Particle beam therapy has become one of the most effective modalities of cancer treatment. High reliability, high throughput and high precision irradiation are strongly demanded for the therapy system. In order to meet the requirements, we have developed several key technologies of synchrotron-based accelerator system, such as multi-harmonic RF acceleration, extracted beam intensity feedback, respiration-synchronized operation and beam tuning for spot scanning irradiation. Almost all these technologies have already been applied to the proton beam therapy system at M. D. Anderson Cancer Center. Beam specifications required for the spot scanning irradiation have successfully been achieved. In this paper, present status of the accelerator development will be described.
