    摘要： The present invention relates to a bidirectional high-voltage cold-cathode field-emission vacuum electron tube, comprising:
    a) a cylindrical inner electrode encircled by a first cylindrical grid, in turn encircled by a second cylindrical grid, in turn encircled by a cylindrical outer electrode; the inner and outer electrodes and the first and second grids sharing a common main axis;
    b) the inner and outer cylindrical electrodes respectively functioning bidirectionally, as either a field emission cathode or an anode, depending on the instantaneous polarity of the signal applied across said electrodes;
    c) the radial spacing from the inner electrode to the first grid is such as to create therebetween a circular waveguide supporting the transverse electromagnetic mode; and the spacing between the second grid and the outer electrode is such as to create therebetween a circular waveguide supporting the transverse electromagnetic mode; and
    d) the radial spacing between the first grid and the second grid is sufficient to prevent flashover between the first and second grids at an intended operating voltage.

    摘要： A high-speed current shunt comprises a flat conductive metal strap having a first and a second electrode at each end of said strap for connection to an external circuit for receiving current through the strap, said strap having a defined current-measuring region extending from a first linear position to a second linear position along the length of the strap. The high-speed current shunt also comprises a tapered parallel-plate transmission-line impedance-matching transformer, comprising first and second plates tapered in shape and having a wide end and a narrow end, relative to one another, each tapered plate having a length approximately 10 times that of width of said metal strap, said first plate being attached at its wide end to said first linear position of the defined measuring region by a solder and said second plate being attached at its wide end to said second linear position of the defined measuring region by a solder, and a coaxial cable with a center conductor being attached by a solder to the narrow end of the first plate, and a shield being attached by a solder to the narrow end of the second plate.

    摘要： High voltage high current regulator circuit for regulating current is interposed between first and second terminals connected to an external circuit and comprises at least one main-current carrying cold-cathode field emission electron tube conducting current between the first and second terminals. First and second grid-control cold-cathode field emission electron tubes provide control signals for first and second grids of the at least one main-current carrying cold-cathode field emission electron tube for positive and negative excursions of voltage on the first and second terminals, respectively. The current regulator circuit may be accompanied by a voltage-clamping circuit that includes at least one cold-cathode field emission electron tube. At least two cold- cathode field emission electron tubes, configured to operate at high voltage and high current, are preferably contained within a single vacuum enclosure and are interconnected to provide a circuit function, so as to form a high voltage high current vacuum integrated circuit.
