摘要： This invention provides a superconducting magnet apparatus capable of preventing or restraining the heat invading into the apparatus and reducing the refrigeration load of an external refrigerator, at the time of changeover of a switch in transiting to a persistent current mode, and capable of quick changeover operation. In the superconducting magnet apparatus of the present invention (1), in transiting to a persistent current mode, a thermal superconducting switch (41) placed in a low-temperature domain and a mechanical switch (42) placed in a mid-temperature domain are turned on. Since the mechanical switch (42) is placed in the mid-temperature domain, even if a heat load is generated through the drive mechanism (60), it is not necessary to cool the mechanical switch to an extremely low temperature. In short, heat generated at the contact point of the mechanical switch (42) and heat invasion through the drive mechanism (60) are applied not to the low-temperature domain, but to the mid-temperature domain, so that an external refrigerator can easily absorb the heat load and the capacity of the refrigerator can be reduced.

摘要： The invention concerns an NMR (nuclear magnetic resonance) high field magnet coil system comprising superconducting conductor structures for generating a homogeneous magnetic field B0 in a measuring volume (23) with several radially nested solenoidal coil sections (12, 13, 31), which is characterized in that the radially innermost coil section (31) is wound with a band-shaped superconductor with an aspect ratio (width to thickness) >3 on a coil support which axially projects, at least at one axial end, past the winding packet of the radially neighboring coil section (12) and the band-shaped superconductor is guided on this side tangentially towards the outside to a region of reduced magnetic field strength and terminates in at least one electrical connecting point (16). This permits use of a brittle band-shaped superconductor for the innermost coil system (31) which cannot be strongly bent at the upper edge.

摘要： There is provided a power lead for a superconductive magnet capable of controlling the invasion of heat to liquid helium for storing superconductive coils therein and of sufficiently feeding power to the superconductive coils. The power lead for a superconductive magnet of a superconductor magneto unit for supplying a current to the superconductive coils which are cooled at a liquid helium temperature through a radiant heat shielded section which is cooled at a liquid nitrogen temperature, wherein at least a part of sections positioned inside the radiant heat shielded section of a current lead member of the superconductive magnet comprises a high temperature oxide superconductor bulk body having a critical temperature exceeding a liquid nitrogen temperature. In this case, it is preferable to apply a resin impregnation treatment to the bulk body to enforce the high temperature oxide superconductor bulk body section. If at least a part of sections other than the bulk body is formed of a braided wire, a stress caused by the relative displacement between constituents of the unit does not influence upon the bulk body, thereby reducing the risk of breakage of the unit.

摘要： A superconducting very high field magnet coil with several solenoidal multi-layer coil sections which are wound in layers onto a hollow cylindrical support body (3) about a common central axis a, and which are electrically connected in series to carry a current in excess of 100 A is characterized in that the radially innermost coil section (1) comprises superconducting wire (2) which contains oxidic, high temperature superconductor (HTS) material, wherein the layers of the radially innermost coil section (1) are helically wound such that there is a free axial space between the walls, which is then sealed. The corresponding production method comprises the steps of helically winding a layer of superconducting HTS wire together with a filler wire onto the support body; removing the filler wire from the support body; repeating steps (a) and (b) until a desired number of layers of the coil section is obtained; thermally treating the winding packet for reacting the HTS material under a gaseous atmosphere containing O2 with optimized annealing parameters; and sealing the hollow spaces of the coil section. This permits production of an NMR-capable solenoid coil having only a few superconducting joints, of topologically simple construction that can carry a current of a few hundred amperes and which contains HTS material to produce magnetic fields in excess of 21 Tesla.
