Abstract : Efforts continued on the study of stable, well focused, high perveance, large diameter hollow beams. Design objectives for an L-band superpower amplifier klystron, utilizing a high perveance hollow beam, are presented. The tube will be constructed so that rf characteristics of the hollow beam can be examined for beam perveances. The electrical design of a magnetron injection gun is reported. The gun will utilize an inverted geometry (cathode diameter greater than modulating anode) in a tapering magnetic field. The gun will have a convergence in the area of 19. The klystron body is being scaled from an existing L-band tube. The electrical design of the rf structure, including broadbanding techniques to conform to the new design objectives, is presented.
