摘要： In order to bring a high power vacuum tube to full power in a few seconds, it is necessary to heat the cathode quickly to 1100°C. In large tubes, prior art structures cannot be simply enlarged. A novel cathode structure (10) in which the heater element (14) is anisotropic pyrolytic graphite coated with anisotropic pyrolytic boron nitride for insulation and then sintered to the cathode avoids these problems.

摘要： An electron-emitting cathode (6) consists of an electricaly conducting emitter layer (7) attached to a side wall (2) and a gate (9) which is fixed at a mall distance inside a concave emitter surface of the emitter layer (7). The cathode (6) surrounds a reaction area (3) containing a cylindrical grid-like anode (5) and a central ion collector (4) which consists of a straight axial filament. An ion collector current (I IC ) reflecting the densitiy of the gas in the reaction region (3) is measured by a current meter (11) while a gate voltage (Vc) is kept between the ground voltage of the emitter layer (7) and a higher anode voltage (V A ) and is regulated in such a way that an anode current (T A ) is kept constant. The emitter layer (7) may comprise an array of metal, e.g., nickel or molybdenum tips or consist essentially of a semiconductor material like silicon, preferably coated by, e.g., carbide, diamond-like carbon or molybdenum, or of carbon nanotubes or it may be a roughened surface portion of the side wall surface. The gate (9) may be a grid or it may be made up of patches of metal film covering spacers distributed over the emitter area or a metal film covering an electron permeable layer placed on the emitter surface.

摘要： A gridded electron tube suitable for generating high power at high frequency, has a cathode surface composed of a set of parallel emitting strips separated by non-emitting strips. Massive grid bars are aligned over the non-emitting strips, thereby reducing grid current interception and providing thermal dissipation. Attached to the side of the grid bars facing the cathode is an array of closely spaced fine wires which increase the electric field due to the grid at the emitting surface, and decrease the penetration of field due to the anode, thereby increasing the transconductance and amplification factor, decreasing the transit time of electrons, and improving the uniformity of emission current density.
