Traveling wave tube (TWT) is a type of microwave vacuum electronic component. TWT often works under harsh mechanical environment stress, such as vibration, shock. The stress leads to the open circuit of filament in heater, which results in the change of inner structure and electric performances, even failure. This paper introduced a failure case of TWT in use. Failure mode and failure mechanism of filament in heater of a typical TWT was analyzed in this paper.
