Claim:
1. A device for detecting a quench in a superconducting coil comprising: a first superconducting coil and a second superconducting coil that are connected in series, an intermediate tap that is provided between the first superconducting coil and the second superconducting coil, and a detector configured to measure a first voltage of the first superconducting coil, to measure a second voltage of the second superconducting coil, and to determine the presence or absence of the occurrence of a quench on the basis of a deviation between the first voltage and the second voltage, and on the basis of a stored threshold value, wherein the first superconducting coil and the second superconducting coil have the same shape, wherein a first axis of the first superconducting coil and a second axis of the second superconducting coil are arranged at the same position and in the same direction, and a position of the first superconducting coil and a position of the second superconducting coil in the direction of the first and second axes are the same, and wherein a length of a winding wire of the first superconducting coil and a length of a winding wire of the second superconducting coil are equal to each other.
