PURPOSE:To enhance the degree of effective utilization of space, and to increase the necessary feeding quantity of magnetic flux by a method wherein a pancake is brought into an eccentric state, a connecting part for piping and power feeding between coils is arranged in the formed space, and the direction of eccentricity is changed little by little for every coil. CONSTITUTION:Pancake coils 21 (practically a double pancake coil) are arranged on the inside 22 of a toroidal coil group in a 41mm eccentric state. At this time, the connection parts 23 between the pancake coils are arranged by shifting little by little for each pancake coil 21. A power feeding cable 24 and a helium piping 25 are arranged in the space formed by eccentricity, they are spirally positioned along the outer surface of the coil passing in the neighborhood of the connection part 23 between the pancake coils. The feeding quantity of magnetic flux can be increased by the above-mentioned structure of superconducting coil. |
