    Abstract

    Use of overmoded interaction structures to obtain higher powers from mm-wave vacuum electronic sources is an approach that is being used in the research reported here. To provide mode selectivity a two dimensional corrugated periodic structure is constructed on the inner surface of the conducting cylindrical slow wave interaction region that is excited by an annular electron beam. This two dimensional structure consists of a periodic surface lattice that is designed to facilitate coupling of the wave fields to generate a powerful single frequency output, even though the ratio of the diameter of the structure to the emitted wavelength is ~5. Recent measurements of the output of this mm-wave source are presented.
