Figure 2 shows a typical superconducting coil made by winding. Further, the superconducting coil is cooled by a refrigerant (generally liquid heritum). FIG. 8 shows an enlarged cross section of a part of this superconducting coil. In the figure, the ■ mark indicates the direction of the current, meaning that the current flows from the top to the bottom of the page.

When the tK current flows, the electromagnetic force mentioned above may work and the superconducting wire (2) or the multicore superconducting cable Ill may move. When the superconducting wire (2) or the multicore superconducting cable +11 moves, frictional heat generation occurs there, and the multicore superconducting cable +1
1 may cause superconducting breakdown. The enlightened people made a small superconducting coil by winding a multi-core superconducting cable like the one above and experimented with it. As a result, it was re-recorded that superconducting breakdown occurs at 70% or less of the light leakage current value. Note that it is not preferable to impregnate the entire superconducting coil with epoxy or the like because there will be no gap for the refrigerant to enter between the multicore superconducting cables t11.

ーブルを提供することを目的としている。This invention was made in order to eliminate the above-mentioned drawbacks of the conventional cable, and a semi-hardened varnish is applied between the superconducting wires constituting the multi-core super'K4% cable. The object of the present invention is to provide a multicore superconducting cable that can produce a superconducting coil that is unlikely to cause superconducting breakdown up to a critical current value.

に安定である。FIG. 4 is a sectional view showing a multicore superconducting cable in one embodiment of the present invention. In the figure, +31 is a semi-hardened varnish that is penetrated between the superconducting wires to form a multicore superconducting cable. This semi-hardened alligator (3) is wound as a superconducting coil and then hardened by heat treatment. When a superconducting coil is manufactured using the gold pieces of the superconducting cable (4), the space between the superconducting wire and the superconducting cable (4) is completely fixed due to the presence of the hardened semi-hardened varnish 131. Superconducting wire (21 and superconducting cable (4)
) will no longer move due to electromagnetic force. In addition, since the refrigerant can also enter between the multi-core superconducting cables (4), compared to the case where the entire superconducting coil is impregnated with epoxy etc., the refrigerant is directly bitten by the multi-core superconducting cables (4), which reduces heat. It is stable.

In order to prevent the superconducting cable from moving due to electromagnetic force, the refrigerant can also enter between the multi-core superconducting cables, which reduces the critical current value of the multi-core superconducting cable itself. It is difficult to cause superconducting breakdown until i
This has the effect that a 'a'ms coil can be obtained.
