摘要： A superconducting magnetic energy storage unit is provided in which the magnet is wound in a toroidal fashion such that the magnetic field produced is contained only within the bore of the magnet, and thus producing a very low external field. The superconducting magnet includes a coolant channel disposed through the wire. The bore of the magnet comprises a storage volume in which cryogenic coolant is stored, and this volume supplies the coolant to be delivered to the coolant channel in the magnet.

摘要： An automated facility for the large-scale production of superconducting magnets for use in a particle accelerator. Components of the automated facility include: a superconducting coil winding machine; a coil form and cure press apparatus; a coil collaring press; collar pack assembly apparatus; yoke half stacking apparatus; a cold mass assembly station; and a final assembly station. The facility can produce, on an economical manufacturing basis, magnets made of superconducting material for use in the ring of the particle accelerator. Each of the components is under the control of a programmable controller for operation having repeatable accuracy. All of the elements which are combined to form the superconducting magnet are thus manufactured with the dimensional precision required to produce a known, uniform magnetic field within the accelerator.

摘要： When a closed circuit is formed by joining superconducting wires with superconducting joints, the current in that circuit adjusts itself as required to maintain whatever total flux linkage the circuit had at the instant superconductivity was achieved. In particular, a closed circuit which first becomes superconducting under conditions of zero net flux linkage maintains zero net flux linkage as long as the circuit remains superconducting. By appropriately configuring a set of short-circuited superconducting coils, a field inside a volume described by the coils is kept substantially more uniform than it would be if the same volume were magnetized by the same source in the absence of the short-circuited coils. This property is used to insure that the volume within the coils exhibits improved magnetic field homogeneity.

摘要： A hydraulically operated, mobile patient transport table useful with a magnetic resonance scanner, which includes a magnet for producing a polarizing magnetic field, employs a hydraulic motor disposed at the base of the magnet and a hydraulic pump disposed at the base of the table. The hydraulic motor and pump are operatively coupled to enable transfer of energy from the motor to the pump without use of hydraulic connections therebetween. In the preferred embodiment, the coupling is implemented with a cone-shaped coupling member attached to the output of the motor and a complementarily-shaped coupling member attached to the input shaft of the pump which frictionally engages the cone-shaped member.

摘要： Even and odd pairs of axisymmetric correction coils are disposed on a cylindrical form at specified longitudinal positions. The coil pairs are intended to provide correction fields for high strength magnets employed in NMR imaging applications. The locations of the coils are chosen so that each coil pair generally contributes to all significant terms in the spherical harmonic expansion representation of the axial magnetic component in the volume within the central region of the cylindrical form except that certain coil pairs are selected and designed so as to fail to produce a particular one of these spherical harmonic component terms.

摘要： A new family of rare earth-rhodium-tin intermetallic compounds, with the representative formula (RE)Rh.sub.x Sn.sub.y, has been synthesized in single crystal form. The compounds containing the heavier rare earths are superconducting and those with the lighter rare earths are generally magnetic. The compound ErRh.sub.1.1 Sn.sub.3.6 exhibits reentrant superconductivity with T.sub.c =0.97 K and T.sub.m =0.57 K as determined from ac magnetic susceptibility measurements. The synthesis and X-ray characterization of the series are described and the results of electrical resistivity, upper critical magnetic field, magnetic susceptibility, specific heat and neutron scattering measurements on the Er compound are given.

摘要： An X-band traveling wave maser of the folded-comb type is provided with two figure-eight coils for gain and bandwidth control. One figure-eight coil covers the full length of the comb structure for bandwidth adjustment of an external magnetic field. The other figure-eight coil covers a central half of the comb structure for independent gain adjustment of the external magnetic field. The half of each figure-eight coil at the turn around end of the comb structure is oriented to aid the external magnetic field, and the half of each figure-eight coil at the input-output end of the comb structure is oriented to buck the external magnetic field. The maser is pumped in the push-push mode with two different frequencies.

摘要： A dipole electromagnet of especial use for bending beams in particle accelerators is wound to have high uniformity of magnetic field across a cross section and to decrease evenly to zero as the ends of the electromagnet are approached by disposing the superconducting filaments of the coil in the crescent-shaped nonoverlapping portions of two intersecting circles. Uniform decrease at the ends is achieved by causing the circles to overlap increasingly in the direction of the ends of the coil until the overlap is complete and the coil is terminated.

摘要： An electrical magnet having at least one turn of electrical conductor which is continuously rippled in small radius arcs around is larger circumference. Each ripple in the conductor is formed to lie in a plane normal to the net magnetic field experienced by that ripple. For the special case of a planar turn of conductor, the ripples lie in substantially the same plane as the conductor turn itself. When current is flowing in the rippled conductor, the conductor will experience a magnetically induced force directed outward normal to the conductor. To oppose this outwardly directed force, the conductor is provided support by means which engage the conductor at the inner portions of the conductor between the ripples therein. The support means may consist of members or columns extending to a solid circular wall as, for example, a wall formed in bedrock. The tensile load in the rippled conductor is much less than in an unsupported large radius circular conductor, and, in addition, the rippled conductor is capable of undergoing expansions and contractions without building up damaging strain levels in the conductor. A superconducting rippled conductor magnet may be thermally insulated from warm support structure by thermal shields and vacuum dewars which are also rippled.
