Klystron is a key component of the low hybrid current drive(LHCD)system.It is of great significance to master the power supply and debugging technology of klystrons.The power supply mode of TH2103A klystron is introduced,the debugging method under this mode is summarized,and the relations among the resistance ratio,magnet current,high voltage rise time and anode current are obtained.The anode overcurrent is solved by adjusting the divider resistance,magnet current and high voltage rise time.The debugging process is briefly analyzed.It is concluded that the divider resistance coarsely adjusts anode current,the magnet current finely adjusts anode current,and the high voltage rising time super-finely adjusts anode current.The research provides important experimental basis for the application of TH2103 series klystrons.
