According to one embodiment, there is provided a superconducting magnetic apparatus that conductively cools a superconducting coil contained in a vacuum container with a cryogenic refrigerator. The superconducting magnetic apparatus includes a thermal conductor thermally connecting a cooling stage of the cryogenic refrigerator to the superconducting coil, a radiation blocking layer provided around the superconducting coil, and a coil supporting body supporting the superconducting coil by partial or entire contact with a surface of the superconducting coil.

Superconducting magnetic apparatus

A superconducting coil is provided with a superconducting coil portion having a plurality of concentric coil layer portions. The superconducting coil portion is formed by winding a thin-film superconducting wire and an insulating material with a multilayer structure, wherein the concentric coil layer portions are adjacent to each other at boundary portions having adhesive force that are set to be less than that of other portions. The concentric coil layer portions each has a non-circular shape or circular shape.

Superconducting coil

A superconducting coil quench detection method and device capable of detecting a quench detection voltage even in a superconducting coil where a plurality of element coils are connected with a plurality of current sources and operated with repetitive pulses or AC and a voltage of several kV is applied continuously as an induction voltage. A super conducting power storage unit is also provided.
