Outline of Final Research Achievements |
In this research, an experimental and analytical studies were carried out to develop a magnetic field source with small size and high performance of magnetic field (high magnetic field strength, high magnetic field uniformity and high time stability). The proposed magnetic field sources using high temperature superconducting (HTS) wires and bulks were cooled by liquid nitrogen and without any need of power supply after excitation. As a result, we succeeded in designing the HTS magnet which can generate a high performance magnetic field with reducing the amount of use of HTS wire because the cost of HTS wire is still very expensive, and the magnetic field source by stacked HTS bulks was successfully designed and fabricated. We can say that it is possible to obtain the NMR signal using the fabricated magnetic field sources.
