Destructive and non-destructive determination of the transport current density radial distribution: application to Bi-2212 textured rods
Destructive and non-destructive determination of the transport current density radial distribution: application to Bi-2212 textured rods
Destructive and non-destructive methods to estimate the radial distribution of the transport critical current, Jc(r), of long cylindrical superconductors are presented. The non-destructive method is based on the measurement of self-field AC losses as a function of the current amplitude, Q(I0) and takes into account the E–J characteristics of the material. Both methods have been used to derive the Jc(r) profiles of long and thin Bi-2212 rods textured by laser-induced zone melting techniques. The obtained results have been correlated with the microstructure of the samples and their critical temperature.

Abstract
Destructive and non-destructive methods to estimate the radial distribution of the transport critical current, Jc(r), of long cylindrical superconductors are presented. The non-destructive method is based on the measurement of self-field AC losses as a function of the current amplitude, Q(I0) and takes into account the E–J characteristics of the material. Both methods have been used to derive the Jc(r) profiles of long and thin Bi-2212 rods textured by laser-induced zone melting techniques. The obtained results have been correlated with the microstructure of the samples and their critical temperature.
