摘要： PROBLEM TO BE SOLVED: To provide a layer winding type superconducting coil manufacturing method, wherein dimensions of a connection position of an outlet of a superconducting coil can be determined accurately and force is not applied to a superconducting coil after heat treatment. SOLUTION: In the manufacturing method, each single coil is finished accurately separately in processes S1 to S5, and thereafter an aggregate coil is formed in an arrangement process s6 one by one and an inter-laminar gap is charged in an inter-laminar gap charging process S7. Therefore, in a conductor connection process S8, a connection place of an outlet of a single coil is arranged in an almost desired position. Accordingly, an outlet can be connected at a designed normal position, and interface matching with peripheral structures and devices can be performed readily.

摘要： PURPOSE:To stably energize a superconducting coil even if the coil uniformly held at cryogenic temperature is partly exposed by winding a soaking wire blank made of a member having good thermal conductivity on the outer periphery of the coil formed by cylindrically winding a superconducting wire blank. CONSTITUTION:Since a soaking wire blank 3 made of copper having preferable thermal conductivity is wound on the outer periphery of a superconducting coil 2 formed by winding a superconducting wire blank on a cylindrical bobbin 1, the temperature of the wire blank 3 of the part dipped in liquid helium is preferably transferred to the blank 3 of the part exposed from the helium to uniformly hold the temperature of the whole coil 3 disposed at the inner periphery of the blank 3 is uniformly held at the temperature near cryogenic temperature (4.2K) of liquid helium temperature. Thus, no quench occurs as described above even in the state that a superconducting magnet and hence the coil 2 is partly exposed from the helium, but the coil 2 can be stably energized.

摘要： PURPOSE: To contrive to reduce the radiant heat, which infiltrates in a cooling container through a bursting tube, by a method wherein refracted parts are provided with the bursting tube, by which the cooling container and the outside are coupledly connected.
CONSTITUTION: A cooling container 2 has been arranged in the innermost of the cryogenic device, heat shielding tubes 3 have been provided in such a way as to surround this container 2 and these have been all accomodated in a vacuum container 4. Liquid helium 5 has been stored in the interior of the container 2 and a matter 6 to be cooled has been soaked in the liquid 5. Moreover, the container 2 and the shielding tubes 3 have been built in the vacuum container 4, the interior thereof has been held in a vacuum state and vacuum adiabatic layers 8 have been formed therein. Furthermore, a bursting tube 9 having a refracted part at each of two places and having been coupledly connected to the container 2 has been provided at the upper part of the container 2. By providing the refracted parts at two places on the bursting tube 9 like this, the heat radiation from a bursting plate 11 results in being heat-received by the refracted bursting tube 9 itself. As a result, the heat radiation seldom reaches the helium 5, because most of the received heat is absorbed by the shielding tubes 3 joined to the bursting tube 9 and is cooled by liquid nitrogen 7.

摘要： PURPOSE:To reduce the quantity of heat infiltration into a cryogenic refrigerant container by securing a sufficient adiabatic distance contriving the miniaturization of the whole of the container by suspending the cryogenic refrigerant container with a linear support material. CONSTITUTION:Since a cryogenic refrigerant container 4 which is a cryogenic region is suspended at three points by a small heat conductivity insulating wire 9 extended alternately through the outer diameter side and the inner diameter side of mutually different diameter large and small two support rings 10, 11, the adiabatic distance from a vacuum container 8 of a normal temperature region to the cryogenic refrigerant container 4 of a cryogenic region can be made longer and the evaporation of liquid helium 5 can be prevented by reducing the quantity of heat infiltration into the cryogenic refrigerant container 4. The quantity of heat infiltration can also be reduced less by providing a thermal anchor in the middle of the insulating wire 9 since the support rings 10, 11 are so provided as to touch radiation shields 72, 71 respectively.

摘要： PURPOSE:To generate a uniform magnetic field in a highly precise manner as well as to reduce the quantity of helium consumption when a coil quenching process is performed by a method wherein a power source, with which a current is supplied independently to a plurality of superconductive coil sets housed in a fluid helium container, is provided. CONSTITUTION:Two sets of superconductive coils 3 and 4, whereon a superconductive wire of Nb-Ti or Nb3Sn and the like is wound around, are arranged and housed in a liquid-helium-filled container 1 in such a manner that the condition of uniform mag netic field is satisfied. Then, said container 1 is enveloped by a radiant shield 7, and it is placed in a vacuum container 8 through the intermediary of a heat-insulating vacuum layer 6. Subsequently, a current supply part 5 corresponding to the coils 3 and 4 is inserted into the container 8 while the container is being airtightly sealed, they are connected to an exciting power source 10, and the values of current to be applied to the coils 3 and 4 are made independent and allow them to make a change. Through these procedures, a highly precise uniform magnetic field is obtained, and when a quenching is generated by some cause, the current on the coil couple is cut-off, and the quantity of emitted energy is reduced. A permanent current switch may be provided on the coil in this case.

摘要： PROBLEM TO BE SOLVED: To make full use of the capability of a coil by disposing a high-temperature superconducting wire relative to the direction of magnetic field thereof so as to maximize the critical current. SOLUTION: A characteristic of critical current is that a critical current of a magnetic field which is parallel with a tape surface is much larger than that of a magnetic field perpendicular to the tape surface. Therefore, a high-temperature superconducting coil 1 is wound flat around a coil cross section 2, at a position having a maximum magnetic flux density in a direction A of the magnetic lines of force (a). Furthermore, the high-temperature superconducting coil 1 includes the coil section 2 having a small thickness in a diameter direction, and the coil cross section 2 has an extremely small aspect ratio in a direction B of the magnetic lines of force at a position which has maximum magnetic flux density for the coil cross section (b). Moreover, in the high- temperature superconducting coil, magnetic flux density is larger around the surface of the coil 1, as compared with the center of the coil cross section 2. Thus, a superconducting wire around the surface of such a coil is disposed along the direction of the corresponding magnetic lines of force.
