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. Terahertz radiation, which ranges from 0.1 THz to 10 THz, has received substantial interests in recent years. The conventional vacuum electronics technology has the potential to supply high enough powers to underpin many exciting and emerging THz applications. Klystrons have been designed to generate THz radiation. This vacuum device requires a very small sized RF circuit...
