摘要： A cable includes a plurality of bundles of insulated electrical conductors, each bundle having a first conductor, a second conductor, and a third conductor in a layered configuration. The first conductor of each bundle is connected in parallel to the first conductor of the remaining bundles, the second conductor of each bundle is connected in parallel to the second conductor of the remaining bundles, and the third conductor of each bundle is connected in parallel to the third electrical conductor of the remaining bundles. In addition, within each bundle, the first, second and third electrical conductors are configured so that a magnetic field generated in response to currents flowing within the bundle is zero as seen at a plane oriented transverse to an electrical conduction direction of the cable and located between the ends of the cable.

Rotor windings are supported in the rotor and are formed of a laminated electrical conductor in a single-layer saddle coil configuration. The conductor includes a first support lamina, a second support lamina, an insert including a high temperature superconductor disposed between the first and second support lamina, and a filler material surrounding the insert that bonds the insert to each of the first and second support lamina. At the location between the first support lamina and second support lamina corresponding to the location of the insert, the width dimension of the filler material on each side of the insert is at least 10 percent of a width of the conductor. The conductor is configured to carry at least 600 Amperes per turn and have a C-axis tensile strength of at least 21 MPa.

摘要： The invention provides an apparatus for supplying power to superconducting loads includes a current source, a cryogenic region (e.g., a cryogenic chamber), a first switching device in series between the current source and a superconducting load, and a second switching device in parallel with the superconducting load. The switching devices are arranged so that, when the first is closed and the second is open, recharging current is supplied to the superconducting load. The second switching device serves as a shunt. When it is closed and the first is open, current recirculates through the persistent (or partially persistent) superconducting load. The invention also provides a superconducting magnet incorporating such a power supply.

摘要： A cabled conductor is provided for use in a cryogenically cooled circuit including refrigeration having a predetermined operating temperature and efficiency. The conductor includes multiple conductor strands cabled about the longitudinal axis of the conductor at a preselected cabling period, each strand including a composite of superconducting ceramic in intimate contact with conductive matrix material. Each filament has high performance regions in which the filament material is well-textured with its preferred direction aligned perpendicular to the widest longitudinal cross-section of the conductor alternating with poorly superconducting regions which are at least about half the diameter of a filament in length and in which the superconducting ceramic filament is strained by transposition in excess of its critical strain limit. In the poorly superconducting regions, the conductive matrix material provides an alternate current path. The ratio of the average length of the poorly superconducting regions to the preselected cabling period is less than about (&rgr;300e/&rgr;oe)&egr;E, where &rgr;oe is the resistivity of the composite at the operating temperature; &rgr;300e is the resistivity of the composite at 300 Kelvins; and &egr; is the predetermined efficiency of the refrigeration means at its operating temperature. In the preferred embodiment, this ratio is less than 1:4, and preferably less than 1:20.
