Summary

The authors have integrated Superconducting Quantum Interference Devices (SQUIDs) made from high-temperature superconductors with a portable cryostat and a Joule-Thomson cooler. With these magnetic field sensing systems, flaws in metallic test samples were detected using an adapted eddy-current technique. The paper describes in detail the physical parameters of the two cooling devices, the requirements for the integration of the SQUIDs, and its realization. Furthermore, the authors discuss steps to improve the systems performances.
