Description

technical field [0001] The invention relates to a processing technology of a cathode molybdenum cylinder of a multi-beam traveling wave tube. Background technique [0002] The traveling wave tube is a power amplifier device that converts the kinetic energy of the electron beam into microwave energy by using the interaction between the high-speed electron beam and the microwave signal. It is a microwave tube that realizes the amplification function by continuously modulating the speed of the electron beam. The application range of traveling wave tubes is very wide, and almost all satellite communications use traveling wave tubes as final amplifiers. In most radar systems, one or several traveling wave tubes are used as high-power amplifiers for generating high-frequency transmission pulses. In addition, traveling wave tubes can also be used in some high-power amplifiers, such as the excitation stage of cross-field amplifiers, in other devices. According to the slow wave str...
