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...
A small-scale pseudospark discharge is being investigated as the electron beam source for a klystron operating at a frequency of 94 GHz, and single-gap discharge experiments have been carried out. The klystron has been designed using the particle-in-cell (PiC) code MAGIC-2D and simulated output to date looks promising.

Summary form only given: Demands in plasma diagnostics, radiotherapy, medical research and advanced communications have in recent years resulted in the development of new radiation sources in the terahertz region (0.1 to 10 THz). A klystron is one attractive choice for generation of THz radiation due to its operation mechanism, efficiency and robustness and because its structure is amenable to being...
Experimental studies of the production and propagation of an electron beam from a multi-gap pseudospark discharge chamber are presented. A beam up to 680 A was measured at the anode when a three-gap pseudospark underwent a breakdown at an applied DC voltage of 23 kV. This beam can propagate further downstream as far as 20 cm in length in a gaseous environment (pressure = 60 mtorr) with no guiding...
