Abstract

Abstract

An L-band 10 MW peak power, 150 kW average power multi-beam klystron(MBK) is studied．High quality multiple paracial electron optics system axis are achieved in a uniform, multi-lens magnetic field focusing system. The non-linear calculation of beam-wave interaction is carried for the L-band MBK with six electron beams and six coaxial cavities including a second harmonic cavity. The results show that the multi-beam klystron can produce an output peak power of more than 10 MW, an efficiency of more than 65% and a gain of more than 45 dB with a beam voltage of 115 kV and a beam current of 132 A．
