About

Mike Sumption serves as the associate director of the Center for Superconducting and Magnetic Materials, as well as the Superconducting Technology Center. Dr. Sumption’s background is in materials science and solid state physics. His area of research is materials physics with a concentration in superconductive, electronic, and magnetic materials, with particular interests in:

(i) high performance Nb3Sn, A15 phase formation, and transport properties,
(ii) MgB2 materials, with a focus on formation as well as dopant-induced enhancements of the upper critical fields and the related structural and transport properties,
(iii) Bi:2212 strands and their transport properties
(iv) nanoscale artificial pin structures in multilayer YBCO,
(v) magnetization, AC Losses, flux jumping, and current/field instabilities in superconducting strands,
(vi) flux pinning and connectivity in Nb3Sn and MgB2,
(vi) NbTi, Nb3Sn, Bi:2212, and YBCO-based cables in terms of loss, ICR, and current sharing related to HEP magnet applications.
(vii) oxipnictides, and
(viii) electronic materials and applications.

Efforts in modelling have included stability in Nb3Sn conductors and magnets, anisotropic continuum modeling of bridging and connectivity in superconducting composite structures, field modelling in coils, synergistic pinning in composites, AC loss in various conductors, and fault current limiter design. Materials studies have included rapid quenching and mechanical alloying in Nb3Al, proximity effects in NbTi, and the development of a new class of Nb3Sn strands.

Dr. Sumption’s research has been funded by various organizations, including the US Department of Energy, Division of High Energy Physics, NASA, the Navy, AFOSR, NIH, NRC, the Ohio Department of Development, and private industry. A number of national and international collaborations are ongoing, with universities, national labs, and industry.
