    摘要： A vacuum tube for handling an r.f. signal having a predetermined frequency range comprises a linear electron beam emitting cathode (136), a heater (166) and a non-electron emissive current modulating grid (138). The grid (138) is positioned from the cathode (136) by the distance an emitted electron from the cathode (136) can travel in a quarter cycle of the r.f. signal. Outer (202) and inner (204) coaxial metal tubes forming a resonant line of a signal coupler (143) are respectively connected to the grid (138) and cathode (136) so electrons passing through the grid (138) are in bundles in an interaction region (20) between an accelerating anode (18) and the grid (138). Ferrite tiles (42) absorb r.f. fields in the interaction region (20). In one embodiment a signal coupling loop (12) is between metal tubes (202,204) at an end of the tubes spaced 3λ/4 from the grid (138) and cathode (136). In a second embodiment the coupler (143) includes a low voltage coaxial line (110) having an inner conductor (112) connected to a first metal face (125), spaced from a second opposed metal (134) face by a solid dielectric (140). The coaxial outer conductor (114) is connected to a third metal face (128), spaced from a fourth opposed metal face (142) by the solid dielectric (140). The third (128) and fourth (142) faces surround the first (125) and second (134) faces. The first (115) and third (128) faces are at DC ground potential while the second (134) and fourth (142) faces are at high negative DC voltages. The second (134) and fourth (142) faces are respectively at common ends of interior (204) and exterior (202) coaxial metal tubes forming a λ/2 coupler (143). Other ends of the tubes (202,204) are connected to the cathode (136) and grid (138). Bias leads (190,194) for the grid (138) and cathode (136) are connected to the exterior (202) and interior (204) tubes at positions λ/4 from the grid (138) and cathode (136), while a heater lead (196) goes through the interior tube (204) at a position λ/4 from the grid (138) and cathode (136).

    摘要： La présente invention propose un convertisseur de mode de propagation guidée des ondes électromagnétiques, comprenant une structure de transition et des moyens de couplage entre cette structure et un guide d'onde apte à propager le mode résultant de la conversion de mode, et comprenant également des moyens de couplage entre la structure de transition et un guide d'ondes ou une source d'énergie électromagnétique hyperfréquence.
    Selon une caractéristique importante de l'invention, ladite structure de transition comprend l guides d'ondes, (g₁, g₂,... g l ), l étant un nombre entier supérieur à un, choisi en fonction du mode TE lm à convertir (m étant également un nombre entier supérieur ou égal à 1) ; ces l guides étant couplés à leurs deux extrémités, par des trous de couplage, respectivement à une source d'énergie électromagnétique hyperfréquence ou à un guide (G1) dans lequel se propage une onde TE lm de structure complexe, d'une part, et d'autre part à un guide d'ondes (G2) apte à propager le mode résultant de la conversion.
    Selon une autre caractéristique importante de l'invention, la structure de transition comprenant l guides d'onde est couplée directement sur la cavité de sortie d'un tube hyperfréquence ; et, selon une autre caractéristique, ledit tube hyperfréquence est un gyrotron.

    摘要： A klystron has a plurality of electron beam paths and plural damped disc-shaped cavities. The plurality of electron beam paths cut the cavities and the Klystron amplifier further comprises an annular input cavity and an annular output cavity disposed around the substantially circular external periphery of respective disc-shaped cavities, and in communication with it. The output cavity is arranged to receive RF power from the electron beams, wherein the cavities are arranged to support one of a single resonant rotating wave in a whispering-gallery mode, and a single resonant standing wave in a whispering-­gallery mode.

    摘要： An electron beam tube apparatus comprises a plurality of electron beam tubes (21, 22) having a common output cavity (25). Power is coupled to the common cavity from the resonant cavities (23, 24) of the beam tubes, and is then fed to an output line (29). This arrangement permits the outputs of two or more beam tubes to be combined in a compact arrangement with little rf power loss. Previously, the signals from the output lines of respective beam tubes were combined. The output line may be transmission line or waveguide. The means (26, 27, 28) for coupling signals between the cavities may comprise loops or irises, both of which may be selectively adjustable.
