Presentation Transcript

  1. Superconducting materials for electric power: cable, transformer, FCL Bartek A. Glowacki Reader in Applied Superconductivity IRC in Superconductivity & Department of Materials Science and Metallurgy UNIVERSITY OF CAMBRIDGE Superconductivity and the electricity supply industries 27th November 2003, London

  2. 1. LTS & HTS market prediction • Market and material projections: (a) Price/performance of NbTi, Bi2223 and YBCO conductors versus years; (b) Projections of the LTS and HTS market which is sheared between electronics, power, industrial processing, medical care and transportation. 1995 estimation conducted at International Superconductivity Industry Summit, Yamanashi 1996, numbers corrected according to data in early 2003 (solid lines). Corrected projection conducted at Cambridge University in 2003. • Military use of expensive Coated Conductors is different from civilian market. • Development of YBCO coated conductor is a technology driver, not a Cu or Fe replacement.

  3. Current x length prediction vs time? LTS or HTS or MTS ? Conductor technology TODAY Projections of the LTS and HTS market which is sheared between: electronics, power, industrial processing, medical care and transportation. 1996 estimation conducted at International Superconductivity Industry Summit, Yamanashi 1996, numbers corrected according to data in early 2003 (solid lines).

  4. 1. LTS Jc vs B (a) (b) Transport critical current density vs magnetic field: (a) low temperature superconductors and MgB2 (b) Low temperature superconductors Nb-Al.

  5. NbTi MRI Nb-Ti Cu Nb3Sn Cu NMR

  6. LTS generators and cables

  7. Performance of LTc, MTc and HTc Superconducting conductors Transport critical current density vs magnetic field: (a) low and medium temperature superconductors 1, (b) high temperature superconductors.

  8. Applications

  9. APPLICATIONS Ta 2-10 wt.% ex-situ and in -situ bulks; high-pressure synthesis. @ 20K

  10. Compositional Applicability of YBaCuO conductors and bulk materials Contour lines of Tc, Jc and normalised diamagnetic signal intensity on the fragment of the Y2BaCuO5-BaCu2-CuO phase diagram marked in (a) critical temperature Tc (K); (b) critical current density Jc (Acm-2) at 77K and 0 Tesla; (c) normalised diamagnetic signal intensity.
