Nondestructive Quality Testing of High Temperature Superconducting Bulk Material Used in Electrical Machines and Magnetic Bearings

  • Chapter
Optimization and Inverse Problems in Electromagnetism

Abstract

This paper deals with a non-destructive examination method for high tempera ture superconductors (HTSC’s) based on the scanning of the magnetic field distribution which is trapped by a superconductor. The identification of the positions, dimensions and orientations of sub-domains within the HTSC —which are determining the quality— has been reduced to the determination of the critical current density (JC) distribution within the HTSC using above mentioned measurements. This inverse field problem has been solved by an appropriate numerical algorithm based on extended finite element formulations.
