SUPERCONDUCTING COIL, SUPERCONDUCTING MAGNET EMPLOYING THE SAME COIL, AND MANUFACTURING METHOD OF SUPERCONDUCTING COIL

摘要

PROBLEM TO BE SOLVED: To provide a superconducting coil capable of forming a magnetic field of high spatial uniformity by using a tape-shaped superconducting wire for which a plurality of unit wires are connected, a superconducting magnet employing the coil, and a manufacturing method of the superconducting coil.;SOLUTION: In a superconducting coil 20, a tape-shaped superconducting wire 22 is wound over multiple layers in a solenoid shape while turning the thickness direction thereof towards a spiral radial direction. The superconducting wire 22 is configured by connecting a plurality of unit wires 24 in the length direction thereof, and each of the layers of the coil 20 is configured by winding a single unit wire 24 in a solenoid shape. In a connection part 26 where unit wires 24, 24 are connected with each other in the superconducting wire 22, a terminal portion of the unit wire 24 constituting a radially inside layer and a terminal portion of the unit wire 24 constituting a radially outside layer are overlapped with each other in the thickness direction in a terminal portion of the coil 20.;COPYRIGHT: (C)2014,JPO&INPIT
