ABSTRACT:
A plurality of longitudinally disposed dielectric support rods are attached to the outer circumferential surface of a helical slow-wave structure to form a subassembly. The subassembly is mounted in a light press-fit relationship within an enveloping structure comprising a plurality of annular nonmagnetic spacer elements repectively interposed between and abutting a plurality of annular ferromagnetic pole pieces. Plastically deforming force is applied by means of a pair of dies to the outer surface of the spacer elements to crimp the spacer elements onto the support rods and thereby firmly hold the slow-wave structure-rod subassembly within the enveloping structure.
