摘要： A two-dimensional circuit for a traveling-wave tube for millimeter and sub-millimeter electromagnetic waves synchronously interacts with an electron beam in a vacuum electronic microwave amplifier or oscillator. The circuit is a solid body having a length along the tube axis. The solid body has an electrically conductive top section and an electrically conductive bottom section. The top section is configured with a plurality of vertical vanes having a width and height and configured parallel to each other. The bottom section is similarly configured such that when the circuit is viewed in cross section along the length, the vanes on the bottom section are staggered with respect to the vanes on the top section. The top section and the bottom section are separated from each other to define a tunnel through the solid body along the length.

摘要： A magnet configuration for a power microwave tube with a resonant cavity comprises a permanent magnet (110) with an axis-aligned through-bore (135) of sufficient size to contain the resonant cavity. The permanent magnet has an inner chamber (140) that is centered on the axis (130) with opposite magnet poles aligned along the axis. The magnet configuration further comprises an electromagnet coil (120) fitting in the chamber and encircling the axis such that the coil produces a magnetic field that reinforces the magnetic field from the permanent magnet. An optional protrusion (125) spanning the through-bore narrows an air gap between the poles. The method provides a magnetic field in a power microwave generator by combining a permanent magnet with an electromagnet in accordance with the magnet configuration and energizes the electromagnetic coil, which may be by pulsing the coil current.

Each filter comprises, in one embodiment, a main coaxial cavity tuned to a distinct center frequency, a first simple isolation cavity for coupling rf energy between the input waveguide and the main cavity, and at least one second simple isolation cavity for coupling energy between the main cavity and the tapered interaction waveguide. This coupler is compatible both in bandwidth and geometry with the tapered interaction waveguide.

摘要： A traveling-wave device for amplification of RF signals at microwave frequencies, primarily from UHF to submillimeter wavelengths, comprised primarily of broad-coupled parallel striplines of which one is a cathode stripline and the other a non-intercepting gate stripline disposed between conducting plates. Electrons are emitted from the cathode stripline and accelerated by DC electric fields through the non-intercepting gate stripline on which the microwave signal is propagating in a transmission mode which has reversed directions of the microwave electric field on each side of the gate stripline. The odd mode component of the microwave electric field, between the gate stripline and cathode stripline, serves to modulate and/or stimulate electron emission from the cathode stripline and the reversed direction of the microwave electric field between the gate stripline and the conducting plate decelerates the electrons to add their energy to the propagating wave for amplification. Positive feedback, due to the coupling of the growing RF propagating wave of the stripline system to the odd mode modulating signal, gives the amplifier large and continuous exponential gain.

摘要： A cyclotron maser microwave amplifier or oscillator which utilizes non-relativistic electrons (or other charged particles) in cyclotron motion and a spatially nonlinear electrostatic field. The term "spatially nonlinear electrostatic field" encompasses static electric fields whose magnitude can be described mathematically as varying in a nonlinear manner as a function of position in one or more directions. Completely non-relativistic electrons of very low energy may be used in principle for which phase bunching will occur due to the nonlinear motions (induced by the electrostatic field) resulting in stimulated emission of cyclotron radiation for use in the amplifier or oscillator. This is in complete contrast to the relativistic cyclotron maser (Hirschfield, U.S. Pat. No. 3,398,376) which required the electrons to be acting under the relativistic effect of the electron mass (and hence cyclotron frequency) being a function of its energy to produce the necessary phase bunching and resulting stimulated emission. This new means of cyclotron maser action, in principle, is induced by a variety of spatially nonlinear electrostatic fields.

摘要： A gas ionization type vacuum gauge for testing the internal vacuum levels to below 10.sup.-6 torr is disclosed which uses a multipactor discharge means as the source for the electron current used to ionize residual gas molecules. The invention comprises an RF field enhancing cavity which can be constructed of high-vacuum-compatible materials, able to withstand bake-out microwave temperatures and a negatively biased ion collection wave, wire, or grid. A simple ceramic RF feed-through permits simple and noninvasive pressure measurements. The device can be made much smaller than conventional gauges.
