Multi-beam klystron is a new type of high power microwave amplifier. The S-band multi-beam broadband klystron doveloped in Institute of Electronics, Academia Sinica (IEAS) is described in this paper. The research progresses on the design and calculation of the tube, multi-beam electron gun and focusing system, and broadband output circuit are given. For beam voltage of 19kV and bias voltage of control electrode of -7kV, the measured performances of the tube are as follows: the beam current is 32.25A, beam perveance 12.3μP, DC beam transmission 91.8%, peak power 252kW, average power 3.5kW, the efficiency 41%, the gain 49dB, the band width 9.1% with 1.7dB power variation.
