Microwave tubes for communication must have high reliability, high power, and a long life of 10 to 15 years. Cathode as the electric source module in microwave vacuum tubes, its reliability and life directly affect the tube's reliability and life. In this paper, electronic gun in short tubes are accelerated to evaluate the lifetime of one kind of microwave vacuum (such as traveling wave tube). In...
Influence of weld technology on reliability and life to cathode in vacuum tube was studied by requests of microwave tube. The quality of weld technology quite affects the emission capability of cathode. The mode of weld quite affects thermal efficiency of cathode in vacuum tube. Thermal efficiency of cathode can increase availably by changing the weld technology on the heat transfer path. Thermal...
