摘要： PROBLEM TO BE SOLVED: To lower the generated electromagnetic force of a current collecting coil and restrain the vibration of an outer tank by mounting a current collecting coil at a position where electromagnetic force working on the ground coil side surface of the outer tank in the external direction becomes weak. SOLUTION: Four current collecting coils 311 to 314, 321 to 324, 331 to 334, 341 to 344 are mounted, respectively, at equal intervals for superconducting coils 11 to 14. If the disposing distance of the superconducting coils is L, a pitch (b) for disposing current collecting coils 30 is 1350 mm/4 = 337.5 mm. The pitch (b) becomes smaller than a pitch of 2/3 of the cycle of harmonic generated at the surface of an outer tank. With this constitution, a boundary between the current collecting coil is positioned near a boundary 26 between race track superconducting coils, and the perpendicular conductor of the current collecting coil 30 is not installed on the arc part of the superconducting coil where the outward electromagnetic force of the outer tank is maximum, thus it is possible to lower outward electromagnetic force working on the current collecting coil 30.

摘要： PROBLEM TO BE SOLVED: To prevent degradation of the current collecting capability of a current collecting coil due to a high frequency magnetic field from eddy current generated on the surface of the outer tank of a superconducting magnet. SOLUTION: The beam face on at least the ground coil side of an inner tank beam and the plate face of a radiation shield plate facing the inner tank beam face are regressed to the opposite side of a ground coil, and the outer surface on the ground coil side of an outer tank 2 which is faced to the circular inner side of the inner tank 2 is recessed to the opposite side of the ground coil. As a result of this, an interval between the recessed outer surface of the outer tank 2 and a current collecting coil 5 is widened, and eddy currents generated in the part can be reduced, and the effects of a high frequency magnetic filed due to this can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive, reasonable coil structure that suits the actual service conditions, for use in an electromagnet for an accelerator. SOLUTION: A coil wound on the magnetic pole portion of an iron core is formed of an insulated element wire 8 wound into layers which are bonded together with the adhesive of adhesion layers 41, the adhesion layers 41 having gaps 42 therein which make the adhesion between the element wires discontinuous. An epoxy resin is used as the adhesive of the adhesion layers 41 between the wires 8. Since the coil does not require the element wires to be intimately contacted with one another, it is continuously and gradually graded throughout its periphery to facilitate manufacture, thus varying its cross-sectional form throughout its periphery. The procedure of coil manufacture in conventional use is rationalized, resulting in a large reduction in cost. A method which employs a coil adhesive that sets at room temperature does not require heating equipment and a molding die which were used conventionally in coil molding, and therefore has the effect of omitting a production process such as heating.

摘要： PROBLEM TO BE SOLVED: To provide a superconducting magnet for a distributed induction current collection which has excellent current collecting performance without deteriorating the rigidity of an outer case. SOLUTION: An FRP layer 41 of a current collection coil 6 is engaged with a ground coil side recessed part 12 of an outer case. Since the FRP layer 41 is engaged with the outer case recessed part 12 and they are collectively formed integrally, a board of a ground coil side of an outer case 11 becomes a continuous state, and bending and torsional rigidity of the outer case 11 can be improved. As a result, a superconducting magnet for a distributed induction current collection which is excellent in current collecting performance can be obtained without deteriorating the rigidity of the outer case.

摘要： PROBLEM TO BE SOLVED: To reduce force working to the left and right when a quench occurs on either of the superconducting coils located on the left and right. SOLUTION: A plurality of permanent current switches 31-34 provided on the superconducting coils 21-28 forms a closed circuit. If a quench occurs in one of the superconducting coils, for example coil 21, force working to the right and left will not be generated since the current flowing in the superconducting coils 21, 22 to the left and right is identical. At the same time, the number of permanent current switches is reduced so that the probability of a quench caused by a permanent current switch is lowered.

In this magnet 1, the superconducting coil 7 is arranged at the center of the inner vessel, the width of which is narrowed. The coil 7 is also arranged in proximity to a side surface 2A of the outer vessel at the ground coil side with its center being biased toward the side surface 2A.

摘要： PROBLEM TO BE SOLVED: To stably supply power using electromagnetic induction between a superconducting magnet for magnetic levitation train and a levitation coil and a propulsion coil which are located on the ground and maintain a stable superconducting state for obtaining levitation and propulsion. SOLUTION: On the surface of an outer container 2 of a superconducting magnet 1, located on a vehicle so as to face a levitation coil 14 and a propulsion coil 15 located on the ground, an induction collector coil 11 is so fixed as to face the levitation coil 14. In an inner container 3 holding a superconducing coil 7 in a refrigerant, a superconducting coil 7 is fixed, off-centered to a wall face of the outer container 2 to which the collector coil 11 fixed. For refrigerant through-holes formed in a spacer metal fittings 4 for fixing the superconducting coil 7 in the inner container 3, those formed to the induction collector coil 11 side are made small and those formed to the opposide side, that is, to the truck side are made large. Furthermore, part of a spacer metal fitting 4 near the induction collector coil 11 is formed thicker than the other side of the spacer.
