The detection of flaws beside fasteners in aircraft structures is incr
easingly becoming an area where HTS SQUIDs can be successfully applied
. Here, we present noise measurements of MgO bicrystal SQUIDs obtained
in an unshielded environment and with the SQUIDs in motion. We descri
be eddy current NDE experiments using these SQUIDs to detect first and
second layer flaws in simulated aircraft lap-joint structures. (C) 19
