Abstract

We have developed a High Temperature Superconducting Quantum Interference Device (HTS SQUID)-based eddy current probe that incorporates a Hybrid Double-D (KDD) sheet-inducer coil design for the nondestructive evaluation of conducting materials. Cylindrical high-T _c superconducting shields assist the device´s operation in magnetically noisy environments. Experimental results are presented comparing the flaw response, at various depths, obtained with a conventional sheet inducer with that from the HDD sheet-inducer
