High Tc SQUIDs for Unshielded Measuring in Disturbed Environments

Abstract

Directly coupled dc SQUID gradiometers on the basis of YBqCu,O, for unshielded NDE measurements are investigated. The influence of different SQUID layout parameters on the field sensitivity is shown. A sensitivity of 500 ffl(crn.JHz) is achieved with a baseline of 3.6 mrn. A slit in an aluminium plate was detected in an demonstration of NDE in 1 cm depth with eddy current method.
