PROBLEM TO BE SOLVED: To provide a particle beam irradiation system which improves operation efficiency of a synchrotron by reducing energy change control without beam irradiation as further as possible in the case where ion beam irradiation is finished in the middle during a multistage emission control operation of the synchrotron, and an operation method thereof.SOLUTION: Energy ranges Ea-Ej of an ion beam emitted from an ion synchrotron are divided into a plurality of energy ranges, a plurality of operation pattern data items 70 corresponding to the divided energy ranges are prepared, and the plurality of operation pattern data items are combined to form operation control data 7 of equipment forming the synchrotron. At least one of the plurality of operation pattern data items includes initial acceleration control data 701, a plurality of emission control data items 702, reduction control data 706 and energy change control data 705. |
