High Field Magnet Programme -- European Strategy Input
B. Auchmann, E. Todesco, A. Ballarino +6
In this submission, we describe research goals, implementation, and timelines of the High Field Magnet Programme, hosted by CERN. The programme pursues accelerator-magnet R&D with…
X-ray studies: Phase transformations and microstructure changes
Christian Scheuerlein, Marco Di Michiel
The goal of this chapter is to illustrate the potential of high energy synchrotron radiation experiments for in situ studies of the processing of superconductors. We present case s…
Nb3Sn wire shape and cross sectional area inhomogeneity in Rutherford cables
U. Kelly, S. Richter, C. Redenbach +7
During Rutherford cable production the wires are plastically deformed and their initially round shape is distorted. Using X-ray absorption tomography we have determined the 3D shap…
Performance Boost in Industrial Multifilamentary Nb3Sn Wires due to Radiation Induced Pinning Centers
T. Baumgartner, M. Eisterer, H. W. Weber +3
We report non-Cu critical current densities of 4.09 * 10^9 A/m^2 at 12 T and 2.27 * 10^9 A/m^2 at 15 T obtained from transport measurements on a Ti-alloyed RRP Nb3Sn wire after irr…
Effects of Neutron Irradiation on Pinning Force Scaling in State-of-the-Art Nb3Sn Wires
T. Baumgartner, M. Eisterer, H. W. Weber +3
We present an extensive irradiation study involving five state-of-the-art Nb3Sn wires which were subjected to sequential neutron irradiation up to a fast neutron fluence of 1.6 * 1…
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…
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…
