Abstract

Eddy currents non-destructive evaluation (NDE) consists in the use of electromagnetic techniques through which the inspection is carried out by detecting magnetic anomalies in the material under examination. The exploitation of the very high sensitivity of SQUID superconducting magnetometers to magnetic flux variations makes it an interesting and promising candidate for magnetic field detection. SQUID (superconducting quantum interference device) magnetometry can allow to overcome the traditional limits due to the lack of sensitivity in conventional electromagnetic NDE techniques. In this paper we present a new project concerning the design of a prototype of a high-temperatui'e SQUID-based NDE instrumentation and its mains applications. © Società Italiana di Fisica.
