The operation can output various carbon-ion beams with different energies in a single synchrotron cycle. The beam control system applying this operation also has been developed to quickly provide the beam energy and intensity required from the irradiation control system. The performance of multiple-energy operation was verified by the experiments at HIMAC. The operation system could output the beams of more than 197 different energies in 63 seconds. The beam intensity could be controlled for their energies without large ripple and overshoot. Experimental irradiation for prostate cancer treatment was also successfully performed, and its result proved that our system can greatly reduce the irradiation time.}, pages = {746--748}, title = {炭素線高速三次元スキャニング照射のための可変エネルギー運転の開発}, year = {2016} }
