Abstract
According to an embodiment, a particle beam acceleration device (12) includes: an incidence section (25) that causes a particle beam (1) to be incident; a guide section (21) that guides the particle beam (1) toward an orbit (3); an acceleration section (24) that accelerates the particle beam (1) that circulates on the orbit (3); an emission section (26) that emits the particle beam (1); a particle beam cutoff section (27) that cuts off the particle beam (1) on the orbit (3); and a control section (30) that controls the incidence section (25), the guide section (21), the acceleration section (24), the emission section (26), and the particle beam cutoff section (27). The guide section (21) includes a superconducting magnet (32) and a superconducting magnet cutoff section (28) that cuts off the superconducting magnet (32). The control section (30) changes an activation sequence of the particle beam cutoff section (27) and the superconducting magnet cutoff section (28) based on at least an operation state of the emission section (26) when an abnormality occurs in the superconducting magnet (32).
