Abstract

This review paper describes DC-SQUID detectors and SQUID measurement systems used for non-destructive evaluation of materials. Extremely sensitive detectors of magnetic flux, SQUIDs can be used as preamplifiers in setups for measuring many physical quantities. DC-SQUIDs have better energy resolution \(\varepsilon\) and lower noise level Φ r than RF-SQUIDs. Both parameters are discussed in this paper. The best DC-SQUIDs have an energy resolution as good as 0.5h (where h is Planck’s constant). SQUID measurement systems are used not only for material testing and inspection in industry but also in biomagnetic studies (especially in medicine), in geology, military tasks, thermometry and many other fields.
