〔産業上の利用分野〕
この発明は、超電導コイルの製造方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a superconducting coil.
従来、超電導コイルは、合金系（Nb―Tiな
ど）の細線を巻いて形成していた。
Conventionally, superconducting coils have been formed by winding thin wires made of alloys (such as Nb-Ti).
最近、飽和磁束密度の高くとれる化合物系超電
導材（たとえばNb3Sn）が、合金系に代つて使わ
れるようになつてた。 Recently, compound-based superconducting materials (such as Nb 3 Sn), which have a high saturation magnetic flux density, have come to be used in place of alloy-based materials.
しかし、化合物系超電導材は機械的にもろいの
で、コイル状に巻くことができないという欠点が
ある。 However, compound-based superconducting materials have the disadvantage that they cannot be wound into coils because they are mechanically fragile.
したがつてコイル状にしてからNb3Sn層を生成
させるという方法をとつており、大型磁石の製作
に難点があつた。 Therefore, the method used was to form the magnet into a coil and then generate the Nb 3 Sn layer, which created difficulties in producing large magnets.
また、超電導コイルは一般に中空コイルの形を
とり、内部に冷媒を流すようにしており、冷媒が
直接超電導線に接触しないため、冷却効率が悪い
という問題もある。 Furthermore, superconducting coils generally take the form of hollow coils in which a refrigerant flows, and the refrigerant does not come into direct contact with the superconducting wires, resulting in a problem of poor cooling efficiency.
この発明は、上記の問題を解消し、効率的な化
合物系超電導体によるコイルの製造を可能にし、
かつ冷却効率のよい超電導コイルの製造を可能と
したものである。 This invention solves the above problems and makes it possible to efficiently manufacture a coil using a compound-based superconductor.
Moreover, it has made it possible to manufacture superconducting coils with good cooling efficiency.
〔問題点を解決するための手段〕（第１〜４図）

ることを特徴とするものである。[Means for solving the problem] (Figures 1 to 4) After forming a layer of superconductor 20 on the entire surface of a pipe-shaped substrate 12 having a layer of normal conductor 16 on the surface, mechanical cutting or etching is performed. This method is characterized in that a spiral superconductor 20 is formed by forming grooves 22 by a method such as the above.
第３図に示すように、パイプ状基板１２は、た
とえばステンレススチール１４のパイプの表面に
銅などの常電導体１６の層をはり合せたものであ
る。
As shown in FIG. 3, the pipe-shaped substrate 12 is made by laminating a layer of a normal conductor 16 such as copper on the surface of a pipe made of stainless steel 14, for example.
基板１２の表面に超電導体２０の層を形成する
には、上記パイプ状の基板１２上の全面に、たと
えばNb3Sn層を形成させたパイプをハンダで貼り
合せたのち、切削などによつてらせん形に連続す
る溝２２を作ることにより（第１図）、Nb3Snの
超電導コイル１０を形成する。 In order to form a layer of superconductor 20 on the surface of substrate 12, a pipe on which, for example, an Nb 3 Sn layer is formed is bonded to the entire surface of the pipe-shaped substrate 12 by soldering, and then by cutting or the like. By creating a continuous spiral groove 22 (FIG. 1), a superconducting coil 10 of Nb 3 Sn is formed.
なお、溝２２の底は、第１図の場合ステンレス
スチール１４の表面にまで達しているが、常電導
体１６の表面または中間までとする場合もある。 Although the bottom of the groove 22 reaches the surface of the stainless steel 14 in the case of FIG. 1, it may reach the surface or the middle of the normal conductor 16 in some cases.
また基板１２は、銅などの常電導体１６だけの
パイプ（ステンレススチール１４の層はない）で
構成することもある。 The substrate 12 may also be comprised of a pipe made of only a normal conductor 16 such as copper (without the layer of stainless steel 14).

記の隙間３０を通つて軸方向にも流れ、超電導体
２０を直接冷却する。 The refrigerant 23 (liquefied hydrogen, etc.) is inserted into the groove 22 of each coil.
The superconductor 20 is directly cooled by flowing inside the superconductor 20 in the circumferential direction (spiral) and at the same time flowing in the axial direction through the gap 30 described above.
なお、超電導体２０を基板１２の外面だけでは
なく、内面に形成する場合、あるいは内外両面に
形成する場合もある。 Note that the superconductor 20 may be formed not only on the outer surface of the substrate 12 but also on the inner surface, or on both the inner and outer surfaces.
また、この発明は化合物系の超電導体の場合だ
けでなく、合金系の超電導体の場合にも適用でき
る。 Furthermore, the present invention is applicable not only to compound-based superconductors but also to alloy-based superconductors.

(1) The superconductor is not formed into a coil system, but the coil is formed from the remaining part after removing unnecessary parts as described above, so no distortion is applied to the coil, and the superconductor is Even if the material is brittle, it can be made without any problems.

ことができる。(3) By applying superconducting coils produced by the method of the present invention by coaxially stacking them,
Since the refrigerant 32 flows spirally within the groove 22 and at the same time flows in the axial direction of the superconducting coil 10 as described above, the flow resistance of the refrigerant 32 becomes much smaller than in the case of a conventional hollow superconductor. A superconducting coil with a large cooling effect can be provided.
