摘要： PROBLEM TO BE SOLVED: To safely and efficiently perform irradiation with improved irradiation accuracy by appropriately performing a beam emission processing (interruption and restart) when an abnormality occurs during the irradiation of spot aggregation.SOLUTION: A particle beam irradiation system includes: a synchrotron 12; and a scanning irradiation device 15 having scanning electromagnets 5A, 5B and scanning an ion beam emitted from the synchrotron 12. The emission of the ion beam from the synchrotron 12 is stopped on the basis of a beam emission stop command. In this state, the scanning electromagnets 5A, 5B are controlled to change ion beam irradiation positions (spots). After the change, the emission of the ion beam from the synchrotron 12 is started. When a comparatively slight abnormality capable of continuing the irradiation occurs during the irradiation of the beam to a certain irradiation spot, the beam emission is not immediately stopped but is stopped when the irradiation is completed concerning the whole spots belonging to the predefined spot aggregation including the irradiation spot.
