    • A microwave amplifier tube having a first and a second ring resonator of which the first serves as a driver resonator and the second serves as an output resonator. By means of a cathode system an electron beam rotating about the ring axis at the frequency of a control signal is generated. The electron beam is accelerated by a direct voltage and enters the second ring resonator which is tuned to the same frequency as the first resonator. The electron beam influences a high-frequency electromagnetic field in the second resonator and delivers a part of its energy to said second resonator. In order to facilitate equalization of the angular phase velocities in the two resonators, the ring resonators are provided above each other in the direction of the ring axis and the electron beam passes through the first and the second ring resonator parallel to the ring axis.

    • The velocity modulation microwave tube includes an electron gun for projecting a stream of electrons over an elongated beam path to a collector structure. An input circuit and an output circuit are disposed at the upstream and downstream ends, respectively, of the beam for applying microwave energy to be amplified to the tube and for extracting the amplified microwave energy from the beam. A penultimate resonator circuit, tuned for a mode of resonance at a frequency near the passband of the tube, is provided just upstream of the output circuit for bunching the current density of the beam passing into the output circuit. A harmonic floating resonator structure is disclosed along the beam path intermediate the input circuit and the penultimate resonator. The harmonic resonator is tuned for a mode of resonance approximately at a frequency corresponding to a harmonic higher than the first of the center frequency of the passband of the tube. The harmonic resonator serves as a prebuncher to bunching the electrons of the beam prior to their entering the final stage of bunching performed by the penultimate floating resonator. The combined action of the harmonic prebuncher resonator and the penultimate final buncher resonator is to substantially increase the radio frequency conversion efficiency of the tube.

    • An inductive output tetrode includes a cylindrical ceramic envelope within which is located an electron gun including a cathode and grid. An annular resonant input cavity into which a high frequency signal is coupled surrounds the envelope and is located adjacent the electron gun so as to provide a modulating electric field in the cathode-grid region to density modulate the electron beam. The input cavity is connected to two metal cylinders arranged immediately adjacent to the outside of the envelope. Metallic portions located within the envelope are co-extensive with cylinders with the material of the envelope 1 being located between them. These structures act as r.f. chokes to reduce high frequency losses from the input cavity. Tuning of the resonant cavity may be achieved by adjusting a tuning member which is at distance of quarter of a wavelength at the resonant frequency from the cathode-grid region.

    • A method for suppressing second and higher harmonic power generation in a klystron is described. The klystron includes a series of cavities that are connected to a series of connecting drift tubes, and one or more waveguide loads are placed on selected ones of the drift tubes or cavities, for reducing the second and higher harmonic power by causing it to be loaded out progressively, at predetermined discrete intervals. In the preferred embodiment, the inner diameter of the drift tubes is such that the cutoff frequency is above the fundamental operating frequency of the klystron, which will allow frequencies greater than the fundamental frequency, and particularly the second harmonic frequency, for example 22.848 GHz, to propagate. In one example, each of the four pre-selected drift tubes is loaded with two generally diametrically oppositely positioned waveguide loads. In another example, each of four drift tubes is loaded with three equidistally positioned waveguide loads. In yet another design, the drift tubes and/or cavities are loaded with encapsulated ceramic assemblies having lossy ceramic cylindrical segments that are inductively coupled to their corresponding drift tubes and/or cavities by means of inductive couplings. These segments can assume a variety of geometrical shapes.
    • 描述了一种用于抑制速调管中的二次和高次谐波发电的方法。 速调管包括连接到一系列连接漂移管的一系列空腔,并且一个或多个波导负载放置在选定的漂移管或空腔中,用于通过使其被加载来减小第二和更高次谐波功率 以预定的离散间隔逐渐排出。 在优选实施例中,漂移管的内径使得截止频率高于速调管的基本工作频率,其将允许大于基频的频率,特别是二次谐波频率,例如22.848GHz, 传播。 在一个示例中,四个预选漂移管中的每一个装载有两个大致直径相对定位的波导负载。 在另一示例中,四个漂移管中的每一个都装载有三个等距定位的波导负载。 在另一种设计中,漂移管和/或空腔装载有具有有损陶瓷圆柱形段的封装陶瓷组件,其通过电感耦合感应耦合到其相应的漂移管和/或空腔。 这些段可以呈现各种几何形状。
