H01J2225/02 - 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
Sub-classes:
- H01J2225/025 » with an electron stream following a helical path 0
- H01J2225/04 » Tubes having one or more resonators, without reflection of the electron stream, and in which the modulation produced in the modulator zone is mainly density modulation e.g. Heaff tube 3
- H01J2225/06 » Tubes having only one resonator, without reflection of the electron stream, and in which the modulation produced in the modulator zone is mainly velocity modulation, e.g. Lüdi-Klystron 0
- H01J2225/10 » 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 2
- H01J2225/22 » 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 0
- H01J2225/32 » Tubes with plural reflection, e.g. Coeterier tube 0
