Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only for facilitating the understanding of the present invention, and do not have any limiting effect on it.

[0025] A dual-mode cyclotron traveling wave tube amplifier of the present invention has a two-section structure, a linear amplification section and a nonlinear amplification section. The linear amplification section provides high gain to the amplifier, and the nonlinear amplification section provides high power.

[0026] The first section is a linear amplification section, which uses a loss-loaded metal waveguide and works in a low-order mode. The metal waveguide is usually a circular waveguide, and the inner wall of the waveguide is coated with a loss material or loaded with a layer of loss ceramics to form a distributed loss. Under proper loss conditions, the interacting electron beam of the amplif...

Abstract

The invention discloses a dual-mode gyrotron traveling wave tube amplifier, and relates to the technology of a microwave source device. The dual-mode gyrotron traveling wave tube amplifier has two-section structure, wherein the first section is a linear amplification section which adopts loss-loading metal waveguide and works at the low step mode; and the second section is a nonlinear amplification section which adopts smooth metal waveguide works at the high step mode; the linear amplification section provides high gain for the amplifier; and the nonlinear amplification section provides high power. The nonlinear amplification section works at the high step mode, thus having higher waveguide transverse size and stability threshold current. The dual-mode gyrotron traveling wave tube amplifier solves the problems of low working current and poor stability of a single-mode amplifier, and has higher output power and more superior stability, thus being a high-power millimeter wave source with good development potential and having development prospect in the important national defense fields such as high resolution long-range radar and the like in China.

Description

technical field [0001] The invention relates to the technical field of microwave source devices, and relates to a cyclotron traveling wave tube amplifier working in multiple interaction modes. Background technique [0002] In the late 1950s, the principle of electron cyclomaser interaction was discovered, and high-energy microwave sources based on this principle have been studied in depth both theoretically and experimentally. These high-energy microwave sources are used in today's radar communications, directed energy weapons, High gradient accelerators and other aspects have been widely used. A gyrotron traveling wave tube amplifier is an amplifier based on the principle of an electronic gyrotron maser. The device has unique broadband and high power characteristics, which make it the preferred microwave source for the development of next-generation high-resolution imaging radar. After nearly half a century of development, this type of device is still seriously affected b...
