Definitions

  • the invention relates to a traveling wave tube (TOP) with coupled cavities, the beam focusing of which is ensured by a system of permanent magnets of the "PPM” type, namely "Periodic Permanent Magnet”.
  • Such a focusing system known as "alternating permanent magnets” consists, as known in the art, of rings tight against each other around the axis of the tube, alternately consisting of magnets and pole pieces.
  • the polar masses made of soft iron, or any other material with low reluctance are incorporated into the walls of the cavities, made of copper, so as to conduct the magnetic flux as close as possible to the electron beam.
  • the traveling wave tube technique is frequently oriented towards the permanent magnet solution for focusing the beam, because of the conveniences which it brings, in particular from the point of view of the positioning of the focusing pieces and operation of the tube, by removing the continuous source necessary to supply the solenoid.
  • It relates to a traveling wave tube having a structure which makes it possible to avoid, or at least to reduce appreciably, the preceding drawback with regard to the maximum power applicable to the tube.
  • the invention also relates to high frequency amplifier devices using a tube according to the invention.
  • the pole pieces and central wall each carry a collar like the collar 30 of the preceding drawings, a collar made of soft iron or of material with low reluctance.
  • the magnets 22 are provided with lengths in proportion between two pole pieces 3. These flanges are designated in the case of the figure by the same reference 30 for those belonging to a pole piece 3, and by 40 for those located at the end copper walls 16.
