- H01J25/30—Reflex klystrons, i.e. tubes having one or more resonators, with a single reflection of the electron stream, and in which the stream is modulated mainly by velocity in the modulator zone in which the electron stream is perpendicular to the axis of the resonator or resonators and is radial or disc-like before reflection
