Particle beam accelerator, particle beam blocking method for particle beam accelerator, and particle beam therapy apparatus

Abstract

According to one embodiment, a particle beam accelerator comprising: a guiding unit configured to guide a particle beam to a trajectory; an acceleration unit configured to accelerate the particle beam circulating on the trajectory; a particle beam blocking unit configured to block the particle beam on the trajectory; and a control unit configured to control the guiding unit, the acceleration unit, and the particle beam blocking unit, wherein: the guiding unit includes a superconducting electromagnet and a superconducting electromagnet interrupter configured to interrupt the superconducting electromagnet, and the control unit is configured to interrupt the superconducting electromagnet by activating the superconducting electromagnet interrupter after completion of blocking the particle beam by activating the particle beam blocking unit, when an abnormality occurs in the superconducting electromagnet.
