PURPOSE:To prevent a conductor from heating due to vibration by employing two large and small sector coils made of linear and circular portions to prevent a gap from occurring between winding conductors. CONSTITUTION:The first sector superconductive coil 10 is composed of an outside coil side 10a bent externally in a projecting shape, a linear inside coil side 10b, and connecting coils 10c, 10d. The second sector superconductive coil 11 smaller than the coil 10 is composed similarly to the coil 10 of an outside coil side 11a, linear inside coil 11b and connecting coil sides 11c, 11d. Currents of opposite direction flow to the coils 10, 11 to act a vacuum duct deflecting magnetic field disposed along the sector area. Thus, since the conductors which form the sector superconductive coil can be densely wound therebetween, it can prevent the conductors from heating due to a vibration. |
