Definitions

  • a simple construction through the appropriate selection and shaping of the parts of the housing is obtained if the housing has a first tubular housing part made of ceramic in the area of the output screen, the carrier for the output screen at one end and a first electrode by shrinking on at the other end are attached if in the region of the first electrode a second tubular housing part made of ceramic is vacuum-tightly attached to the first housing part, at the other end of which a further electrode is attached. Additional components can be saved if the second housing part is coated on its inner wall with a second electrode. The number of parts can be further reduced if the housing has only one housing part made of an insulating material, on the inner wall of which several electrodes are attached by vapor deposition.
