Summary on Grant Application Form |
|
Electromagnetic NDE is seen as one of the best SQUID applications. It has been studied for almost ten years in superconductivity laboratories, but adoption in the field has been slow because of the cost and physical constraints of the sensors and cryogenic equipment. In fact, SQUID performance is indisputably attractive for EM NDE. We wish to study basic developments in sensor and systems design leading to proper exploitation of this performance for the first time. We will design and make integrated sensors comprising low temperature superconductor gradiometric SQUIDs coupled to pick-up coils on the same substrate. (We already make similar sensors for biomagnetism.) Small sensor arrays will be combined with special thin film eddy current excitation coils and a lightweight invertible cryostat to test their operation in a configuration in which the sensor rather than the test specimen moves. The applications we will consider are interlayer and undersurface corrosion and cracking in aircraft and internal cracking in glass-fibre sheathed pressure vessels.
