Document Type and Number:
Japanese Patent JP6926728
Kind Code:
B2
Abstract:
To provide an operating method of a superconducting magnet capable of ensuring the stability of a magnetic field generated by a superconducting coil in a short time, a superconducting magnet, and an inspection device.SOLUTION: An operating method of a superconducting magnet includes a step (S20) of adjusting the temperature of a superconducting coil formed by winding a superconducting wire rod to a predetermined target temperature, a step (S30) of repeatedly executing excitation and demagnetization of the superconducting coil after the temperature of the superconducting coil reaches the target temperature, and a step (S40) of maintaining the superconducting coil in a superconducting state during execution of excitation and demagnetization of the superconducting coil. The target temperature is set to a temperature at which the superconducting coil is in a thermal equilibrium state during execution of excitation and demagnetization of the superconducting coil cooled to the superconducting state.SELECTED DRAWING: Figure 4
