摘要:
A method for manufacturing a high-temperature superconducting conductor includes translating an elongated substrate through a reactor. Further, a high temperature superconducting layer is formed on the substrate translating through the reactor by deposition of a reaction product of metalorganic precursor materials onto the substrate. Further, partial pressure of oxygen is monitored to indirectly monitor supply of metalorganic precursors into the reactor.

A superconducting article includes a substrate; first and second buffer layers overlying the substrate, such that the substrate is positioned so as to be interposed between the first and second buffer layers, first and second superconductor layers overlying the first and second buffer layers. Further, the first and second stabilizer layers respectively overlying the first and second superconductor layers, the first and second stabilizer layers adapted to conduct current and prevent burnout of the first and second superconductor layers when the first and second superconductor layers are in a non-superconductive state.

A method for testing a superconducting coated conductor is disclosed. The method includes providing a superconducting coated conductor having an dimension ratio of not less than about 102; and measuring a voltage over a plurality of segments of the superconducting article while applying a constant current Icc.

Disclosed is the structure of a persistent current switch and a control method for the same. In the switch structure, a portion of a superconducting wire to be used as a switch is formed with slits such that the flow of current is controlled by the switch, to facilitate a transition between the superconducting state and the normal state of the superconducting wire. The structure of the persistent current switch includes a first slit longitudinally extending from a first point on one end of a superconducting wire to a second point and from a third point to a fourth point, the second, third, and fourth points being arranged sequentially in a longitudinal line, and second and third slits provided at opposite sides of a region between the second point and the third point where no first slit exists.

Disclosed are a superconductive magnet manufactured by winding a thin superconductive rod wire in a coil without joint for maintaining a persistent current mode, and a method for manufacturing the same. The method includes winding both ends of a superconductive rod wire (10) on a first bobbin (21) and a second bobbin (22) respectively; forming a first unit rod wire (10a) and a second unit rod wire (10b) by slitting the superconductive rod wire (10) in the lengthwise direction; producing a pancake coil by winding the first and second unit rod wires (10a, 10b) on third bobbins (25) in one direction; and arranging the first and second unit rod wires (10a, 10b) such that magnetic fields (B, B′) in the same direction are generated from the pancake coil, by reversing one of the third bobbins (25) on which the first and second unit rod wires (10a, 10b) are wound.
