having only one cavity or other resonator, e.g. neutrode tubes

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons > Magnetrons, i.e. tubes with a magnet system producing an H-field crossing the E-field > with an electron space having a shape that does not prevent any electron from moving completely around the cathode or guide electrode > having only one cavity or other resonator, e.g. neutrode tubes

CPC:

Transit-time tubes, e.g. klystrons, travelling-wave tubes, magnetrons (details of transit-time tubes H01J23/00; particle accelerators H05H) > Magnetrons, i.e. tubes with a magnet system producing an H-field crossing the E-field (with travelling wave not moving completely around the electron space H01J25/42; functioning with plural reflection or with reversed cyclotron action H01J25/62, H01J25/64) > with an electron space having a shape that does not prevent any electron from moving completely around the cathode or guide electrode > having only one cavity or other resonator, e.g. neutrode tubes

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
