Numerical Investigation of Pseudospark Discharged Electron Beam and Propagation
In recent years, Terahertz related research have achieved vast interests in different application fields. There are highly demands for compact high power THz radiation sources. One kind of conventional vacuum electron device, klystron, is suitable to be scaled down to generate Terahertz radiation. At high frequency up to THz range, the devices require a very thin electron beam with high current density in order to generate certain output THz power. Pseudospark discharge is one of few possible techniques to provide such a high current beam in tiny size. In this paper, we use numerical simulation techniques to study the detailed hollow cathode pseudospark discharge process and the electron beam propagation along acceleration gap and beam channel with plasma as the background in the absence of a magnetic field.
