Pseudospark-sourced micro electron beam for a W-band klystron amplifier

With the aim of producing a high-frequency source of radiation, the University of Strathclyde has been working to design and construct a klystron amplifier with a working frequency of 94 GHz. Following experiments previously carried out at the university on pseudospark discharges, a micro-scale pseudospark discharge is being investigated as the electron beam source for the klystron amplifier. The klystron has been designed using the particle-in-cell (PiC) code MAGIC-2D and simulated output to date looks promising.
