［発明の背朔と目的１
本発明は長手方向で断面寸法の異なる超電導４体及びそ

この超電導４体が接続して用いられていることが多い。Due to demands for economy and miniaturization, superconducting coils are available in two types with different current capacities and dimensions depending on the magnetic field distribution within the coil.
These four superconducting bodies are often connected and used.

ことがあり、超電導特性を劣化させる恐れがある。If the conductor is a monolith type, connection is relatively easy, but if the structure is such that a monolith type or strand type superconducting wire is soldered into a grooved stabilizing material, as in recent large-capacity superconductors, The problem is connecting the grooved stabilizing material. In addition to its role as a stabilizing material, the stabilizing material in the groove often serves as a strength member of the conductor, and is usually made of hard or semi-hard copper material. Therefore, if soft solder is used to connect the grooved stabilizing material, the strength may be insufficient, and when hard soldering or energized heat pressure welding is used, the grooved stabilizing material may become soft and the surface may not be strong enough. Furthermore, when making connections, the superconducting wire embedded in the stabilizing material with claw grooves must be taken out of the groove and re-embedded after connection, which may overheat or damage the superconducting wire. There is a risk of deteriorating superconducting properties.

FIG. 1 shows a monolith type superconducting wire 2 in a groove 4 of a grooved stabilizing material 1 made of, for example, high-purity copper. The figure shows four superconducting bodies having a structure in which the groove 4 is filled with solder and the opening side of the groove 4 is closed with a cover material 3 made of the same material as the stabilizing material '1. However, as shown in FIGS. 4 and 5, the four superconducting members have different thicknesses from the middle in the longitudinal direction. In this case, the grooved stabilizing material 1 consists of a single strip with no connections in the longitudinal direction, and the height of the part defining the groove 4 on the smaller side is higher than the thickness of the superconducting wire 2 compared to the other side. It is lower by the change in . It is desirable that the boundary 5, where the dimensions change, have a slope to avoid sudden changes. Further, the superconducting wires 2 are embedded in a form in which two types of superconducting wires having different sizes (mainly thicknesses) are connected at their sloped ends so that the connecting portion 6 is located near the boundary portion 5.

る（ｈｌ＞ｈ２）長尺の溝付安定化材１が得られる。To prepare the four superconducting bodies configured as described above, first, a grooved stabilizing material 1 of a predetermined length and two types of superconducting wires having different cross-sectional dimensions are prepared. After obtaining the grooved stabilizing material 1 without any connections in the longitudinal direction and having a constant cross-sectional dimension by rolling, dicing, etc.
The opening side of the groove is cut halfway to a predetermined depth and a predetermined length by milling or the like. As a result, as shown in FIG. 2, a long grooved stabilizing material 1 is obtained which is not connected in the longitudinal direction and has different thicknesses from the middle (hl>h2).

よい。The superconducting wires prepared for this stabilizing material 1 are embedded into the wafer 4 through solder in order from the thickest side, for example, and are connected in the vicinity of the boundary 5. The connecting portion 6 may be formed prior to embedding. Thereafter, a lid material 3 is placed on the opening side of the stabilizing material 1.
is attached via solder, and the opening is closed. This lid material 3 may be attached almost simultaneously with the embedding of the superconducting wire 2.

The depth of the groove 4 is selected according to the thickness (j+ and t2) of each superconducting wire 2.
斯くして得られた超電導４体は、コイル製作に提供され

ため、超電導線に損傷を与えることがなく、超電導特性
を劣化させる心配もない。The four superconducting bodies obtained in this way are provided for coil production, but since there is no need to connect the superconducting wire 2 and the stabilizing material 1, the superconducting wire is not damaged and the superconducting properties are not deteriorated. I don't have to worry about letting it happen.
