Electron emission from grid is a serious problem for it limits the service time and destroys the working condition of the traveling wave tubes. After coating carbon films on the surface of the control grid by ion beam en- hanced deposition (IBED) in our laboratory
the electron emission from control grid was suppressed. One of the trav- eling wave tubes with control grid treated with coating carbon film already had a service time more than 1000 h. This technology has already been used in defense and aviation field successfully. The preparation and properties of two kinds of carbon films-diamond like carbon and graphite like carbon
their applications and mechanism for suppression of electron emission are presented in this paper.
