Abstract: A coupled cavity circuit for a microwave electron tube comprises at least two resonant cavities adjacent to each other. An electron beam tunnel passes through the coupled cavity circuit to allow a beam of electrons to pass through and interact with the electromagnetic energy in the cavities. An iris connecting the adjacent cavities allows electromagnetic energy to flow from one cavity to the next. The iris is generally symmetrical about a perpendicular axis of the electron beam tunnel with the iris having flared ends and a central portion connecting the flared ends. The iris shape causes the iris mode passband to be lower in frequency than the cavity mode passband while still providing broadband frequency response.

Abstract: A focusing system for an electron beam within an RF amplification tube is provided. The focusing system comprises a plurality of magnetic polepieces each having a centrally disposed aperture, and a plurality of electrically conductive non-magnetic plates alternatingly and integrally provided with the polepieces, the non-magnetic plates each having a centrally disposed aperture. The apertures of the polepieces are aligned with the apertures of the non-magnetic plates to provide a beam tunnel through which the electron beam travels. At least one permanent magnet is coupled to the polepieces, the magnet having magnetic flux which flows through the magnetic polepieces to provide an axial magnetic field within the beam tunnel. The diameter of the beam tunnel is selected to be greater than a separation distance between adjacent ones of said polepieces, and the axial magnetic field varies substantially across a cross section of the beam tunnel. The axial magnetic field has a greatest RMS value at an outermost portion of the beam tunnel.

Abstract: A coupled cavity circuit for a microwave electron tube comprises at least two resonant cavities adjacent to each other. An electron beam tunnel passes through the coupled cavity circuit to allow a beam of electrons to pass through and interact with the electromagnetic energy in the cavities. An iris connecting the adjacent cavities allows electromagnetic energy to flow from one cavity to the next. The iris is shaped to cause the iris mode passband to be lower in frequency than the cavity mode passband while still providing broadband frequency response. In addition, the present coupled cavity circuit operates on an electron beam to interact with the third space harmonic of the second passband (the cavity passband) of the electromagnetic signal. Preferably, this interaction occurs on the second passband as this operational design provides output with higher frequencies without decreasing the cavity size. Furthermore, this operational design provides more frequencies with no increase to the iris size. This results in allowing higher power to be provided to the circuit without thermal degradation of the circuit. Also, because the interaction occurs on the third space harmonic of the second passband, the present operational design results in providing flatter frequency responses.

Abstract: An integral polepiece RF amplification tube for amplifying a millimeter wave RF signal is provided which has a laminate structure comprising a plurality of magnetic and non-magnetic conductive plates which are alternatingly and integrally formed together. The tube has substantially planar surfaces, which permit the attachment of a heat sink thereto. The non-magnetic plates each have a slot which provides a resonant cavity, and a portion of the magnetic plates have a notch which couples the cavities. A magnetic field induced into the tube provides focusing to an electron beam projected through a tunnel which passes through each of the cavities. The amplification tube can be configured for use as a coupled cavity traveling wave tube or a klystron.

Abstract: An electron collector is provided for collecting spent electrons generated by a charged particle device after passage though an interaction region of a RF circuit. The collector has a centerline and comprises an outer structure which is coupled to the RF circuit. An inner structure is within the outer structure, and receives the spent electrons. A negative voltage is applied to the inner structure, which forms an electric field between the inner and outer structures. A plurality of thermally conductive and electrically insulative standoff assemblies extend between the outer and inner structures. Each of the assemblies comprise a ceramic planar member centered within outer walls providing a double-ended cup shape, and conductive plugs which adjoin each side of the planar member with the respective one of the inner and outer structures. An axis of symmetry of the assemblies lies perpendicular to a radial vector extending from the centerline, and lies parallel to the electric field vector. Since the conductive plugs are partially surrounded by the outer walls, a relatively long surface voltage breakdown path is provided between the plugs, while the thermal path through the planar member is relatively short.

Abstract: An electron beam focusing system is provided within a microwave amplification tube formed from a plurality of magnetic polepieces interposed by non-magnetic spacers. The tube has an axially disposed beam tunnel which permits projection of the electron beam therethrough. A magnetic field is induced in the tube having lines of flux which flow through the polepieces along a magnetic axis. Heat formed within the circuit flows through the spacers to an external planar surface along a thermal axis, which is non-coincident with said magnetic axis. In an alternative embodiment, a plurality of the tubes can be combined into a common system for focusing a plurality of electron beams. The tubes within the common system share heat sinks which attach to the planar surfaces.
