PURPOSE:To prevent stress from taking place in a superconductive wire of coil, by forming deformed parts in an inner bath containing a conductive coil and thus absorbing an expansion difference between the inner bath and the coil pursuant to elevating up and cooling down of temperature in the case of resin molded superconductive coil. CONSTITUTION:The superconductive coil 1 composed of superconductive wiring molded by resins is contained in a tracklike inner bath 2. This coil 1 is cooled by liquid helium contained in the inner bath. This inner bath is to consist of each inner bath material 2A-2D made of thin plate of stainless steel and expansion joint shells 3A-3D. These joint shells 3A-3D connect the separated parts of the inner bath materials 2A-2D and absorb the expansion difference between the inner bath 2 and the coil 1. Thus, stress is prevented from taking place in the superconductive wiring of coil 1, resulting in a better training effect. |
