    Abstract: An extended interaction output circuit interacts with a modulated electron beam and outputs RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities each having a gap permitting the traveling therethrough of the modulated electron beam. A first pair of the linearly disposed cavities is coupled by a single side cavity, a second pair of the linearly disposed cavities is coupled by a pair of side cavities radially disposed 180 degrees apart, and a third pair of the linearly disposed cavities is coupled by three side cavities radially disposed 120 degrees apart. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. RF energy is extracted from the fourth cavity through four waveguide sections that are radially disposed 90 degrees apart.

    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 extended interaction output circuit is provided for interacting with a modulated electron beam and for outputting RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities having an axially extending beam tunnel to permit the traveling therethrough of the modulated electron beam as well as to couple electromagnetic energy between the successive cavities. Each of the cavities is separated by an annular disk having a hole providing the axial beam tunnel. The hole diameters increase in steps so that the impedance of the successive cavities decreases along the axial extent of the circuit. The diameter of the successive cavities is also increased as the associated width is decreased to maintain the same mid-band resonant frequency. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. The gap-to-gap distance between successive cavities is selected to provide a 90 degree phase shift of the beam in order to maintain synchronous operation between the beam and the wave at the mid band frequency.

    Abstract: According to one embodiment, a klystron device includes a klystron body and a focusing magnetic field device. The klystron body has an electron gun section, a collector section, a plurality of cavity resonators, and a plurality of drift tubes. The cavity resonators have nose sections that face each other in an axial direction and form a gap section that is connected to the drift tubes. At least one of the cavity resonators has an electric field correction section in a part of the nose section that makes a space of the gap section different with respect to a space between the nose sections.

    Abstract: Technology is described for vacuum electron device (e.g., sheet beam klystron) that includes a hollow tube structure. In one example, the hollow tube structure includes at least three resonant cavities and at least two drift tube sections. Each resonant cavity includes a cavity width along a major axis and a cavity height along a minor axis. Each drift tube section includes a drift tube section width and a drift tube section height, and the cavity height is greater than the drift tube section height. A first drift tube section is disposed between a first resonant cavity and a second resonant cavity. A second drift tube section is disposed between the second resonant cavity and a third resonant cavity. A drift tube section width of the first drift tube section is substantially different from a drift tube section width of the second drift tube section.

    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.
