Abstract

This article presents the investigation of a millimetre-wave extended interaction oscillation using both pencil and sheet-shaped pseudospark (PS)-sourced electron beams. Two W-band (75-110 GHz) pencil and sheet beam extended interaction oscillators (EIO) were designed and constructed respectively. The PS-sourced pencil beam EIO structure was firstly driven by a four-gap PS discharge operating at 30.5 kV and the output power of 38 W was achieved. The same EIO structure was then driven by an improved PS-sourced beam produced by combining a single-gap PS structure with an integrated post-acceleration section which generated an output power of 200W. The preliminary PS-sourced sheet beam EIO structure will also be presented.
