摘要： A beam extraction process (interruption and restart) is appropriately performed when a failure occurs during irradiation of a spot group. A charged particle irradiation system includes a synchrotron 12 and a scanning irradiation unit 15 that scans an ion beam extracted from the synchrotron over a subject. The extraction of the ion beam from the synchrotron is stopped on the basis of a beam extraction stop command. Scanning magnets 5A and 5B are controlled to change a point (spot) to be irradiated with the ion beam, while the extraction of the ion beam is stopped. The extraction of the ion beam from the synchrotron is restarted after the change of the spot to be irradiated. When a relatively minor failure in which continuous irradiation would be possible occurs during irradiation of a certain spot with the beam, the extraction of the beam is not immediately stopped.

摘要： A charged particle beam irradiation system comprises a high-speed steerer (beam dump device) 100 disposed in a course of a beam transport line 4 through which an ion beam is extracted from a charged-particle beam generator 1. The beam dump device 100 is provided with dose monitoring devices 105, 106 for measuring a dose of an ion beam applied to a beam dump 104 so that the intensity of the ion beam can be measured without transporting the ion beam to irradiation nozzles 15A through 15D. Thus, the system is capable of adjusting the intensity of an ion beam extracted from a synchrotron without operating each component of a beam transport line, and an irradiation nozzle.

摘要： A charged particle beam irradiation system in which the energy, Bragg peak, and irradiation depth of a charged particle beam, with which a patient is to be irradiated, can be checked in real time just before actual irradiation. Just before the actual irradiation, by providing a high-speed steering magnet with 100% current, a checking beam is intentionally hit into a beam damper. By using a dosimeter and a dose measuring device in front thereof, extraction beam intensity is measured. By using a multi-layer beam monitor, a dose distribution thereof is measured. Accordingly, just before the actual irradiation, the energy, Bragg peak, and irradiation depth of the charged particle beam, with which the patient is to be irradiated, can be checked accurately and in real time. When the beam has a desired dose distribution as a result of checking, continuously, extraction control is performed.
