Abstract

An object of the present invention is to estimate, from a cooling performance of a cryocooler in a normal state, whether the cryocooler has cooling performance that enables re-excitation, thereby improving rapidity and reliability of preventing a quench from occurring, and even in a state in which refrigeration performance of the cryocooler is deteriorated in an imaging apparatus such as an MRI apparatus is reduced, to prevent a quench from occurring in advance, and to shorten a time until re-driving and re-imaging. A superconducting coil device includes a superconducting coil housed in a container, at least one cryocooler that is thermally connected to the superconducting coil and cools the superconducting coil, and a processor that inputs temperature information of the superconducting coil detected by a temperature sensor installed in the container and issues a notification to a user. The processor stores a temperature equal to or lower than an excitation-allowable temperature at which excitation of the superconducting coil is allowable as an excitation warning temperature, and issues notification information such as information on cryocooler replacement in a case in which the temperature of the superconducting coil detected by the temperature sensor exceeds the excitation warning temperature for a predetermined time or longer.
