Document Type and Number:
Japanese Patent JP7313933
Kind Code:
B2
Abstract:
To improve the stability of the magnetic field by suppressing the magnetic field fluctuation on the order of ppm due to a superconducting coil.SOLUTION: A super conducting magnet 10 includes a superconducting coil 11, a power supply 12 for exciting the superconducting coil, a coil energizing wire 13 that electrically connects the superconducting coil to the power supply, and a protection circuit 15 including a protection resistor 14 connected in parallel with the superconducting coil and in series with the power supply, and is configured to include a temperature variable device 17 that changes the temperature of a part of a variable resistor 18 of the coil energizing wire 13.SELECTED DRAWING: Figure 1
