Abstract
A charged particle beam irradiation system comprises a high-speed steerer (beam dump device)disposed in a course of a beam transport linethrough which an ion beam is extracted from a charged-particle beam generator. The beam dump deviceis provided with dose monitoring devicesfor measuring a dose of an ion beam applied to a beam dumpso that the intensity of the ion beam can be measured without transporting the ion beam to irradiation nozzlesA throughD. 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.
