Abstract
The particle beam irradiation apparatus irradiates a charged particle beam accelerated by a accelerator onto an irradiation subject; the particle beam irradiation apparatus includes a scanning electromagnet that scans the charged particle beam, and a scanning electromagnet moving apparatus that moves the scanning electromagnet in such a way as to change the distance between the scanning electromagnet and the irradiation subject in the beam axis direction of the charged particle beam.
Claims20
A particle beam irradiation apparatus that irradiates a charged particle beam accelerated by an accelerator onto an irradiation subject, the particle beam irradiation apparatus comprising:
- a scanning electromagnet that scans the charged particle beam in an X direction and a Y direction that are perpendicular to a beam axis;
- and
- a scanning electromagnet moving apparatus that moves the scanning electromagnet in such a way as to change the distance between the scanning electromagnet and the irradiation subject in the beam axis direction of the charged particle beam.
