    摘要： 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.

    摘要： 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.

    摘要： A detector system for performing at least one of transmitting and receiving electromagnetic radiation at a low-terahertz frequency. The detection of electromagnetic radiation at low-terahertz frequencies can be useful in the detection of various chemicals. Preferably a detector includes a microresonant structure that is caused to resonate by electromagnetic radiation at a low-terahertz frequency. The resonance is detected by detecting an altered path of a charged particle beam.

    摘要： A klystron with widened instantaneous passband comprises a succession of cavities separated by drift tubes, divided into three blocks. The first block comprises all that is upline from a first central cavity, the third block comprises all that is downline from a second central cavity and the second block comprises the central cavities. In each block, the sum of the lengths of the drift tubes is equal to: H+(T.times.180.degree.). H is a quantity ranging from 45 to 135 plasma degrees and T is an integer greater than or equal to zero. In at least one of the blocks, T is greater than or equal to one and the length of at least one tube of this block is greater than or equal to 135 plasma degrees. The disclosed device can be applied to wideband klystrons.

    摘要： A klystron oscillator has an input cavity resonant in a TM.sub.010 mode and a larger output cavity resonant in a TM.sub.OnO mode where n is an integer greater than 1, preferably equal to 2. The input cavity, with re-entrant bosses defining a buncher gap, projects into the output cavity to form one of two re-entrant bosses thereof defining a catcher gap.
