Abstract
The inner surface of a barrel for a traveling wave tube is formed with a set of tracks extending parallel to the longitudinal axis of the barrel. The rods supporting the traveling wave tube circuit assembly are supported in the tracks. The tracks are formed by forcing a tool having track-forming elements through the barrel, or a succession of ever-larger tools may be used to first form and then gradually enlarge the tracks.
