Description

Prototype kicker power supplies have been designed for the storage ring beam injection of the Korea 4th generation storage ring (Korea-4GSR). The kicker power supplies drive four bump magnets to maintain field balance and synchronized kick of the beam. The pulsed magnetic field of kickers should be synchronized within a timing jitter of 5 ns and an amplitude difference of ± 0.2%. To fulfill the performance requirements of the kicker power supplies, the pulse-shape matching mechanism among four kickers, and handling two kicker magnets by using one kicker power supply as a parallel driver will be adapted to reduce fluctuation of the kick and the trajectory offset. Specifications of the kicker magnet power supply are the pulse width of 5 us, 200ns flattop width, a half-sinusoidal waveform with the peak current of 7 kA, and 2 Hz repetition rate. In this paper, the circuitry applied to the design of the power supply and circuit simulation will be discussed.
