PROBLEM TO BE SOLVED: To suppress an energy cost for operating refrigerators in a refrigerator cooling type superconducting magnet device which are equipped with a plurality of refrigerators. SOLUTION: The superconducting magnet device comprises a superconducting magnet and the plurality of refrigerators for cooling the superconducting magnet. The superconducting magnet device has two modes: an operation mode wherein all of the plurality of refrigerators are operated; and a standby mode wherein some of the plurality of refrigerators are operated while the other refrigerators are stopped.
