- 摘要：
PROBLEM TO BE SOLVED: To realize a three-dimensional scanning irradiation capable of restraining abstraction of an unintended beam.
SOLUTION: A particle beam irradiation apparatus 1 impresses a charged particle beam, which is accelerated within an accelerator 5 and proceeds through an orbit in the accelerator 5 with an electric field of an RF-KO voltage by an RF-KO electrode 12 opposedly provided in relation to the charged particle beam so as to broaden a width of the charged particle beam, and abstracts a part of the charged particle beam from the accelerator 5 through a deflector electrode 13. The particle beam irradiation apparatus 1 includes a beam selection abstracting control part S1 to control impressing the charged particle beam with a high-frequency electric field that vibrates sympathetically to the frequency of the high charged particle beam, which is likely to be abstracted from the accelerator 5, by the RF-KO electrode 12 when an orbit frequency is so large as to switch the RF-KO voltage OFF.
