Problems solved by technology

[0004] (1) Traditional high-power klystrons have relatively large power and gain, but in applications such as radar, too narrow a bandwidth will directly affect the anti-interference ability, resolution and sensitivity of the radar;
[0005] (2) The output power of traditional high-power klystrons is limited, which greatly affects the detection range of radar and high-resolution radar imaging
[0006] Although the power of the high-power klystron developed at present has been improved to a certain extent, it cannot really realize the output of broadband power, and it cannot really improve the anti-jamming ability, resolution and sensitivity of the radar.

Abstract

The invention provides an S-waveband 12.1% bandwidth klystron which comprises an electron gun assembly, a cluster segment assembly and an output segment assembly. The electron gun assembly is used for emitting an electron beam which moves forwards along a drift channel under the constraint of a magnetic field; the cluster segment assembly modulates the speed and density of the electron beam emitted by the electron gun assembly to generate a high-frequency electron beam; and the output segment assembly makes beam-wave interaction with the high-frequency electron beam provided by the cluster segment assembly, wherein energy of the electron beam is converted into microwaves in an output cavity, and the microwaves are output. The S-waveband 12.1% bandwidth klystron has unique advantages in the aspects of improving the bandwidth and power.

Description

technical field [0001] The invention relates to the field of electric vacuum technology, in particular to an S-band 12.1% bandwidth high-power klystron. Background technique [0002] In the large family of microwave electric vacuum devices, the klystron is one of them. It is an electronic device that uses charged particles to oscillate or amplify microwave signals during the movement between electrodes in a vacuum state. Ordinary klystrons have the characteristics of high power, high gain and high efficiency. Compared with other microwave tubes, bandwidth is not the advantage of klystrons. However, the output power level of the klystron is the highest among microwave tubes. As the core device of the radar transmitter, it plays a vital role in applications such as electronic countermeasures, free electron laser weapons and radar imaging. In order to improve the anti-interference ability and sensitivity of the radar, not only the power and gain of the klystron are high, but a...
