Abstract
A control method for a superconducting magnet apparatus comprising steps of: causing a superconducting coil to transition to a superconductive state by causing a cooler to cool the superconducting coil to or below a critical temperature; supplying electric current to the superconducting coil, which has transitioned to the superconductive state, from an excitation power supply; starting a persistent current mode by stopping supply of the electric current; adjusting temperature of the superconducting coil to a specific temperature which is equal to or lower than the critical temperature and higher than a steady operation temperature; and starting a steady operation by cooling the superconducting coil to or below the steady operation temperature, after a specific condition for stabilizing a magnetic field of the superconducting coil is satisfied.
