Abstract

The University of Strathclyde has investigated the applications of electron beams emitted by pseudospark (PS) discharges with an emphasis on their use in the production of radiation in the low terahertz range. To this end, backward wave oscillators (BWO), a form of vacuum tube which utilises the interaction between an axial electron beam and a slow-wave structure, have been designed and modelled using the particle-in-cell code MAGIC before construction of experiments. Successful millimetre radiation generated from BWOs at W-band (75GHz to 110GHz) driven by a 14-gap pseudospark discharge and G-band (140GHz to 220GHz) driven by a 4-gap pseudospark discharge will be presented.
