摘要:
A high voltage, high current vacuum integrated circuit includes a common vacuum enclosure that includes at least two cold-cathode field emission electron tubes, and contains at least one internal vacuum pumping means, at least one exhaust tubulation, vacuum-sealed electrically-insulated feedthroughs, and internal electrical insulation. The cold-cathode field emission electron tubes are configured to operate at high voltage and high current and interconnected with each other to implement a circuit function.

摘要:
The present invention relates to an electronic tube with cylindrical electrodes. In tubes of this kind, where the cathode generally consisting of a wire mesh 1, the space located within same is tightly coupled with the other inter-electrode spaces of the tube. The invention, in order to avert parasitic resonances at the harmonics closest to the operating frequency, which can occur in said space in operation, provides for the arrangement in said space of a certain number of metal sleeves 8, 9 and 10 coaxial with the electrodes, constituting low-inductance coaxial line sections.Application to high-power, short-wave (20 MHz) triodes for transmitting applications.
摘要:
A long-life discharge tube, which may be miniaturized and still hold-off high voltages and which may be operated in conditions which may include high pressure gas atmospheres and high temperatures surrounding the tube, including gas impervious ceramic and metal wall components over all exterior portions of the tube and a generally cup-shape anode electrode separted from an annular triggered cathode which is positioned at least partially within the walls of the anode.
