Abstract

The invention belongs to the technical field of microwave sources in the high-power microwave technology, and particularly relates to a relativistic magnetron with the rectangular TE10 output mode. According to the relativistic magnetron with the rectangular TE10 output mode, the axial output microwave mode can be purer, and a whole system can be compacter. The novel relativistic magnetron is provided for solving the problems that an existing axial output relativistic magnetron needs the purer single output mode and can not meet the requirements in the aspects such as compacting and miniaturizing. According to the relativistic magnetron, due to the improvement on the structure of anodes of the relativistic magnetron, the design of an axial output transition section, the design of a rectangular output waveguide and the design of an external magnetic field system, purer microwaves in the rectangular TE10 mode can be directly and axially output, and the whole system can be compact and minimized.

Description

technical field [0001] The invention belongs to the technical field of microwave sources in high-power microwave technology, and specifically relates to a relativistic magnetron with TE10 output mode which can make the microwave mode output in the axial direction more pure and the whole system more compact. Background technique [0002] From the perspective of developing a practical high-power microwave system, James Benford, an authoritative person in the field of high-power microwave in the United States, pointed out four development directions of high-power microwave sources in the future: (1) Comprehensively reduce the size and weight of the system and increase the power consumption ratio ; (2) high repetition frequency work; (3) frequency can be tuned; (4) long life. In order to meet the development and application requirements of high-power microwave sources in the future, a practical high-power microwave source has been developed. The relativistic magnetron with the c...
