    摘要: An actuator in which a magnetostrictor is subjected to magnetic fields produced by a superconducting coil, and the magnetostrictor and coil are maintained at temperatures below the magnetic transition temperature of the magnetostrictor and the superconducting temperature of the coil, typically at temperatures in the range of about 4 to about 130 degrees Kelvin. The magnetostrictor is a laminated Terbium Dysprosium (TbDy) alloy structure and the coil includes high temperature superconducting oxide material. The laminations of the TbDy structure are mechanically loaded in compression and each has a thickness substantially equal less than or equal to the depth of field penetration, and a cooler maintains both the TbDy and superconductor at their optimum temperatures.

    摘要: A superconducting magnetic coil formed of anisotropic high temperature superconducting material includes ferromagnetic flanges positioned coaxial to the longitudinal axis of the coil and at the ends of the superconducting coil to capture magnetic flux emanating from the coil so that the maximum perpendicular magnetic field at the end regions is reduced. A reduction in the maximum perpendicular magnetic field increases the critical current at the end regions thereby increasing the critical current at these regions and maintaining an overall higher critical current of the coil.

    摘要: The invention relates to a process for making a superconducting connection between a pair of superconducting ceramic oxide pieces, each of the pieces having been formed by combining the metallic elements of the superconducting oxide in substantially the stoichiometric proportions needed to form the superconducting oxide into a precursor and forming the precursor into a shaped piece. The process comprises the steps of: contacting each of the shaped pieces with the other; connecting each of the shaped pieces to the other by means for forming a metallurgical bond between the shaped pieces; and oxidizing the connected shaped pieces under conditions sufficient to oxidize the metallic elements to the superconducting oxide.In other embodiments of the invention, the process is for forming a superconducting connection between a pair of pieces having a superconducting ceramic oxide/noble metal composition; or for forming a joint between a superconducting ceramic oxide and a normal conductor.

    摘要: The superconducting rotor includes at least one field coil made of a superconductor material having a given superconducting transition temperature. A cryocooler system is mounted for rotation with the rotor. The cryocooler includes a cold head portion mounted in heat transfer relation with the field coil to cool the field coil to a temperature below its transition temperature and includes a piston/regenerator adapted to allow passage of a working fluid at a mass flow rate which is substantially uniform over the cross-section of the piston/regenerator during operation of the system. Heat is conducted away from the field coils by heat pipes or by conduction through high thermally conductive material. Mounting the cryocooler cold head for rotation with the rotor eliminates the use of a cryogenic liquid pool for rotor cooling.
