Abstract

A special cylindrical resonator with a coaxial screw and a small apperture above it, is supplied with RF energy. The strong electrical field appearing around the sharp tip on the screw causes pulsating electron emission. By extracting electrons from the emissive region with a system of suitable electrodes, a bunched electron beam can be obtained. This paper presents the design of such a resonator, gives some experimental results and discusses other possibilities regarding its construction.
