Abstract :
A micro-klystron is one kind of compact device which can generate high power Terahertz radiation to meet the requirements of fast growing applications in Terahertz technology. The device needs a very thin electron beam with high energy to drive the beam-wave interaction. Pseudospark discharged electron beam has demonstrated its ability to provide a high current density in a small diameter (<; 0.2mm) for a W-Band micro-klystron.
