Millimeter-wave radiation has been successfully generated by a ∼100GHz BWO driven by a high brightness electron beam derived from a 14-gap pseudospark discharge. Pseudospark electron beams have been studied recently with their application to millimeter-wave and terahertz radiation generation. A BWO utilizing the interaction between an axial electron beam and a slow-wave structure was designed and...
High frequency radiation sources in sub-terahertz frequency range (0.1–1 THz) are currently very attractive for both research and technical applications. To generate the high frequency radiation, a pseudospark (PS)-sourced electron beam is ideal because of its scalability accompanied with high intensity and high quality beam generation [1, 2]. The propagation of a PS electron beam is aided by an ion...
A range of pulsed microwave sources, under investigation at the University of Strathclyde, require the generation of multi-kilo-ampere, relativistic, electron beams1,2. These may be mono-energetic or varying in energy throughout the duration of the pulse (dependant on the source in question), however all require a driving supply capable of dealing with potentially rapid changes in the accelerating...
