【 摘 要 】

Investigation has been undertaken at the University of Strathclyde to simulate, design and construct a klystron amplifier with an operating frequency of 94 GHz. A novel beam source shall be utilized in the form of a pseudospark discharge, a form of low-pressure, high-current plasma discharge which produces an electron beam possessing high brightness as well as self-focusing properties. The seed signal for the klystron will be fed in using a tapered dielectric-lined iris coupling system.
