Definitions

  • the invention relates to an electron tube according to the preamble of claim 1, in particular an electron beam tube such as a traveling wave tube.
  • the electron beam is collected in an electron collector after passing through an interaction area, the energy inherent in the beam electrons being obtained as heat loss in the electron collector, which is also called the collector.
  • the electron collector often consists of a plurality of perforated diaphragm-shaped electrodes of different potentials one behind the other in the beam direction and a bottom part which closes the vacuum space of the tube and which usually heats up considerably.
  • it is known, as already mentioned, to provide several stages or to provide the base part with a spike that spreads the beam.
  • the present invention is based on the object of effectively reducing the thermal load on the component of the electron collector of an electron tube which forms part of the vacuum housing of the tube.
  • FIG. 1 shows a section of a cross section through an electron collector of a traveling wave tube with a cylindrical wall part 1 and a bottom part 2, which is double-walled according to the invention. It consists of the two parts 3 and 4, which form an intermediate space 5.
  • the vacuum envelope is formed by the cylindrical part 1 and the outer wall part 4 of the base part 2, so that there is a vacuum in the intermediate space 5 as well as within the remaining tube 7.
  • the additional wall part 3 of the bottom part 3 has one or more openings 6 for the purpose of pressure exchange, which are arranged in the wall part 3 so that at most a small part of the incoming high-energy electrons 9 can reach the outer wall part 4 through the openings 6 .
  • the advantage achieved thereby is that no strong, selective heating of the outer wall part 4 can occur, so that this component 4 forming the vacuum seal is not subjected to excessive thermal stress.
  • the wall part 3, which is completely in a vacuum can, as it turns out, be subjected to greater thermal loads without damage. It gives off its heat over a large area to the adjacent wall parts of the vacuum housing.
  • FIG. 2 has a plurality of electrode parts 23, 24, 28 fastened in a ceramic tube 21.
  • the bottom part 22 form the two wall parts 23 and 24, of which in turn the outer wall part 24 forms part of the vacuum housing.
  • the inner wall part 23 is provided in the direction of the incoming electrons 9.
  • one or more openings 26 are provided in the wall part 23, which e.g. are so inclined in the wall part 23 that no or only a few high-energy electrons can reach the outer wall part 24 of the double-walled bottom part 22.
  • the outer wall parts 4 and 24 are expediently made thinner than the inner wall parts 3 and 23, the inner wall parts expediently having a wall thickness 2 to 4 times thicker than the outer wall parts 4 and 24.
