Abstract:

A travelling wave tube of the coupled cavity type including a slow wave propagating structure comprised of a linear array of transverse plates axially spaced apart to provide a sequential series of interposed cavities, each of the plates having a cavity coupling aperture radially spaced from an electron beam transmitting aperture and spanned by at least one thermally conductive, dielectric member made of diamond material, which has respective surface areas disposed in thermal contact with opposing side walls of the cavity coupling aperture.
