Abstract
A slow wave guiding structure such as a helix delay line for electron intction devices of the traveling wave type having diamond heat sink supports for substantial enhancement of power levels of operation is provided. The diamond supported helix structures are maintained in good thermal contact by pressure only in lieu of the diamonds being bonded to metallic members. The invention is applicable to numerous slow wave structures including ladder, ring-bar, meander, as well as interdigital types.
