Abstract

The circuit and collector designs for a high-average power S-band multiple-beam klystron are presented. The klystron will be powered by the recently completed 41.6 A, 42 kV, 18-beam electron gun. A compact circuit yielding 680-kW peak power and 13% 1-dB bandwidth has been designed. Design of a high-average power compatible collector for the klystron is also presented. Key issues such as collector power loading and particle reflections due to time-dependent virtual cathode formation set up by the spent (bunched) beam in the collector are addressed.
