  • Abstract
    An electronic axial high-Tc dc SQUID gradiometer cooled by pulse-tube cooler was developed. In order to extend the operating times, a method of temperature control was used to stabilize the operating temperature of the SQUID. We used the SQUID gradiometer cooled by pulse-tube cooler to perform eddy-current nondestructive evaluation and corrosion signal detection in an unshielded environment.
