摘要：

To perform fast beam switch during spot scanning and energy modulation procedure, a fast kicker magnet system is adopted in HUST-PTF (Huazhong University of Science and Technology Proton Therapy Facility). The rising/falling time is expected to be less than 100 mu s, and the maximum repetition rate should be up to 500 Hz. To meet the specifications on dynamic response of the power supply, a solution with two separate DC link scheme is present in this paper. Since the Kicker is closed to other sensitive equipment, an output filter is installed to prevent electromagnetic disturbances from propagating along the cables. The optimized design of the output filter and comparison measurement results of the power supply are introduced as well. Here, a trade-off between the voltage oscillation, dynamic performance and engineering implementation has been made.
