Abstract

The invention discloses a waveguide switch for switching the transmission direction of a high-power electron cyclotron wave. The waveguide switch comprises a waveguide switch cavity, a reflector, a driving motor and first to fifth straight-through circular waveguide sections with the same size; the centers of the front, rear, left, right and top surfaces of the waveguide switch cavity are providedwith circular holes with the same size; and the circular holes are in butt joint with the first through circular waveguide section, the second through circular waveguide section, the third through circular waveguide section, the fourth through circular waveguide section and the fifth through circular waveguide section respectively, the reflector is arranged in the waveguide switch cavity, rapid switching among four transmission directions can be achieved, and the design can meet the requirement of a large Tokamak device for rapid switching among multiple ECRH systems. Besides, the waveguide switch is simple in structure and low in processing difficulty, and the ellipsoidal mirror surface design of the reflecting mirror surface enables high-power electron cyclotron waves to have no obviousdivergence in beam radius before and after passing through the waveguide switch, so that the transmission is efficient and stable.

Description

technical field [0001] The invention belongs to the field of microwave technology, and more specifically relates to a waveguide switch for switching the transmission direction of high-power electronic cyclotron waves. Background technique [0002] Electron Cyclotron Resonance Heating (ECRH, Electron Cyclotron Resonance Heating) is a widely used plasma heating method in the current experimental research of magnetic confinement controlled thermonuclear fusion, which has good heating effect, good heating locality, current The drive efficiency is high, the antenna can be far away from the plasma and so on. The ECRH system is mainly composed of wave source system, transmission system, antenna system, control and protection system, etc. The power of a single system is usually between 200kW and 1MW. Common ECRH system operating frequency range is 30-200GHz. Now consider the following two situations: 1. Large-scale tokamak devices are usually equipped with several sets of ECRH sys...
