Abstract：
A 40kV/6kA pulsed power supply was designed for the Rapid Cycling Synchrotron (RCS) extraction kicker magnet of the China Spallation Neutron Source. The calculation of the pulsed power supply's parameters, the design of power supply's system, the optimization of pulse forming network (PFN) are introduced in this paper. The magnet current pulse waveform is simulated by PSpice program in the situation of 36.5kV charging voltage. The simulation explains the influence of the PFN section number and the transmission cable
length on the magnet current pulse.
