Description

There are a number of applications in NDE in which SQUID based instrumentation can potentially provide substantial improvements over room temperature electronics. In addition to direct measurements of the magnetic signatures of cracks and flaws, experiments have shown that SQUIDs may be used as ultrasensitive detectors of AC fields for eddy current detection, detection of magnetic fields due to electrochemical corrosion currents, and detection of NMR signals. Recent results in all these areas will be summarized together with the relative advantage of using SQUID based systems.

Potential new applications of SQUIDs and SQUID arrays in NDE
