INVESTIGATION OF NEW CONCEPTS FOR MICROWAVE POWER GENERATION (LASER STUDIES)

Abstract

An experimental and theoretical investigation of the emission of electrons, ions, and vertical particles from a tungsten cathode which is surface-heated by a laser beam is described. Principal emphasis is given the phenomenon of electron emission because of the interest in its application to the formation of a very dense electron beam. Two different experimental approaches are taken in obtaining electron emission. The first approach is to collect electrons which are ''boiled off'' the surface the laser beam strikes, while the second approach is to use a very thin tungsten ribbon to collect electrons from the surface opposite the one the laser beam strikes. Preliminary theoretical work describing these phenomena is discussed.
