Critical Current Distributions of Recent Bi-2212 Round Wires
Shaon Barua, Daniel S. Davis, Yavuz Oz +4
Bi-2212 is the only high-field, high-temperature superconductor (HTS) capable of reaching a critical current density (16 T, 4.2 K) of 6500 i…
Stable, predictable and training-free operation of superconducting Bi-2212 Rutherford cable racetrack coils at the very high wire current density of more than 1000 A/mm2
Tengming Shen, Ernesto Bosque, Daniel Davis +14
High-temperature superconductors (HTS) could enable high-field magnets much stronger than is possible with Nb-Ti and Nb3Sn, but two key limiting factors have so far been the diffic…
A transformative superconducting magnet technology for fields well above 30 T using isotropic round wire multifilament Bi2Sr2CaCu2O8-x conductor
D. C. Larbalestier, J. Jiang, U. P. Trociewitz +8
We report here that magnetic fields of almost 34 T, far above the upper 24 T limit of Nb3Sn, can be generated using a multifilament round wire conductor made of the high temperatur…
Performance of Titanium-Oxide/Polymer Insulation in Bi-2212/Ag-alloy Round Wire Wound Superconducting Coils
Peng Chen, Ulf P Trociewitz, Matthieu Dalban-Canassy +3
Conductor insulation is one of the key components needed to make Ag-alloy clad Bi2Sr2CaCu2O8+x (Bi-2212/Ag) superconducting round wire (RW) successful for high field magnet applica…
Evidence for length-dependent wire expansion, filament dedensification and consequent degradation of critical current density in Ag-alloy sheathed Bi-2212 wires
A Malagoli, P J Lee, A K Ghosh +6
It is well known that longer Bi-2212 conductors have significantly lower critical current density (Jc) than shorter ones, and recently it has become clear that a major cause of thi…
Reduction of gas bubbles and improved critical current density in Bi-2212 round wire by swaging
Jianyi Jiang, Hanping Miao, Yibing Huang +8
Bi-2212 round wire is made by the powder-in-tube technique. An unavoidable property of powder-in-tube conductors is that there is about 30% void space in the as-drawn wire. We have…
35.4 T field generated using a layer-wound superconducting coil made of (RE)Ba2Cu3O7-x (RE = Rare Earth) coated conductor
Ulf P. Trociewitz, Matthieu Dalban-Canassy, Muriel Hannion +6
To explore the limits of layer wound (RE)Ba2Cu3O7-x (REBCO, RE = Rare Earth) coils in a high magnetic field environment > 30 T, a series of small insert coils have been built and c…
Development of high critical current density in multifilamentary round-wire Bi2Sr2CaCu2O8+x by strong overdoping
T. Shen, J. Jiang, A. Yamamoto +4
Bi2Sr2CaCu2O8+x is the only cuprate superconductor that can be made into a round-wire conductor form with a high enough critical current density Jc for applications. Here we show t…
