Abstract: In an electron gun for use in a TWT, klystron, linear accelerator or other electron device, an electron gun header assembly and an input body assembly are coupled using a flexible bellows that allows the distance between the cathode and anode to be varied. As such, the perveance of the electron gun can be tuned, and the cathode magnetic field optimized for efficient operation. In addition, an external magnetic shield is adapted to be translated along the axial dimension of the electron gun to further optimize the cathode magnetic field and focusing characteristics to achieve improved electron gun performance.

Abstract: The invention provides an apparatus and method of switching more than one bias voltage within an electron beam tube in order to achieve electron beam cutoff. The invention is particularly useful for high-perveance electron tubes in which a large change in focus-electrode-to-cathode or anode-cathode voltage might otherwise be needed to achieve cutoff. In one embodiment of the invention, the cathode and anode bias voltages are both switched by magnitudes well within the capabilities of standard high-voltage switches to achieve beam cutoff.

Abstract: An electron gun comprises a shell having distal and proximal ends, a cathode structure disposed within the shell and having an electron emitting surface, an anode physically coupled to the shell at the distal end and spaced a fixed distance from the emitting surface, and a plurality of leads adapted to apply a voltage to the cathode structure with respect to the anode sufficient to cause emission of the electrons from the emitting surface. The anode has an aperture for passage therethrough of the beam of electrons emitted by the emitting surface. A first insulator is disposed within the shell proximal to the cathode structure. The first insulator has plural apertures having respective sizes in relation to corresponding ones of the plurality of leads such that the plurality of leads pass therethrough without contacting the first insulator. The first insulator provides stand-off for the voltage between the anode and cathode. A second insulator is disposed with the shell proximal from the first insulator.

The collector provides efficient heat transfer from the while reducing stresses on collector components caused by thermal cycling and comprises a heat sink having a cavity providing interior vacuum walls for the collector a segmented ceramic insulator disposed inside the cavity, and an electrode disposed inside and against the insulator. The insulator comprises sectors separated from one another by gaps, and may be notched in its outer surface for high-voltage stand-off from the sink. The electrode is preferably not brazed/soldered to the insulator. A stage of the electrode may be probeless and comprise a depression. A molybdenum-fabricated heat sink and stage assembly utilizes an insulator constructed from beryllium oxide, aluminum nitride, or alumina; alternatively, a copper assembly, uses an aluminum nitride insulator.

Abstract: A high power switching apparatus comprises an annular cathode having a surface capable of emitting a hollow electron beam therefrom and an anode cavity spaced from said cathode. The cavity has an annular opening smaller in dimension than a corresponding internal dimension that defines the cavity to provide a Faraday cage collector of the hollow electron beam. A control electrode, disposed between the cathode and the anode cavity in a non-intercepting position relative to the hollow electron beam, provides a controlling electric field region for modulation of the hollow electron beam. Arc suppressing electrodes, at approximately the same potential as the cathode, are disposed between the control electrode and the anode. An intermediate high voltage electrode, disposed between the arc suppressing electrodes and the anode cavity in a non-intercepting position relative to the hollow electron beam, provides a controlling electric field region for channeling of the hollow electron beam.
