Abstract

Intrinsic klystrons have been proposed as an RF drive for future high-gradient accelerator structures. Presented are details of experiments in which a 400 keV, 250-500 A electron beam is propagated through X-band TM₀₂₀ cavities to demonstrate high-beam-energy, high-frequency klystron operation. A magnetron supplies microwave power to the initial cavity for amplification. Profiles of the downstream RF magnetic field have indicated that space charge oscillations dominate the klystron beam behavior. Previous small signal experiments are correlated to present high-power results in order to compare gain measurements, beam loading effects, and output RF pulse quality
