Abstract

The invention discloses a relativistic klystron amplifier (RKA) output cavity internally installed with a collector. The external diameter of an output cavity nose cone increases gradually from the input direction to the collector connection point. The inner diameter of the collector increases gradually from the output cavity nose cone connection point to the collector main body. The inner wall of an output cavity outer cylinder between supporting pillars and an output cavity end cover is provided with convex bench, and the three supporting pillars are uniformly distributed on the same circumference cross section in the output cavity outer cylinder. According to the relativistic klystron amplifier output cavity, the output cavity Q value is reduced under the condition of not reducing the angular uniformity of the electric field of the output cavity, thereby reducing the electric field intensity in the output cavity, reducing backflow electrons, reducing adverse impact of the backflow electrons on the working stability of a relativistic klystron amplifier, reducing power density of electron beams attacking the inner surface of the collector, reducing the generation of secondary electrons and other impurities, furthermore, preventing the secondary electrons and other impurities from escaping from the collector, and improving the RKA long pulse repeat frequency operation capability.

Description

technical field

[0001] The invention relates to the field of microwave electronics, in particular to a relativistic klystron amplifier output cavity with a built-in collector. Background technique

[0002] The relativistic klystron amplifier (RKA) is one of the most potential high-power microwave generating devices, which converts the energy of the electron beam into microwave energy through the interaction of the electron beam and the high-frequency field. In RKA, the grouping of electron beams and the microwave extraction process are completed in different areas, and each function can be adjusted to the best independently, so it has the advantages of high power and high efficiency. Among them, improving the stability of the relativistic klystron amplifier's long-pulse repetition frequency operation is one of the key points of the research.

[0003] At present, in the traditional cylindrical output cavity with a built-in collector, limited by the structure of the output ca...
