This item was taken from the IEEE Conference ' Numerical study of pseudospark discharge based electron beam source for terahertz generation ' Terahertz radiation, which ranges from 0.1THz to 10THz, 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 applications1. Klystrons have been designed to generate THz radiation 1,2. This vacuum device requires a very small sized RF circuit and a very thin electron beam with reasonable beam energy. The pseudospark discharge can provide a suitable high current density and small diameter (j1mm) electron beam.
