in which the electron stream is in the axis of the resonator or resonators and is pencil-like before reflection

Full Title

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons > Tubes with electron stream modulated in velocity or density in a modulator zone and thereafter giving-up energy in an inducing zone, the zones being associated with one or more resonators > 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 in the axis of the resonator or resonators and is pencil-like before reflection
