【 摘 要 】

The linear arry of 11 HTS SQUIDs discussed in this paper has been developed into a non-destructive evaluation (NDE) tool we refer to as the SQUID array microscope (SAMi). The SAMi is a second-generation device, developed after we built and successfully deployed a single-SQUID NDE instrument. Both the SAMi and its single SQUID predecessor were designed for stockpile stewardship applications at Los Alamos National Laboratory. The stockpile stewardship application is well suited to SQUID NDE techniques. The features of interest are in conductive material, typically small in spatial extent, generally deeply buried (>1cm), and the cost of destructively evaluating a sample is sufficiently high to render the overhead of a SQUID system negligible.
