Abstract :
The authors report experimental results on the production of radiation from approximately=20 GHz to approximately=100 GHz in a pseudospark-type device. Pulsed emission of radiation occurs from a low (neutral) pressure ( approximately=100 mtorr Ar) discharge, during the initial transient phase, as the plasma is being formed and a pulsed electron beam is temporarily present. A high-energy electron beam (15 approximately 20 keV) has been observed along with a high-density plasma in this pseudospark-type device. A beam-plasma interaction is proposed as the mechanism for the radiation generation.<>
