SUMMARY:High Temperature Superconductors - Professor David A Cardwell\, Pr
 ofessor of Superconducting Engineering\, Department of Engineering\, Unive
 rsity of Cambridge

CONTACT:Dr Nigel Bennee
DESCRIPTION:The discovery of the so-called High Temperature Superconductor
 s in 1987\, which are able to conduct very high electrical currents and he
 nce generate extremely high magnetic fields at liquid nitrogen temperature
 s\, was heralded as the most significant scientific breakthrough since the
  discovery of the transistor.  This talk will describe in a qualitative wa
 y the properties of these remarkable materials\, their manufacture and the
 ir potential for engineering applications\, which include frictionless bea
 rings\, energy storage systems\, MRI and high-field permanent magnets. The
  talk includes a demonstration of magnetic levitation.
