摘要
An eddy current nondestructive evaluation system using a low-temperature SQUID magnetic sensor was operated in an unshielded environment. The sensor consists of a niobium de superconducting quantum interference device (SQUID) and a first-order gradiometer pick up coil on the same substrate. We have used the integrated SQUID gradiometer in an unshielded environment to make eddy current nondestructive evaluation measurement on a multi-layer aluminum structure.
