Tubes with plural reflection, e.g. Coeterier tube

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

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 > Tubes with plural reflection, e.g. Coeterier tube

CPC:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons (details of transit-time tubes H01J23/00; particle accelerators H05H) > 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 > Tubes with plural reflection, e.g. Coeterier tube
