Electron gun is the foremost parts of twt, it can produce electron beam with a certain shape and current, in order to guarantee the reliability and security of work, it ’ s design have to meet to the requirement not only of electric parameter, but also all kinds of subsidiary characteristics such as filament pyrogenation efficiency, warm up time, shape size, pole space capacitance and the ability to be able to bear the press and all kinds of rigorous run conditions such as high temperature, high humidity, low air pressure, strong vibration and great strike
由於行波管的大功率和高頻率等特性,目前還沒有任何其他的器件可以代替。行波管是應用高頻電磁場與電子注進行互作用的機理進行工作的,而電子槍是行波管中產生電子注並使它成型的基本部件,電子槍的結構設計決定了槍體自身必須具有良好的抗振可靠性,否則結構發生共振或振動位移過量,就會導致行波管的失效。因此對行波管電子槍的研究具有非常重要的意義。 -
