Abstract
This paper has described the reliability of the grid-controlled traveling wave tube (TWT) which caused by the evaporation of the cathode. If the cathode evaporates a lot, the TWT would damage in two cases, such as spark and grid-emission. The analysis of these two problems and the methods we usually used have been shown here.
