Abstract
A slow-wave electron cyclotron maser consisting of an oversized corrug ated waveguide and an axially injected electron beam has been demonstr ated experimentally. At resonance, the output rf power is strongly enh anced. Maximum output power of 200 kW with an electronic efficiency of 4% at 19.5 GHz is obtained for an electron beam with voltage of 35 kV and current of 150 A. The oscillation is observed to be a periodic TM (01) mode. The enhancement of microwave radiation is estimated to be c aused by the combined resonance of Cherenkov interactions and an anoma lous Doppler shifted electron cyclotron interaction.
