Abstract
A particle beam irradiation system having a multi-energy extraction control operation that controls the extraction beam energy in a synchrotron within a short time, such that when the ion beam irradiation is halted, an operating cycle is updated within a short time and a dose rate is improved. To this end, operating control data for each of the devices constituting the synchrotron is constructed by multi-energy extraction control pattern data for controlling extraction of beams of a plurality of energy levels at one operating cycle, and a plurality of sets of deceleration control data that correspond to the extraction control of the beam of the plurality of energy levels. The devices are controlled by using the operating control data.
