Description
To perform fast beam switching during spot scanning procedure, the kicker system is adopted in HUST-PTF (Huazhong University of Science and Technology Proton Therapy Facility). The rise and fall time is about 100us, and the maximum repetition rate is 250Hz. A high dynamic performance power supply is required to implement the kicker function. Utmost care should be taken to avoid Electro-magnetic disturbances to surrounding equipments caused by high voltage slopes and voltage overshoot. This paper introduces the optimal design and presents the test results of the power supply. A trade-off between voltage slope reduction, overshoots and dynamic performance has been made. The results show that the power supply meets the design specification.
