【Abstract】 In order to improve the dynamic response of CSNS/RCS high frequency system and reduce the influence on RF power source,a direct feedback control subsystem of CSNS/RCS RF system was constructed.In this subsystem,two-stage parallel electronic tetrode was used for feedback closed-loop control,which realizes the functions of large power gain,wide response band and strong shock resistance.The experimental results show that it can effectively improve the stability of CSNS/RCS RF system and suppress the beam loading effect.更多还原
