    Abstract

    This article presents the investigation of millimeter wave extended interaction oscillation using both pencil and sheet-shaped pseudospark (PS)-sourced electron beams. A W-band (75-110 GHz) pencil beam extended interaction oscillator (EIO) was designed and constructed. In the first experiment the output power of 38 W was achieved from a four-gap PS discharge operating at 30.5 kV. PS-sourced beam generation was further improved by combining a single-gap PS structure with an integrated post-acceleration section in order to enhance the beam quality and increase the output power of the EIO to 200W. The study of a PS-sourced sheet beam EIO structure will also be presented.
