Achievement of FCC specification in critical current density for Nb3Sn superconductors with artificial pinning centers
X Xu, X Peng, J Rochester +2
In this letter we demonstrate achievement of record non-Cu critical current density (Jc,non-Cu) in ternary, multifilamentary Nb3Sn conductors by the introduction of artificial pinn…
Enhanced higher temperature (20-30 K) transport properties and irreversibility field in nano-Dy2O3 doped advanced internal Mg infiltration processed MgB2 composites
G. Z. Li, M. D. Sumption, M. A. Rindfleisch +3
A series of MgB2 superconducting composite strands co-doped with Dy2O3 and C were prepared via an advanced internal Mg infiltration (AIMI) route.The transport properties and MgB2 l…
Refinement of Nb3Sn grain size by the generation of ZrO2 precipitates in Nb3Sn wires
X. Xu, M. Sumption, X. Peng +1
In this letter we demonstrate that if oxygen can be properly supplied to (Nb-Zr)-Sn wires, ZrO2 precipitates will form during the heat treatment, refining the Nb3Sn grain size mark…
Effects of carbon concentration and filament number on advanced internal-Mg-infiltration-processed MgB2 Strands
G Z Li, M D Sumption, J B Zwayer +5
An advanced internal Mg infiltration method (AIMI) in this paper has been shown to be effective in producing superconducting wires containing dense MgB2 layers with high critical c…
Critical current densities and microstructures in Rod-in-Tube and Tube Type Nb3Sn strands - Present status and prospects for improvement
X Xu, M D Sumption, S Bhartiya +2
In this work, the transport and magnetization properties of distributed-barrier Rod-in-Tube (RIT) strands and Tube Type strands are studied. While Tube Type strands had smaller mag…
The critical current density of advanced internal-Mg-diffusion-processed MgB2 wires
G. Z. Li, M. D. Sumption, M. A. Susner +6
Recent advances in MgB2 conductors are leading to a new level of performance. Based on the use of proper powders, proper chemistry, and an architecture which incorporates internal…
