| Outline of Final Research Achievements |
The method to drive high-temperature superconducting magnets efficiently has been studied without using an external power supply and a current lead. The method of using a semiconductor such as a thermoelectric element to the cryogenic side is very compact and can be driven in a simple structure compared to an external power supply. The experiment was performed using a commonly used bismuth tellurium. It was confirmed that it is possible to generate a large and stable current. However, considering the cooling performance of the cryogenic refrigerator used to cool the high-temperature superconducting magnet, it became clear that the device with higher conversion efficiency is needed. A variety of devices were investigated. It was able to find the element which improved the characteristic by low temperature with high conversion efficiency.
