Cerenkov microwave generator with frequency converted between C waveband and X waveband

Abstract

The invention discloses a Cerenkov microwave generator with the frequency converted between a C waveband and an X waveband. A cathode base, a cathode, an anode outer cylinder, a cut-off neck, a C-waveband slow wave structure, a drift section, an X-waveband slow wave structure and a microwave output port are arranged in a solenoid magnetic field, the whole structure is rotationally symmetrical relative to the central axis, and high beam-wave action efficiency can be achieved for the two wavebands. By designing the length and radius of the drift section, when the drift section and the front andrear slow-wave blades are distributed in a stepped mode, peak values with the optimal effect can be generated through the beam-wave effects of the two wave bands respectively.

Description

technical field [0001] The invention relates to the field of microwave sources, in particular to a Cerenkov microwave generator whose frequency is converted between C and X bands. Background technique [0002] High-power microwave is a kind of strong electromagnetic pulse. It is usually defined as an electromagnetic wave with a power greater than 100MW and a frequency between 0.1-100GHz. It has the characteristics of high power and directional radiation. It is used in civil technology and national defense military fields, such as plasma fusion , high-energy particle accelerators, ultra-long-range radars, directed energy weapons, etc., have broad application prospects. In the 1970s, with the development of pulse power technology, relativistic electronics and plasma physics, the combination of traditional electric vacuum devices and high-current relativistic electron beams formed a relativistic electric vacuum device capable of generating high-power microwaves, that is, high-p...

Problems solved by technology

[0006] The adjustment methods of existing frequency modulation devices are complicated. Under the condition of maintaining high vacuum, it is often necessary to adjust multiple structural parameters (usually more than 2); the adjustment bandwidth of the radiation frequency is often very narrow, and most of them are fine-tuned within a certain band
