The purpose of this research is to study, experimentally and theoretically, the injection and focusing of hollow electron beams by electrostatic means. In order to accomplish this type of focusing the electrons must have an angular velocity about the focusing electrode which provides them with a centrifugal force. A program has been started to form the cathode for spiraling beam injection by electroforming. It is planned to use this cathode in an end-fire injection scheme. A computer study of electron trajectories under electrostatic focusing including space charge has been initiated. Author
