This article presents the demonstration of several compact millimetre wave sources driven both by a pencil or sheet electron beam from a pseudospark discharge. The millimetre wave sources include two pencil beam extended interaction oscillators (EIO) in W-band (75-110 GHz), two sheet beam EIOs in W-and G-band, two pencil beam backward wave oscillators (BWO) in W-and G-band, and one pencil beam Cherenkov maser in Ka-band. These devices can generate up to kilowatts of output power, which are very attractive for many important applications.
