Abstract :
The Terahertz band of EM spectrum has received considerable research interests recently. A micro-klystron has the potential to meet the requirement of high power and compact terahertz source in many applications. The micro-klystron needs a very thin electron beam with sufficient current density. A pseudospark discharge cathode has the ability to provide high current density with small diameter electron beam (<;1mm).
