Abstract

The invention discloses an angular power division waveguide structure applied to a medium-loaded cyclotron traveling wave tube, and relates to the technical field of microwave and millimeter wave electric vacuum devices. The angular power splitting waveguide structure of the present invention is arranged between the medium loading interaction section and the output waveguide section; the angular power splitting waveguide structure includes: a circular waveguide, N forward angular power splitting waveguides, and N reverse angular power splitting waveguides Split waveguide; the forward angular power split waveguide is an oblique-out rectangular waveguide uniformly distributed along the outer wall of the circular waveguide, and the reverse angular power split waveguide is an oblique-entry rectangular waveguide evenly distributed angularly along the outer wall of the circular waveguide. After the electromagnetic wave generated by the gyrotron traveling wave tube in the pre-grouping stage enters the angular power splitting waveguide structure, most of the electromagnetic wave energy directly propagates into the angular power splitting waveguide, and then is absorbed by the wave-absorbing structure; the angular power splitting waveguide structure The dissipation area is increased, the average power capacity of the gyrotraveling wave tube is improved, and the angular power division waveguide structure also effectively shortens the length of the medium loading section.

Description

technical field [0001] The invention relates to the technical field of microwave and millimeter wave electric vacuum devices, in particular to an angular power division waveguide structure applied to a medium-loaded gyrotraveling wave tube. Background technique [0002] The gyrotron is an important high-power millimeter-wave source. It has the characteristics of broadband and high power, and has broad application prospects in military and civilian fields such as radar, communication, electronic countermeasures, material processing, controlled thermonuclear fusion plasma heating, and environmental protection, so it has been highly valued internationally and domestically. [0003] After years of development, the gyro-traveling-wave tube has derived a variety of tubular structures, among which the gyro-traveling-wave tube with a medium-loaded structure is a very successful gyro-traveling-wave tube structure. The gyro-traveling-wave tube includes sequentially connected input wav...
