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 work chucking/inserting device for chucking and inserting a work into an insertion hole (cylinder bore) in alignment with the hole, including three or more chuck fingers, the chuck fingers being arranged in circumferentially spaced positions and mounted for advancing and retracting radially. Inner surfaces of the chuck fingers serve as chuck surfaces for chucking the work, and outer surfaces of the chuck fingers are tapered at least at tip end portions radially inward toward the tips for contact with an inlet of the insertion hole. The work chucking/inserting device further includes a tracer mechanism which causes the axis of a conical surface defined by the outer surfaces of the chuck fingers to become aligned with the axis of the insertion hole when the outer surfaces of the chuck fingers contact the inlet of the insertion hole. A pushing mechanism is included for pushing the work toward the insertion hole. The work chucking/inserting device can handle various sizes of workpieces with a simple structure, within a short time and with high working efficiency.

摘要： A particle beam irradiation system capable of ensuring a more uniform dose distribution at an irradiation object even when a certain time is required from output of a beam extraction stop signal to the time when extraction of a charged particle beam from an accelerator is actually stopped. The particle beam irradiation system comprises a synchrotron, an irradiation device including scanning magnets and outputting an ion beam extracted from the synchrotron, and a control unit. The control unit stops the output of the ion beam from the irradiation device in accordance with the beam extraction stop signal, controls the scanning magnets to change an exposure position in a state in which the output of the ion beam is stopped, and after the change of the exposure position, starts the output of the ion beam from the irradiation device again. The control unit further outputs a next beam extraction stop signal when an increment of dose integrated from the time of a preceding beam extraction stop signal as a start point reaches a setting dose stored in advance.
