Abstract
An object of the present invention is to provide a method for protecting a superconducting coil, which method prevents damage to the superconducting coil caused by a quench or the like, in a new way, without using a voltage (a change in voltage) generated in the superconducting coil. Provided is the method for protecting a superconducting coil made by winding tape-like superconducting wire having a superconducting layer. Power from a power supply is shut off based on the magnitude of a screening field, which is a difference between a measured magnetic field B in a direction of a thickness of the superconducting wire at a predetermined position, and a magnetic field Bcal in the direction of the thickness of the superconducting wire calculated disregarding an effect of screening current.
