摘要： A magnetron characterized by a supporting cylinder, a field emission cathode, a slow wave structure, and a waveguide. The slow wave structure includes an anode block positioned coaxial with and surrounded by the field emission cathode. The anode block includes sixteen radially-projecting vane panels defining sixteen resonant cavities therebetween. Each of the resonant cavities may comprise a resonant channel portion positioned radially proximate to and axially coextensive with a center axis of the anode block. A void between the anode block and the field emission cathode, along with the resonant cavities, define an interaction region. The waveguide, comprising a cylinder characterized by an exterior layer surrounding an interior void, is capacitively coupled to the slow wave structure and configured to deliver radio frequency (RF) energy extracted from the interaction region by one (or, optionally, two) excitation rings mounted at a downstream end of the anode block.

摘要： An inductive output tube (IOT) provides improved efficiency and larger bandwidth. In one embodiment, an IOT is provided with an electron gun that generates an electron beam, a tube body, a collector for collecting the electron beam, and an extended-interaction output circuit. The electron beam travels through the tube body and the extended-interaction output circuit. The extended-interaction output circuit is located within the tube body. The extended-interaction output circuit comprises a short- circuited resonant structure. The extended-interaction output circuit is used for reducing undesired components of a radio frequency (RF) wave, increasing desired components of the RF wave, and slowing down the propagation of the RF wave. (That is the circuit increases the integral of the electric field along the path of the beam electrons while decreasing the stored energy associated with those fields.) The extended-interaction output circuit also provides the IOT with larger bandwidth operation. The collector may be a multi-stage depressed collector having voltages on the collector to result in a constant efficiency characteristic. The radio-frequency drive power to the tube is connected by means of a broadband impedance matching transformer, and the grid to cathode capacitance may be reduced by depressions in the surface of the cathode directly underneath the grid structure.

摘要： A printed circuit Traveling-Wave Tube (TWT) with a vacuum housing containing either a pair of identical meanderline slow-wave interaction circuits or a pair of multi-arm spiral slow-wave interaction circuits printed on two identical Photonic Band Gap crystal structures, and a gridded electron gun assembly. Printed on the two identical Photonic Band Gap crystal structures are electrical connections to connect the heater, cathode, grid and acceleration electrodes of the electron gun assembly to a power supply, RF input and output connectors surrounded by ground planes, a depressed collector, and a set of electrical connections to the depressed collector. Zig-zag metal spacers between the two identical Photonic Band Gap crystal structures are used to form the electron beam vacuum gap. Printed conducting metal strips on each side of the meanderline slow-wave interaction circuits are used for electrostatic focusing and to reduce beam edge effects of a sheet electron beam.

摘要： A traveling wave tube includes a glass or other insulating envelope having a plurality of substantially parallel glass rods supported therewithin which in turn support an electron gun, a collector and an intermediate slow wave structure. The slow wave structure itself provides electrostatic focussing of a central electron beam thereby eliminating the need for focussing magnetics and materially decreasing the cost of construction as well as enabling miniaturization. The slow wave structure advantageously includes cavities along the electron beam through which the r.f. energy is propagated, or a double, interleaved ring loop structure supported by dielectric fins within a ground plane cylinder disposed coaxially within the glass envelope.

摘要： An element with periodic structure for guiding electromagnetic waves propagating along a longitudinal axis of the structure at a speed below the velocity of light is disclosed. The structure includes a series of metal polar expansions aligned with the mentioned axis and forming a plurality of resonant metal cavities. The polar expansions have respective apertures aligned with each other so as to form a freeway for electron flow. First and second conductors are provided for cooperating with the polar expansions. The polar expansions each further respectively have first and second apertures for receiving first and second conductors that are preferably positioned diametrically opposed to each other with respect to the mentioned longitudinal axis. The first conductors are short circuited only to alternate ones of said polar expansions, and the second conductors are short circuited only to respective alternate ones of said polar expansions, such that each polar expansion is short circuited only to one of the first and second conductors.
