20160131726 | MAGNETIC FIELD GENERATION DEVICE - A magnetic field generation apparatus includes a main coil and a variable-current correction coil. The main coil is formed by winding a ReBCO-based superconductive wire rod and generates a magnetic field in a measurement space. The variable-current correction coil is variable in a value of a current, coaxial with the main coil and disposed inside the main coil, and generates a magnetic field which corrects a uniformity of the magnetic field generated by the main coil. | 05-12-2016 |

20140235451 | SUPERCONDUCTING COIL PROTECTION METHOD AND SUPERCONDUCTING MAGNET DEVICE - 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. | 08-21-2014 |
