The 3.5-cell direct current-superconductive(DC-SRF)photoinjector requires a 1.3GHz 20 kW continuous wave(CW)power amplifier.The R&D of a solid state amplifier(SSA)consisting of 88 unit modules with individual power supplies,which is the first high power(>10kW)CW L-band SSA in China,has been carried out under the cooperation of Peking University and Beijing BBEF Science & Technology Co.Ltd.(BBEF).The RF test results show that the main parameters of this SSA reach the designed values.The efficiency is 34% at ...
