Abstract

Generally, the high Tc superconductor(HTS) doesn't generate any loss in DC condition, but generate considerable loss in AC condition. Until now AC loss in superconductor has been researched on measuring method of short sample by using electrical method and magnetization method. But it is not easy to estimate AC loss in high class magnet system with results of measuring AC Joss in short sample. In this paper, we carry out research on measuring method by using calorimetric method used in measuring AC loss in high class magnet system. We make the inductive and non-inductive superconducting magnet and measure the generated AC loss, then we compare the measured results with the calculated results using Norris equation. This measuring method of AC loss using calorimetric method can measure not only AC loss in superconducting magnet but losses in conducting, radiant and low temperature. Consequently it is thought that efficient design and fabrication of superconducting magnet system will be possible by means of AC loss measurement method using calorimetric method.
