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.
