Demonstration Of An HTS SQUID System For Nondestructive Evaluation

摘要

This report results from a contract tasking University of Strathclyde as follows:This report describes the work done by Dr. Jan Kuznik at the University of Strathclyde from I May 1995 until 31 Jul 1995. In accordance with the proposal, the main objective was to illustrate the feasibility of an eddy current nondestructive evaluation (NDE) measurement system based on high-Tc SQUIDS in an ordinary laboratory environment without any magnetic shielding. A series of aluminum and steel samples with artificial and real cracks were investigated under these conditions.
