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.

摘要： PURPOSE:To lower the composite specific resistance at very low temperatures of a stabilizer made from high purity aluminum. CONSTITUTION:A composite superconductor 20 is formed by joining a composite material 21 and a superconducting wire 10 together using solder 15, the composite material 21 comprising high purity aluminum 11 of rectangular cross section and a covering material 12 formed on the outside of the high purity aluminum from a material with a Hall coefficient of the same sign as that of the high purity aluminum. When in use the composite superconductor is disposed with the broad surface of the high purity aluminum 11 being parallel to an external magnetic field H. Since the sign of the Hall element of the high purity aluminum is the same as that of the Hall element of the covering material at very low temperatures, the composite specific resistance of the composite material 21 can be reduced significantly by disposing the composite superconductor in this way, and as a result the specific resistance of the whole conductor can be approximated to that of the high purity aluminum.

摘要： PURPOSE:To improve stability when a copper-aluminium compound material is used as a stabilizing material by containing an aluminium material having a copper coating layer in the stabilizing material, and setting a thickness of the copper coating layer equal to or thinner than 35mum. CONSTITUTION:In a superconductor 11, a superconducting wire 3 formed of Nb3S or NbTi and so on of a copper matrix is buried in a copper stabilizing material 2. A groove 4 extending along the wire 3 is arranged on the outer surface of the copper stabilizing material 2, and an aluminium material 13 having a copper coating layer 12, that is, a copper clad-aluminium material 14 is installed in this groove 4 through solder, and a stabilizing material 15 is constituted of the material 2 and the material 14. This layer 12 is formed by means of metal plating and so on, and the thickness is set equal to or thinner than 35mum. Among the layer 12, a part situated in the groove 4 contributes to adhesiveness with the solder, so that stability of the superconductor 11 can be improved significantly. Thereby, the stability can be improved without deteriorating productivity.

Further, the base material 7 is impregnated with thermosetting resin 8 excellent in heat insulation, water resistance, and electrical insulation to produce a semi-cured prepreg sheet 9 which is then inserted between conductors 4. The conductors 4 are then heated while being pressed thus curing the thermosetting resin 8 and integrating the prepreg sheet 9.

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.
