Introduced: September 1968

Titles differ between systems:

IPC: in which a standing wave or a considerable part thereof is produced along an electrode, e.g. Clavier tube

CPC: in which a standing wave or a considerable part thereof is produced along an electrode, e.g. Clavier tube (with resonator having distributed inductance and capacitance H01J25/70)

Full titles differ between systems:

IPC:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons > Tubes specially designed to act as oscillator with positive grid and retarding field, e.g. for Barkhausen-Kurz oscillators > in which a standing wave or a considerable part thereof is produced along an electrode, e.g. Clavier tube

CPC:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons (details of transit-time tubes H01J23/00; particle accelerators H05H) > Tubes specially designed to act as oscillator with positive grid and retarding field, e.g. for Barkhausen-Kurz oscillators (with secondary emission H01J25/76) > in which a standing wave or a considerable part thereof is produced along an electrode, e.g. Clavier tube (with resonator having distributed inductance and capacitance H01J25/70)
