A helix-type delay line borne by a conical surface. The internal surface of a sleeve has grooves into which are inserted dielectric supports of constant height that are affixed to the helix-type delay line, and the depth of the grooves increases with the diameter of the line.

Traveling wave tube comprising a sleeve cut with grooves and its

A delay line for a high frequency tube that is cooled by circulating fluid. The cooling fluid circulates in a duct (FIG. 3, 10), formed in the space between two sleeves (8 and 9). The sleeves are of non-magnetic material, impervious to the cooling fluid, and have an axis parallel to the axis of the delay line. The first sleeve (8), is vacuum tight, brazed or hard soldered to dielectric supports (2) and, in cross section connects two adjacent supports in a straight line. The second sleeve (9), is cylindrical, and contains the first sleeve to which it is brazed at several points. A focusing device made of permanent magnets is mounted on the second sleeve. The invention will find use in high frequency tubes.
