Abstract
There is provided a superconducting magnet device including: a superconducting coil (main coil) in which a superconducting wire material is wound; and a persistent current switch (PCS) electrically connected in parallel with the superconducting coil with respect to an excitation power supply for the superconducting coil, in which the excitation power supply is electrically connected to the superconducting coil and the persistent current switch via a current lead, the persistent current switch is provided with a PCS heater and a PCS heater power supply for transitioning from a super-conduction state to a normal conduction state, and a current supplied to the PCS heater winding from the PCS heater power supply flows to the heater via at least a part of the current lead.
