電導体を使用した超電導コイルに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a superconducting coil, and particularly to a superconducting coil using a ceramic superconductor.
従来の超電導コイルはニオブ等の合金の金属線材をコイ
ル状に巻回し、これを液体窒素で、例えば、２３に以下
に冷却して使用されていた。Conventional superconducting coils are used by winding a metal wire made of an alloy such as niobium into a coil, and cooling this with liquid nitrogen to, for example, 23° C. or less.
最近、これに代わって安価で、かつ、取扱い性の良い液
体窒素で冷却できるセラミックス系超電導体の研究が盛

ルを提案した。Therefore, as Japanese Patent Application No. 62-91133 [Superconducting Coil], ceramic superconductors were formed in left-handed and right-handed spirals on or in a ceramic insulating plate. We proposed a superconducting coil in which coiled coils are alternately laminated and ceramic superconductors are connected in series between the laminated layers to form a coil conductor.

のである。The present invention has been made in view of the above, and in order to improve the flexibility of manufacturing conditions by eliminating the need to prepare a ceramic insulating plate having a predetermined shape, a ceramic layer is formed on a metal plate. Right-handed and left-handed spiral ceramic superconductors are formed on the surface of this ceramic layer, and the ceramic superconductors in each layer are electrically connected with the right-handed and left-handed spirals stacked alternately. The present invention provides a superconducting coil which is made into a coil conductor.

In this laminate, the ceramic superconductors of each unit plate are electrically connected to form a coil conductor. To connect ceramic superconductors, for example, in each layer, a penetration part that penetrates the metal plate and the ceramic coating is provided at one end or the other end of the ceramic superconductor, and this penetration part is brought into contact with the ceramic superconductor in the lower layer. This can be achieved by Further, the structure of the laminate may be formed by applying an adhesive between each layer to bond them together, or by applying a mold to the outer periphery to integrate them. When applying adhesive, a spiral pattern must be considered.

ーンにしても良い。Since a ceramic film is formed on a metal plate, a composite plate of metal plate and ceramics can be obtained with extremely high productivity. Since the lattice constant of the ceramic coating of this composite plate can be approximated to that of a perovskite compound, a spiral pattern of a ceramic superconductor can be easily formed by sputtering, IJ, electron beam evaporation, or the like. In this case, it may be formed in a predetermined pattern using a mask, or it may be formed on the entire surface and then etched to remove unnecessary portions to form a predetermined pattern.
