H01J25/587 - CPC Classification

Classification description:

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 a number of resonators; having a composite resonator, e.g. a helix Multi-cavity magnetrons
