Abstract

Pseudospark (PS) electron beams of outstanding performance have been studied recently with their application to a demanding field of millimeter-wave and terahertz radiation generation. To this end, the PS discharge process itself has been studied and millimeter wave sources which utilize a PS sourced electron beam in different beam-wave interaction structures have been designed and modelled using the particle-in-cell code MAGIC. The experimental demonstration of the PS-sourced electron beams of sub-millimeter diameter and the coherent millimeter wave radiation generated from PS sourced electron beams in different beam-wave interaction structures will be presented.
