Abstract

The invention provides a lateral output device for a wave gyro traveling wave tube, and belongs to the millimeter wave source technical field of the high-power millimeter wave technology, particularly a lateral output device for a wave gyro traveling wave tube, wherein a Gaussian beam can be directly outputted. In the prior art, a wave gyro traveling wave tube must be externally connected with a waveguide mode converter. In order to overcome the above defect in the prior art, the invention provides a novel output device for a wave gyro traveling wave tube. The output device comprises a transition waveguide section, a 90-degree waveguide turning section and a circular waveguide radiator. According to the technical scheme of the invention, a high-purity Gaussian beam can be laterally and directly outputted within a broadband range without any functional device, such as an external mode converter, an elbow or the like. Therefore, the complexity of a high-power millimeter wave application system is greatly reduced.

Description

technical field [0001] The invention belongs to the power source technology in the high-power millimeter wave technology, and in particular relates to a lateral output device of a convolved traveling wave tube capable of directly outputting Gaussian beams. Background technique [0002] The gyrotron is a high-power broadband millimeter-wave amplifier with the characteristics of broadband, high power, high gain and high efficiency. It has a wide range of application markets in communications, radar, precision guidance and material processing. In order to reduce the working loss of the device and improve the efficiency of injection wave interaction, the circular waveguide TE 0,n mode as a working mode. Compared with other modes, TE 0,1 The mode has lower transmission loss and is a typical output mode of the gyro TWT. [0003] The output device is a key component of the gyro TWT, which has a huge impact on the output power, mode purity and overall tube efficiency. In order t...
