Abstract

Development of high power relativistic klystron amplifiers (RKAs) at the naval research laboratory is going to be discussed. The present RKA is of a cylindrical geometry and is currently operating in the multi GW range. We are using the present geometry as a test bed for new concepts of high power RKAs. For example, a new geometry of the Relativistic Klystron Amplifier (RKA) was designed. The new RKA will use a thin 45 cm diameter electron beam of 50 GW power. This electron beam will be confined by an external magnetic field between two coaxially grounded metallic tubes. High voltage gaps feeding coaxial cavities will be inserted in the annular drift tube. A 5 MW RF source feeding the cavities will be used to modulate the electron beam. The frequency of modulation can be extended with this geometry to the 10 Ghz region. We predict that 30% - 40% of the power can be extracted as an RF pulse.
