H01J25/10 - CPC Classification

Classification description:

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 Klystrons, i.e. tubes having two or more resonators, without reflection of the electron stream, and in which the stream is modulated mainly by velocity in the zone of the input resonator
