Abstract
PURPOSE:To control a bad influence caused by eddy current resulting from outside fluctuating magnetic field with forming uniform magnetic field on the side of a coil axial core of an inner cylinder by locating it on the side of the coil axial core of a cooling medium tank and providing a superconducting substance in a condition that a closed loop is not formed. CONSTITUTION:Superconducting substances 8 which are projected more than then on both end faces in the direction parallel with a coil axial core P of a cooling medium tank 3 is provided on the outer surface at the side of the coil axial core P of the cooling medium tank 3. The superconducting substances 8 are formed of tape-shaped plates 8a composed of niobium and titanium, and both end parts thereof are overlapped only with fixed length S, but, since insulating coats are formed on the tape-shaped plates 8a, they are overlapped and arranged gradually in the direction of the coil axial core P in the condition that a closed loop is not formed and bonded by bonding agent, welding and the like on the outer surface of the cooling medium tank 3. The plates 8a may as well be arranged and bonded in the circumferential direction on the outer surface at the side of the coil axial core P of the cooling medium tank 3.
