Superconducting coils are made of niobium titanium, which exhibits so-called superconductivity, with electrical resistance becoming zero at extremely low temperatures.
It is constructed by winding a superconducting material such as niobium tin, and is used in a superconducting state by immersing it in a cryogenic cooling liquid such as liquid helium and cooling it to a cryogenic temperature below the critical temperature. FIG. 1 shows a general multi-twin-wound superconducting coil, which is constructed by connecting the transition portion conductors 2 at the ends of a unit twin coil 1 to each other. Figure 2 shows a conventional connection state of the transition section, in which a joint section 3 where the transition section conductors 2 from both twin coils 1 are overlapped is joined by soldering or the like, and a thin plate of stainless steel or the like is connected. The reinforcing band 4 is wound to connect the transition parts.

However, superconducting wires made of compound materials are extremely fragile and will deteriorate or break if subjected to small radius bends or shocks.The superconducting wires will be damaged due to strong electromagnetic force at the above-mentioned transition parts even if the joints do not break. In addition, there were drawbacks such as the movement of the transition section due to electromagnetic force and the generation of heat due to friction, which could lead to a transition from a superconducting state to a normal conducting state.
