SQUIDによる非破壊検査用クライオスタット

抄録

In recent years, nondestructive evaluation (NDE) by SQUID has been studied by many investigators. SQUID application has great advantages over conventional NDE, such as high sensitivity, high spatial resolution, wide dynamic range, and noninvasion and noncontact character. The SQUID NDE system detects fatigue failure before flaws appear. This paper describes the system and its components. Each cryostat is different for NDE samples and cryostats for NDE systems are explained. Also some NDE examples using SQUID are described.
