    摘要: L'invention concerne les tubes hyperfréquences à vide, et plus particulièrement les tubes à ondes progressives.
    Le tube comporte un canon à électrons capable d'émettre un faisceau d'électrons dans l'axe d'un fourreau cylindrique métallique (10) qui s'étend entre une entrée (24) de signal hyperfréquence à amplifier et une sortie (26) de signal amplifié. L'entrée de signal comprend une plaque diélectrique (40) formant fenêtre de transmission d'énergie hyperfréquence, cette plaque étant encastrée et brasée dans une ouverture ménagée dans la paroi du fourreau, la plaque ne débordant pas au-delà du périmètre extérieur du fourreau cylindrique et fermant de manière étanche au vide la dite ouverture. Une embase (34) de réception de câble coaxial est soudée sur le fourreau et une connexion est faite entre l'âme du câble coaxial et un conducteur d'entrée (42) formé sur la fenêtre (40). Avec une telle fenêtre, on peut enfiler des aimants (18) cylindriques d'une seule pièce sur le fourreau, après brasure de la fenêtre. Les aimants résistent à la température d'étuvage du tube et l'étuvage peut être fait après soudure du canon à électrons et du collecteur du tube.

    摘要: Axially symmetric magnetic fields are provided about the longitudinal axis of each beam of a multi-beam electron beam device (MBEBD). A flux equalizer assembly is disposed between the cathodes and the anodes and near the cathodes of a (MBEBD). The assembly includes a ferromagnetic flux plate completely contained within the magnetic focusing circuit of the (MBEBD). The flux plate includes apertures for each beam of the (MBEBD). A flux equalization gap or gaps are disposed in the flux plate to provide a perturbation in the magnetic field in the flux plate which counters the asymmetry induced by the off-axis position of the beam. The gaps (MBEBD) have the effect of producing a locally continuously varying reluctance that locally counters the magnetic field asymmetry. The flux equalizer assembly prevents or substantially reduces beam twist and maintains all of the electron beams of the (MBEBD) as linear beams.

    摘要: The present invention provides a multi-beam klystron apparatus (11). In the above-described multi-beam klystron apparatus, the magnetic field generating element (52) of the electron-gun-unit-side magnetic field generating unit (41) is disposed around the electron gun unit (18), and a plurality of magnetic gaps (54, 55) are provided in the inner peripheral surface of the magnetic pole (53), which covers the magnetic field generating element, in the direction of travel of the electron beams. Therefore, lines of magnetic force, which are parallel to the center axis of the radio-frequency interaction unit (19), can be generated. Thus, even the electron beam, which is generated from the location apart from the center axis of the electron gun unit, can be guided to the radio-frequency interaction unit in the same manner as in the location at the canter axis of the electron gun unit.

    摘要: A multi-beam klystron apparatus (11) is disclosed. A radio-frequency interaction unit pole piece (52) is arranged between a main magnetic field generator (40) and an output-side magnetic field generator (44). The magnetic circuit formed in the neighborhood of an output cavity (36) of a radio-frequency interaction unit (19) is separated from the magnetic circuit of the main magnetic field generator (40) by the radio-frequency interaction unit pole piece (52). The output-side magnetic field generator (44) increases the axial magnetic flux density in the neighborhood of the output cavity (36) without curving the electron beams and thus prevents the spread of the electron beams in the neighborhood of the output cavity (36).
