Abstract
A superconducting magnet device includes a plurality of superconducting coil excitation circuits which each include a superconducting coil and an exciting power supply thereof and are operable independently of each other, a plurality of quenching detectors each of which detects quenching of the superconducting coil of a corresponding superconducting coil excitation circuit, and a controller that, when at least one of the plurality of quenching detectors detects the quenching, controls the exciting power supply of a superconducting coil excitation circuit in which the quenching is not detected among the plurality of superconducting coil excitation circuits to demagnetize the superconducting coil of that superconducting coil excitation circuit.
