N2 - Pseudospark (PS) discharge experiments to generate high-brightness electron beams have been carried out at the Strathclyde University, Glasgow, U.K. The PS-sourced electron beam has two phases, an initial 22kV, 50A hollow-cathode phase (HCP) beam of brightness 10^(9-10) A(m*rad)^(-2) followed by a 200V, 200A conductive phase (CP) beam of brightness 10^(11-12) A(m*rad)^-2. The initial HCP beam from an eight-gap PS discharge was applied for the first time in a Cherenkov interaction between the electron beam and the TM01 mode of a 60cm long alumina-lined waveguide. A gain of 29 3 dB was measured and an output power of 2 +/-0.2 kW in the frequency range 25.5–28.6 GHz. Another experiment was focused on the study of the propagation and post-acceleration of the CP beam from a three-gap PS discharge chamber. The beam was successfully accelerated from about 200 V to more than 40 kV.
