Abstract
A rotary irradiation apparatus of an embodiment comprises: a rotating gantry; a superconducting electromagnet being installed in the rotating gantry and forming at least one of a deflecting magnetic field that deflects a trajectory of a charged particle beam and a convergent magnetic field that converges the charged particle beam to guide the charged particle beam to an object to be irradiated; a rotating gantry drive unit that drives/rotates the rotating gantry; and a control device that controls the rotating gantry drive unit to rotate and stop the rotating gantry, while the superconducting electromagnet is being excited and the charged particle beam is not irradiated.

A rotary irradiation method that guides a charged particle beam to an object to be irradiated using a superconducting electromagnet installed in a rotating gantry and forms at least one of a deflecting magnetic field that deflects a trajectory of the charged particle beam and a convergent magnetic field that converges the charged particle beam, the method comprising:
- a step in which a control device controls the superconducting electromagnet to be excited;
- and
- a step in which the control device controls a rotating gantry drive unit to rotate and stop the rotating gantry, while the superconducting electromagnet is being excited and the charged particle beam is not irradiated.
