[14p-4A-3] Magnetic coupling between a high-Tc SQUID gradiometer and a flip-chip input coil
Keywords:high-Tc superconductor,SQUID,input coil
We developed non-destructive evaluation systems using high-Tc superconductor, which can be operated under non-shielded environment. The system consists of a detector and SQUID. SQUID gradiometer was utilized, since it works rather stably. A superconducting input coil was prepared on another substrate and was laid above the gradiometer. Magnetic coupling efficiency is determined by design and configuration of the coil and the gradiometer. We investigated the efficiency by using different coils for the identical gradiometer.
