Description
Application of a 10 Hz fast-cycling induction synchrotron (IS) to the next generation of heavy ion therapy called Energy Sweep Compact Rapid Cycling Hadron Therapy (ESCORT), where the ion beam with energy sweeping is delivered tracking a tumor target in a deformed and moving organ and monitoring the irradiation dose profile in a real-time during irradiation, is under investigation* ** in the collaboration of KEK and SAMEER. To enable precise targeting, this power supply must allow the deflector magnet to shift the beam irradiation position accurately by varying the peak current value for each pulse with the excitation pattern of the main magnet system. This paper describes the initial experimental results obtained by combining a prototype power supply with a steering magnet.
