<P>PROBLEM TO BE SOLVED: To downscale a charged particle beam irradiation apparatus and prevent ingress of radiation from electromagnets from into an irradiation chamber. <P>SOLUTION: The charged particle beam irradiation apparatus 10 includes: a transport line 31 for transporting the charged particle beam; an irradiation section for irradiating the charged particle beam to an irradiation subject; and a rotating gantry 12 for supporting the transport line 31 and the irradiation section and housing a cylinder 13 rotatable around a rotating axis line P; and the slant portion 33 of the transport line 31 passes through the inside of the cylinder 13. Herewith, the amount of overhang of the transport line 31 in the radius direction is reduced, and moreover shielding members 61 and 62 are prepared to shield the radiations from the electromagnets 41, 34 and 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
