| Research Abstract |
In this research, we developed a magnetic flux transformers, which was composed of high-temperature superconductor (HTS) wire, to measure weak magnetic signal. It was shown that the noise level of the transformer was about 30 μΦ0/Hz 1/2. We utilized the transformer to construct a ultra-low field (ULF) NMR/MRI system. Based on the system, we measured proton-NMR signal and 1-demensional MRI of water phantom in Earth’ s magnetic field. We also clarified property of magnetic shielding of H TS cylindrical bulks.
