    Abstract

    High quality intense electron beams play an important role in high power millimeter-wave and terahertz radiation generation. To this end, the pseudospark-sourced electron beam has been investigated with their applications in different beam-wave interaction structures. Different structures have been designed and modelled using the particle-in-cell codes MAGIC and CST Particle Studio. The experimental demonstration of the PS-sourced electron beams of submillimeter diameter and the coherent millimeter wave radiation generated from PS-sourced electron beams in different beam-wave interaction structures will be presented.
