Abstract

Abstract

The initial experimental results of relativistic klystron amplifier (RKA) driven by linear transformer driver (LTD) pulse power supply are introduced. Hollow electron beam of 600 kV, 6 kA, and 150 ns is generated by foilless graphite cathode. Modulated current of 5 kA, 110 ns is obtained through an input cavity and two idler cavities. The modulated current generates peak microwave power of 820 MW, pulse width of 110 ns, and its efficiency is 28%, its gain is 36 dB. The phase and repetition operation characteristics of RKA are investigated in the experiments. The radiated microwave arrives 800 MW/100 ns, the phase shaking is less than ±20° at 10 Hz.
