-power microwave generally refers to electromagnetic waves with a power greater than 100MW and a frequency between 0.1GHz and 100GHz. High-power microwave sources refer to relativistic electric vacuum devices used to generate high-power microwaves, most of which are driven by high-current relativistic electron beams. In the past two decades, driven by applications such as plasma thermonuclear fusion, high-power radar, high-energy radio frequency accelerators, directed energy weapons, and space-to-earth power transmission, high-power microwave source technology has developed rapidly. [0003] Frequency tunability is one of the important develop...
