1. A particle beam emitting apparatus comprising:

  • an accelerator for extracting a charged particle beam;

    a beam delivery apparatus having a charged particle beam scanning unit and irradiating the charged particle beam extracted from the acceleration;

    an irradiation dose detector that detects the irradiation dose of the charged particle beam applied to an irradiation position in a target; and

    a controller that controls the irradiation of the charged particle beam to the irradiation position so that the irradiation dose applied to the irradiation position becomes a set irradiation dose, in a state where the irradiation dose applied to the irradiation position during the time period from the outputting of a beam extraction stop signal at the time when the irradiation dose detected by the irradiation dose detector reaches the set irradiation dose up to the extraction stop of the charged particle beam from the accelerator, is added.
