摘要： A superconductive magnet coolable with a two stage cryocooler is provided. The superconductive magnet includes a cryostat containing a magnet winding, a thermal radiation shield surrounding the magnet winding and spaced away therefrom. The cryostat defines an aperture in which a cryocooler cold head interface receptacle is situated. The interface receptacle has a first and second heat station for connecting in a heat flow relationship with the first and second heat stations of the crycooler, respectively. A precooler has first and second stage heat exchangers connected in a heat flow relationship with the first and second heat stations of said interface, respectively. The interface has an inlet and outlet port for supplying and removing cryogens. Piping means fabricated from heat insulating material connect the first and second heat exchangers in a series flow relationship between the inlet and outlet ports.

摘要： The resistor assembly includes a plurality of resistor sections each in the form of resistive plates in which slots have been cut to provide a continuous resistive element of low inductance. The resistor sections are stacked together with thin insulating sheets separating adjacent resistor sections. The resistor sections are serially interconnected. Taps are provided on selected resistor sections to form a plurality of serially connected resistors in which each resistor is electrically isolated from an adjacent resistor but closely thermally coupled thereto. The resistive plates are bound together by discrete bands of an insulating material such as glass cloth tape. Epoxy impregnation allows the resistor assembly when connected in shunt with series connected superconductive coils to be immersed in the liquid helium of a magnet cryostat without causing excessive pressure rise during a quench event.

摘要： A superconducting magnet includes a coil support structure comprising a body formed of a generally-cylindrical wall. The body includes at least a pair of surfaces facing inwardly of said body, each being of generally-cylindrical shape and each being adapted to abut the radially-outer surface of a respective one of a pair of ring-shaped, superconductive coils. The support structure comprises a material such as aluminum which is adapted to shrink around the coils as the body and coils are cooled to a cryogenic temperature, so as to provide interference fits between the body and the coils. To prevent movement of the coils towards each other due to magnetic attraction forces therebetween, the body includes a pair of shoulders extending inwardly from respective adjacent edges of the pair of inwardly-facing surfaces. The shoulders are adapted to abut confronting surfaces of the pair of coils to prevent the coils from moving towards each other.

摘要： A method and structure for restricting relative sliding motion at the interfaces between a superconducting winding and a supporting structure for the winding. An interface lining material having a low shear modulus of elasticity so as to accommodate large shear displacements with low shear stresses is used as opposed to the use of sliding frictional contact between the contacting surfaces of the electrical winding and the supporting structure. The invention is completed by subjecting the lined interfaced surfaces to large compressional pressure forces so that frictional forces between the interface material and the opposing superconducting winding and supporting structure surfaces, even at low coefficients of friction, are considerably higher than the internal shear forces of the interfacing lining material. The superconducting winding is comprised of a plurality of conductors of superconducting material bunched together in close thermal contact with each other and secured in a solid winding bundle by epoxy resin. The interface lining material preferably is wrapped completely around and surrounds the superconducting winding.

摘要： An apparatus for supporting a stator winding in a superconductive generator. The apparatus includes a plurality of integral stator bars positioned in the air-gap between the yoke and the rotor and a plurality of non-conductive supporting teeth interspaced between the stator bars. The supporting teeth are rigidly attached to the yoke of the generator and are engaged by a plurality of wedge members. The wedge members and the supporting teeth secure the stator bars in a rigid supporting arch.

摘要： Cryogenic liquid coolant for cooling the rotor of a superconducting generator is deposited on the inner surface of a rotating conduit extending within the rotor, forming an annulus of liquid surrounding a vapor core. The liquid coolant from the rotating tube is transferred to two radial tubes in the rotor and, upon emerging therefrom, splashes on the surface of a pool of coolant bathing the rotor windings. Evaporated coolant is returned from the rotor in separate streams from the driven end and the collector end, allowing cooling of the driven and collector ends to be equalized by independently controlling flow of the returning streams.
