Abstract : The patent describes a traveling wave tube having a control grid that backs and fills across the entire cathode emitting surface to form a delay line with the cathode. This delay line causes the electron beam to take on the helical pattern of a transverse wave. The traveling wave tube has a slow wave circuit which interacts with the transverse beam wave. Circuit means is provided for coupling signal energy to both the control grid and to the slow wave interaction circuit in a predetermined amplitude and phase relationship. The control grid is operated with DC cutoff bias.
