  • Total AC Loss in Twisted Multifilamentary Coated Conductors Carrying AC Transport Current in AC Transverse Magnetic Field

    Numerical electromagnetic field analysis was made to study the total AC loss characteristics of twisted multifilamentary coated conductors carrying AC transport current in an AC transverse magnetic field. The superconducting property was represented with the power law E – J(electric field—current density) characteristic, and the magnetic field component tangential to the wide face of a conductor was neglected to use a thin strip approximation with which current and magnetic flux distributions on a wide face of a coated conductor can be calculated. The transverse resistance between filaments, the amplitude of the transport current, and that of the transverse magnetic field were varied to study magnetic flux penetration processes and total AC loss characteristics.

  • Joint resistance measurement using current-comparator for superconducting wires in high magnetic field

    To assess the joint resistance between superconducting multifilamentary wires in a magnetic field, a measurement system using a current comparator has been developed for measuring the current decay induced in a superconducting loop containing a joint. It can measure both joint resistance and joint current carrying capacity up to 3000 A in a maximum magnetic field of 6.6 T. The joint resistances between superconducting wires soldered by diffusion welding and cold-pressing welding methods have been measured. The joint performance in magnetic fields of up to 6 T has been recorded.<<ETX>>

  • 50 tesla superconducting solenoid for fast muon cooling ring

    A conceptual design is presented for the 50 Tesla superconducting solenoids that are required for an optimized fast cooling ring in current designs for multi-TeV muon colliders. The solenoid utilizes high-performance multifilament Bi-2212/Ag round strand. The conductor is a cable-in-conduit consisting of six such strands cabled around a thin-wall spring tube then drawn within an outer sheath. The spring tube and the sheath are made from high-strength superalloy Inconel. The solenoid coil comprises 5 concentric shells supported independently in the conventional manner. Each shell consists of a winding of the structured cable, impregnated in the voids between cables but empty inside so that the spring tubes decouple stress so that it cannot strain- degrade the fragile strands, and a high-E stress shell. An expansion bladder is located between the winding and the stress shell. It is pressurized and then frozen to provide hydraulic compressive preload to each shell. These provisions makes it possible to accommodate ~10 T field contribution from each shell without degradation, and to distribute refrigeration so that heat is removed throughout the volume of the windings.

  • Some aspects of cable design for fast cycling superconducting synchrotron magnets

    The world's experience in application and manufacturing of superconducting cables for fast cycling synchrotrons (operating frequency f = 1 Hz) is limited up to now to a hollow multifilament NbTi cable cooled with two-phase helium flow. The cable of 7 mm in diameter has critical current of 8400 A at B = 2.5 T and dB/dt = 4 T/s. The degradation of critical current does not exceed 10% up to dB/dt = 8 T/s. The cable was designed and has been used for the magnets of the Nuclotron superconducting synchrotron at JINR in Dubna. The recent R&D was motivated by the new project of a superconducting synchrotron SIS100 at GSI in Darmstadt. Besides the basic option, i.e., the present Nuclotron-type cable, other design options are proposed. Their suitability for application in the conditions specified for the SIS 100 are considered. The improved characteristics of the Nuclotron-type cable and the magnet coil parameters are also presented.

  • Titanium Doped<formula formulatype="inline"><tex Notation="TeX">${\hbox {Nb}}_{3}{\hbox {Sn}}$</tex></formula>Superconductor Fabricated by the Internal Tin Tube (ITT) Approach

    Multifilament Nb3Sn superconductor has been produced by the internal tin tube (ITT) approach. The process employs tubular niobium filaments with cores consisting of tin or high tin alloy inside a copper sheath. The niobium annulus of each filament contained eight Nb-47Ti ldquoislands.rdquo During the subsequent reaction heat treatments the titanium was diffused out of these islands and throughout the niobium annulus resulting in a calculated titanium concentration of 1.5 wt%. The process holds the promise to minimize the amount of non-superconducting area in the conductor cross section and thereby maximize non-copper critical current density. Niobium tube fabrication, wire processing, filament quality, and microstructure are discussed, and superconducting properties are presented.

  • Development of Nb/sub 3/Al multifilamentary superconductors

    Nb/sub 3/Al/Cu multifilamentary strands fabricated by the Jelly-roll process, and cable-in-conduit conductors have been developed for fusion magnets. The recent strand has achieved a high critical density of 800 A/mm/sup 2/ (12 T, 4.2 K) with a feasible heat treatment condition for large coils or conductors. The improved strands have were also confirmed to good bending and tensile strain tolerance. A cable-in-conduit Nb/sub 3/Al superconductor with 1152 strands was also developed. It has a titanium conduit and center tube, conforming to the current design for ITER magnets.<<ETX>>

  • Design considerations of superconducting magnets as a Maglev pad

    Design considerations are made on the superconducting magnet as a Maglev pad. The superconducting magnet, called L-type because of its geometry, has two superconducting coils. One is vertically oriented for thrust and guidance, while the other is horizontally oriented for suspension, in one cryostat. The two superconducting coils are both 4 m in length, extremely long in comparison with those that have been constructed so far. Winding techniques of such long coils and structure of a cryostat meeting the contradictory requirements of light weight and solidity are discussed. One of the guiding philosophies of this project was to construct a superconducting magnet with easy operation and simple maintenance, keeping a practical train in mind. In order to meet these requirements, all operating controls, liquid helium inlet valves and current leads were located on the front panel of the cryostat.

  • On the Feasibility of a Tripler Upgrade for LHC

    The design of high-field dipoles has been optimized using a block coil geometry. The optimization includes stress management and flux plate suppression of multi-poles from snap-back. The design has been extended to higher field by devising a hybrid coil geometry containing inner windings of Bi-2212 and outer windings of Nb<inf>3</inf>Sn. A 24 Tesla dual dipole using this design offers the possibility of an LHC tripler. Issues of fabrication technology and synchrotron radiation control are discussed. There is no obvious upper limit to the field that could be attained for the dipoles of future hadron colliders.

  • Mechanical Analysis of the Superconducting Outsert for the Series Connected Hybrid Magnets

    The NHMFL presently has three series-connected-hybrid (SCH) projects, two of which are entering a construction phase. The design of the SCH outsert magnets is based on a CICC configuration using cable of multi-filamentary Nb<sub>3</sub>Sn and Cu strands inside a stainless steel jacket cooled by forced flow supercritical helium at 4.5 K. The outsert coil design is presented along with the design criteria for the evaluation of conduit and conductor insulation components. The results of detailed finite element analysis performed for normal, quench and fault load conditions are discussed to ensure the levels of stress and strain in conduit and insulations satisfy the design criteria. The conduit evaluation of fatigue life and fatigue crack growth rate (FCGR) is performed and the results are discussed for a possible cyclic lifetime and a minimum detectable flaw size for the SCH outsert.

  • Development of ductile, high current density multifilament niobium-titanium superconducting wire for SSC corrector magnets

    A superconducting corrector magnet wire was developed for the Superconducting Super Collider (SSC) which surpassed all performance specifications. Critical current requirements were met while maintaining the high degree of ductility necessary for manufacturing the intricate magnet coils. Data suggest that ductility specifications can be met with current densities exceeding 3000 A/mm/sup 2/ at 5 T. Indications are that electrical performance can be further increased without compromising piece length, ductility, or manufacturability.<<ETX>>
