摘要： PROBLEM TO BE SOLVED: To reduce technical complicatedness compared with assembled conductor by taking a countermeasure in which drift does not occur even when a plurality of superconducting coils are connected in parallel. SOLUTION: Superconducting coil equipment 10 is constituted in that power supply is performed from a power source 4 prepared outside a low-temperature vessel 1 through a current lead 3, with respect to a plurality of superconducting coil 2 housed inside the low-temperature vessel 1. The power source 4 connects between individual current leads 3 in such a way that, in each superconducting coil 2, its both terminals are separately derived outside the low-temperature vessel 1 through the individual current lead 3.

摘要： PURPOSE:To evaluate the performance via a simple test with a short conductor by forming an LR circuit with two superconducting wires or a superconducting wire bundle, applying pulse voltage or pulse current to it, and measuring the voltage or current. CONSTITUTION:When a conductor to be evaluated uses no insulated strand, two power source connecting superconducting wires 2 extracted from one side of a cable-in-conduit type short superconductor 1 cut with a superconducting twisted wire twisted with a plurality of superconducting wires into a fixed length are connected to a pulse power source 3 via a voltage tap 4 to form an LR circuit. Pulse voltage or pulse current is applied to the short superconductor 1 in the liquid helium where the LR circuit is formed from the pulse power source 3. The voltage generated between the power source connecting superconducting wires 2 or the current flowing in the LR circuit is measured, and the values of the resistance constituent and the inductance constituent of the LR circuit are determined from the delay in phase.

摘要： PURPOSE:To improve the stability and reliability as well as a.c. loss by coating the surface of superconducting wire with amorphos alloy. CONSTITUTION:A superconducting wire to be used at a very low temp. is provided which is coated with amorphos alloy on its surface. Amorphos alloy has the strong joining strength (95kg/mm ) with a base material as well as excellent friction resistance (wear coefficient 0.1 or less), wear resistance and corrosion resistance characteristics, and radiation damage resistance, thereby having a strong resistance to repeated rubbing of the mutual thermally treated conductive wires and a characteristic hard to be peeled off. When applied to a heat treated wire the same effect can be obtained by the use of amorphous alloy of noncrystalline type under the conditions, and in the aspect of assuring a.c. loss characteristic the reliability is improved remarkably. Though the major disturbance and the like on the superconducting wire involved with the safety result from the frictional heat generation caused by movement and the like of superconducting wire, the frictional heat generation can be reduced to the minimum by the use of amorphos alloy with a very small frictional coefficient and the stability is also improved.

摘要： PURPOSE:To provide a superconducting cable with a high stability and less combining loss by arranging a continuous non-insulation part in the longitudinal direction of element wire, on a part of the surface of element wire surface treated on the outer surface thereof. CONSTITUTION:In a superconducting cable in which electrically short-circuited parts are arranged at every sufficiently short distance corresponding to the intergral times of stranding pitches by stranding a plurality of superconucting strands, a non-insulation part 3 continuous in the longitudinal direction of the strand 1 is provided at only one part of the surface of superconducting strand 1 surface treated 2 with thin film organic insulation material, oxide, sulfide or high resistance metal. A stranded unit is formed by the use of such strands 1 and thereby electrical short-circuiting periodical at every stranding pitch can be provided. As a result, even when a fluctuating magnetic field is applied to a cable, the induced voltage in both positive and negative directions in the stranding pitches can be cancelled and even when part of superconducting strand is normal conduction transposed by disturbance, movement of current is made with a small circuit composed of a loop of stranding pitch length, thereby maintaining high stability.

摘要： PURPOSE:To obtain a cryogenic vessel having a long liquid pouring interval by dividing a refrigerant vessel for containing a superconducting coil, etc., into an inner vessel for containing the coil and an outer vessel disposed to surround the inner vessel, and so determining the volumes of the inner and outer vessels as to hole sufficient amounts to stably cool even after the refrigerant is evaporated. CONSTITUTION:The volume ratio of an outer refrigerant vessel 5 to an inner refrigerant vessel 4 is so determined that the refrigerant of the vessel 4 is held in quantity of minimum limit capable of stably cooling a superconducting coil when the refrigerant of the vessel 5 is consumed out. Concretely, when the entire refrigerant amount stored in the vessel is M, the refrigerant amount of the outer vessel is M1, the refrigerant amount of the inner vessel is M2, the total evaporation amount of the refrigerant is m, that of the outer vessel is m1 and that of the inner vessel is m2, an ideal volume ratio and extension of liquid pouring time at that time are obtained by the ratio of m2/m1. The amount m2 of the inner vessel is normally less than that m1 of the outer vessel, and the m2/m1 is 1 or lower.

摘要： PURPOSE:To determine an absolute value of intensity of a magnetic field irrelevant of the direction thereof with the measurement of current flowing through a conductor, by employing a ceramics-based superconductor having no anisotropy for a magnetic field as magnetic field measuring element to apply a DC voltage to the superconductive from a DC power source. CONSTITUTION:A ceramics-based superconductor 1 having no anisotropy as measuring element of a superconductive magnetic flux meter is used and arranged in a liquid nitrogen 9 of a liquid nitrogen reservoir 6 within a vacuum container 4 made of non-magnetic metal or the like. Electrodes 3 are mounted to run current to the superconductor 1 and a DC is supplied to the superconductor 1 kept at the temperature of the liquid nitrogen from a DC power source 11. As the current turns to a critical current corresponding to the intensity of the current magnetic field with a gradual rise in the value thereof, a voltage is generated between the electrodes 3. An absolute value of the intensity of the magnetic field is determined irrelevant of the direction thereof by measuring the value of the critical current.

摘要： PURPOSE:To improve the heat insulating performance of a cryostat by so varying one of porosity and pore diameter that the exhausting performance of a laminated heat insulator nearer to an inside vessel becomes easier to reduce transmitting heat due to remaining gas between the layers of the insulators, thereby decreasing an increase in radiation heat. CONSTITUTION:Laminated heat insulators 2-4 are formed by depositing metal such as aluminum on one or both side surfaces of a Myler sheet and perforating pores 9. The pores 9 are smaller at the inner positions, the number of the pores is increased, the porosity of the pores is stepwisely varied in the layers of the insulators, and increased more at the inner side of the vessel. The porosity is approx. 0.5-1.0% at the outer layer of the insulator and 2-4% at the inner layer side, and stepwisely varied in the range of this porosity in the layers therebetween. Since the porosity is increased larger and the diameters of the pores are reduced toward the inner layer insulators 4 of low temperature side, vacuum at the inner layer is improved to reduce transmitting heat due to gas between the layers.
