[0024] The basic working principle of the multi-antenna coupling output structure relativistic magnetron of the present invention is similar to the magnetron of the traditional structure, and the electrons emitted by the cathode interact with the beam waves of the high-frequency field microwave in the resonant cavity to exchange energy, so that the electrons The energy of the microwave is converted into the energy of the microwave, and the microwave energy is amplified. The biggest difference lies in the...

Abstract

The invention discloses a relativistic magnetron for a multi-antenna coupling output structure, and the relativistic magnetron comprises a cathode, an anode outer bushing, and an anode block which is disposed in the anode outer bushing. The cathode is disposed in the anode outer bushing in a coaxial manner. The anode block is disposed between the cathode and the anode outer bushing, and is connected with the inner wall of the anode outer bushing. The interior of the anode outer bushing is provided with a coupling antenna, wherein one end of the coupling antenna is connected with the anode block, and the other end of the coupling antenna is suspended. The coupling antenna is axially parallel to the anode outer bushing. Because a method for placing the coupling antenna inside is employed, the whole output structure extends in the axial direction of the cathode and anode and the lateral size of a system is just determined by the cathode and anode of a microwave tube, the structure is more compact. Moreover, the output structure cannot additionally increase the lateral size of the microwave tube, thereby facilitating the miniature design of an external magnetic field generation system. In addition, the output mode of the relativistic magnetron can be change according to the needs.

Description

technical field [0001] The invention belongs to the technical field of high-power microwaves, and in particular relates to a relativistic magnetron with a multi-antenna coupling output structure. The invention can be applied to a microwave generation system in the technical field of high-power microwaves. Background technique [0002] With the development of high-power microwave technology, the research of high-power microwave technology is increasingly considering the actual application requirements, which puts forward higher requirements for the miniaturization and lightweight design of high-power microwave devices. [0003] Relativistic Magnetron (referred to as RM) is one of the important high-power microwave tubes, which is a direct extrapolation of ordinary magnetrons in the direction of high voltage and high current. At present, the research focus of the relativistic magnetron is to maximize the efficiency and reduce the volume and weight of the system to meet the nee...
