Description

technical field [0001] The invention belongs to the technical field of microwave vacuum electronic components, and relates to the structure and manufacturing technology of electronic components in a traveling wave tube. More specifically, the invention relates to a collector needle of a traveling wave tube. In addition, the present invention also relates to its processing technology. Background technique [0002] A traveling wave tube is a power amplifier device that uses the interaction between a high-speed electron beam and a microwave signal to convert the kinetic energy of the electron beam into microwave energy. [0003] 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. Among other devices, traveling wave tubes can also be used in t...
