Abstract
A traveling wave tube has a delay line in the form of a spiral conductor supported within a metallic vacuum shell by a plurality of dielectric support rods. The support rods are covered at least partially with a metalization and soldered together with the delay line and the vacuum shell is shrunk onto the support rods, thus providing a simple structure having good heat dissipating properties.

A method of making a traveling wave tube having a copper vacuum shell, a delay line in the form of a spiral or ring ribbon conductor formed of tungsten or molybdenum arranged between an electron generating system and an electron beam collector, and a plurality of dielectric support rods running parallel to the delay line and interposed between said delay line and the vacuum shell, comprising the steps of;
- providing a metalization on said support rods at locations which contact said delay line, assembling said delay line, said support rods and said vacuum shell, placing the assembly within a thick-walled metal tube and heating said assembly to soldering temperature, whereby said support rods and said delay line are soldered together and said vacuum shell is simultaneously shrunk onto said support rods.
