H01J2225/22 - CPC Classification

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

• H01J2225/24 » in which the electron stream is in the axis of the resonator or resonators and is pencil-like before reflection 0
• H01J2225/26 » in which the electron stream is coaxial with the axis of the resonator or resonators and is tube-like before reflection 0
• H01J2225/28 » in which the electron stream is perpendicular to the axis of the resonator or resonators and is pencil-like before reflection 0
• H01J2225/30 » in which the electron stream is perpendicular to the axis of the resonator or resonators and is radial or disc-like before reflection 0
