て来ている。[Prior art and its problems 1 The superconducting wire of superconducting coils for accelerators contains Nb in copper.
- It is known that a large number of superconducting filaments made of Ti alloy are embedded, but in order to reduce the residual magnetic field of the coil, it is preferable that the filament diameter is small, and in recent years, this type of filament with a diameter of 5 μm or more is also used. It is becoming more and more required.

細化を難しいものにしている。1. With the ultra-fine Nb-Ti filament,
Because the total contact area of the Nb-Ti filament with the stabilized copper increases, during aging treatment, the copper and titanium in the filament react to form a Cu-7i alloy layer at the interface, which causes elongation. This impedes wire workability and makes it difficult to make filaments extremely fine.

An object of the present invention is to provide a superconducting ultra-fine multifilamentary wire that allows ultra-fine i-filaments.

In order to prevent 1 in the Ti filament from passing through and penetrating into the copper portion, it is desirable that the thickness be at least 10 Å or more.
［発明の実施例］

電導線の例を示している。[Embodiments of the Invention] To explain with reference to the drawings, FIG.
An example of a superconducting wire is shown in which a large number of filaments 1 made of an alloy are buried in a dispersed manner in a stabilized copper 2 and the outermost periphery is covered with copper 3.
このような構成の超電導線を作製するためには、先ず第
２図に示すようなシングル線を作り、それを多数本束ね
て伸線加工する。In order to produce a superconducting wire having such a configuration, first a single wire as shown in FIG. 2 is made, and a large number of them are bundled and wire-drawn.

ことができる。The single wire shown in Figure 2 is made by wrapping a Nb-Ti alloy rod in a Nb sheet, storing it in a copper pipe, and then stretching it to form a T with Nb 15 and m116e.
It can be easily obtained by using hNb-Ti alloy II4.

銅層６は安定化銅２となり、第１図に示すような極細多
心線となる。By adding copper wire or not adding copper wire, many of these single wires are housed in a copper tube that becomes copper JI3, and by reducing the area to a predetermined size by extrusion, drawing, etc.
The copper layer 6 becomes stabilized copper 2, and becomes an ultrafine multi-core wire as shown in FIG.
これを更に極細化するためには、その分だけ伸線加工を
行えばよい。In order to make this wire even thinner, it is only necessary to draw the wire accordingly.
また、極細化を多芯化をはかるためには、第１図の多芯
線の作製と同様に、第１図の多芯線の複数本を組合せる
、いわゆる再マルチ組立法を用いて加工を行えばよい。In addition, in order to make ultra-fine multi-core wires, processing is performed using the so-called re-multi-assembly method, which combines multiple multi-core wires in Figure 1, in the same way as the production of multi-core wires in Figure 1. That's fine.

ることができる。As the Nb-Ti filament 1 becomes ultra-fine, the total contact area between the filament 1 and the surrounding material increases;
Between filament 1 and copper 2, there is N, which is not reactive with copper.
Due to the presence of the layer 5 of b, this prevents titanium in the filament 1 from penetrating into the body portion 2 during aging treatment.
It is possible to prevent the formation of Cu-Ti alloy and avoid deterioration in workability.

細の多芯線を得ることができる利点がある。[Effects of the Invention] According to the present invention, a layer of a material that does not react with copper is provided at the interface between the Nb-Ti filament and copper, where a Cu-Ti alloy layer that inhibits workability is likely to be formed. Even if a heat treatment process such as aging treatment is included in the manufacturing process, a cu--r+ alloy layer is generated, which does not impede workability and has the advantage that an ultra-fine multifilamentary wire can be easily obtained.
