Abstract: The operation of a repetitively pulsed relativistic klystron amplifier at 100Hz has been reported. The electron beam was reproducibly modulated to >74%. Using a 700kV, 6.5kA, 25ns electron beam and a 500kW Magnetron as inputs, we extracted 1.2GW radiation power in 20ns FWHM pulses at 2.95GHz. The average power is 2.4kW. The efficiency is 24%, and the gain is about 34dB. Limitations attributing directly to the repetitive pulsing at these levels have not been observed.
