摘要： PURPOSE:To reduce an erroneous magnetic filed by a method wherein the direction of an electric current inside a crossover line is changed alternately and a magnetic field formed by an electric current component of a crossover between coils and a crossover between turns is made a higher-order multipole. CONSTITUTION:An electric current of this coil enters from a current entrance 9, flows through a coil 1, a crossover line 6, a coil 3, a crossover line 8, a coil 4, a crossover line 7, a coil 2 and a crossover line 5 one after another and goes out from a current exit 10. Accordingly, the direction of a double-pole magnetic field formed by an electric current 12a of a crossover between turns inside the coils and a crossover line current 13a is opposite to that in an adjacent coil; a multipole magnetic field is formed as a whole. That is to say, the direction of a combination of 12a and 13a is opposite to that of a combination of 12b and 13b; the direction of a combination of 12c and 13c adjacent to it is opposite to that of the combination of 12b and 13b. By this setup, an erroneous magnetic field can be reduced.

摘要： PURPOSE:To restrain a drift generated between superconductuve element wires of multiple core twisted wires, promote a dividing flow, enhance cooling efficiency, and increase a critical current value and a limit current value by providing non-insulating portions not having any insulative film at the surface of the superconductive element wire at intervals larger than a twisting pitch of the superconductive element wire of the multiple core twisted wire. CONSTITUTION:A superconductive filament is disposed in a stabilizing matrix such as copper. Superconductive element wires 1a, 1b, 1c each having an insulating film are twisted in a state of multiple cores and multiple layers on the filament, to be housed inside a conduit 6, thus providing a forced-coling superconductor. Non-insulating portions 7 not having any insulating film are disposed on the superconductive element wires at intervals larger than the twisting pitch lP of the superconductive element wires 1a, 1b, 1c. Formation of unevenness at the surface of the superconductive element wire can increase a cooling area of the superconductive element wire, thus enhancing cooling efficiency as a conductor, i.e., increasing a stable margin so as to improve a limit current value of the superconductor.

摘要： PURPOSE:To lower the composite specific resistance at very low temperatures of a composite material having high purity aluminum as a stabilizer. CONSTITUTION:A composite superconductor 20 is formed by joining a superconducting wire 10 and a composite material 21 together using solder 15, the composite material 21 comprising a tape-shaped copper member 12 joined to the broad surface of high purity aluminum 11 of rectangular cross section. When in use the composite superconductor 20 is disposed with the broad surface of the high purity aluminum 11 being parallel to an external magnetic field H. By disposing the composite superconductor in this way the composite specific resistance of the composite material 21 can be reduced significantly and the specific resistance of the whole conductor can be approximated to that of the high purity aluminum.
