CHARGED PARTICLE BEAM IRRADIATION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a charged particle beam irradiation method and apparatus which enable accurate irradiation of an affected part (target) with a charged particle beam even when the direction of the charged particle beam to be irradiated is changed. SOLUTION: Then a rotary irradiator 2 is used to make a charged particle beam emitted from a synchrotron 1 irradiate a target within an irradiation object from a plurality of directions, in the altering of the direction of the irradiation of the charged particle beam to the target made by the rotary irradiator 2, the energy of the charged particle beam in the synchrotron 1 is changed according to the depth position of the target in the irradiation object.
