It is difficult by the conventional nondestructive evaluation (NDE) methods to detect recently reported very shallow flaws with less than 50 micron-meter depth on thin copper tubes, or small through holes of less than 0.5 mm in diameter in aluminum flat tubes. Taking advantage of the uncontested high sensitivity of HTS SQUIDs among magnetic sensors, detection of above-mentioned small defects was demonstrated using a newly developed HTS-SQUID NDE system for metallic tubes. So far, a small defect, which volume is about a bit less than 10^7 micron-meter^3, has been successfully detected by the system. With improvement on system noise level, reduction of lift-off distance, and enhancement of excitation field or injected current, it is supposed that the minimum detectable size of a defect could be easily reduced to about 10^6 micron-meter^3. |
