To satisfy the requirements for a pulsed space traveling-wave tube, including high efficiency, high reliability, and miniaturization, its thermal and mechanical performance must be optimized. In this paper, an electron gun is optimized using ANSYS software with double goal methods that take both thermal and mechanical factors into consideration. Experimental result shows that the heating power of...
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...
Low temperature sintered nano-silver paste becomes a potential alternative in green electrical packaging because of its higher thermal and electrical conductivity than conventional solders. It can be used for connected chips that require high temperature operation, such as high power LED and power electronics modules, etc. During service, alternating shear strain, even thermal fatigue failure will...
