Abstract

The invention belongs to the technical field of microwave sources in the high power microwave technology and particularly relates to a relativistic magnetron which makes an axially output microwave mode purer, makes a whole system more compact and has a circular TE11 output mode. In order to solve the problems that current axially output relativistic magnetrons need a purer single output mode and existing axially output relativistic magnetrons are not prone to meet the requirements of compactness, miniaturization and the like, the novel relativistic magnetron is put forward. The relativistic magnetron is composed of a coaxial input structure, a resonant cavity structure, an axial output transition section, a circular output waveguide and an external magnetic field system. Due to an improvement on a magnetron anode structure and the design of the axial output transition section, the circular output waveguide and the external magnetic field system, not only can the circular TE11 output mode which is purer be directly output axially, but also the whole system can be more compact and miniaturized.

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 a circular TE11 output mode that can make the axial output microwave mode 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 characte...
