摘要： An electron tube having a cathode and an anode with the anode subtantially surrounding the cathode and providing an electron-interaction space therebetween for providing a magnetic field having a substantial component oriented in the axial direction traversing this interaction space. The cathode structure is of reduced axial direction dimension for permitting the length of the magnetic field component to be minimized. The electron tube includes a substantial tubular cathode and a support means that is axially oriented and that is disposed adjacent to the cathode and is spaced away from the cathode substantially throughout its axial length. This support means is attached at one end to one end of the cathode and at the other end is supported at a vocation in the electron tube.

摘要： A resonant-cavity type electronic tube having mechanically-operable tuning vanes associated with its resonant-cavity structure and disposed within an evacuable envelope. A support member is provided within the envelope for adjusting the tuning vanes relative to the resonant-cavity structure, so as to tune the frequency of resonance of the structure step-wise in accordance with a predetermined program. The tuning is carried out with a step motor, having a stator and armature with the envelope having a portion extending between the stator and armature for enclosing the armature within the evacuable space containing the tuning vanes and the resonant cavity structure. The armature is coupled to the tuning vanes for altering the position thereof relative to the resonant-cavity structure in fixed relation to the displacement of the armature relative to the stator. Electrical signals are coupled to the stator for establishing a programmable series of displacements of the armature relative to the stator.
