PROBLEM TO BE SOLVED: To enable an irradiation in a particle beam cancer treatment to a targeted tumor area while avoiding irradiation to other unaffected organs or important tissue.;SOLUTION: An irradiation particle beam control device 100 of the present invention includes: two first in-plane diffusive electromagnets 111a, 111b provided so as to face across a passage of the irradiation particle beam to generate a magnetic field for diverting the irradiation particle beam from a track axis A to a diffusion direction; two first in-plane convergent electromagnets 112a, 112b provided downstream of the two first in-plane diffusive electromagnets 111a, 111b in a travel direction of the irradiation particle beam so as to face across the passage of the irradiation particle beam to generate a magnetic field for diverting the irradiation particle beam diverted by the two first in-plane diffusive electromagnets 111a, 111b so as to converge to the track axis A; and a support part for supporting the two first in-plane diffusive electromagnets 111a, 111b and the two first in-plane convergent electromagnets 112a, 112b.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
