PURPOSE:To improve the efficiency of a superconducting magnet coil, by laminating superconducting thin films of ceramic quality or intermetallic compound quality in multiple stages as a spiral structure, and electically connecting the films. CONSTITUTION:Spiral grooves are formed on one surface or both surfaces of a hollow disk shaped substrate 1 made of metal plastics or ceramics. Superconductive material made of ceramic quality or intermetallic compound quality is evaporated in the spiral grooves. A superconductor thin film coil 2 is formed in a spiral shape from an outer terminal point (b) of the disk to an inner terminal point (a). Thus a superconductor board is formed. Said superconductor boards are laminated through insulating films in multiple stages. The spiral coils at all stages are electrically connected in series or in parallel. Thus the superconductive magnet coil having excellent coil efficiency can be formed. |
