要約(日本語): The main purpose of this study is to obtain the design, manufacturing techniques and analysis of the compensator for decremented persistent current in the HTS magnet system. In this paper, we have investigated the ramp rate of pumping current into the 6-toroidal load coil of 0.543H for various frequencies during 18 minutes. The simulation results for air gap of the linear type flux pump by using FEM have been compared with the experimental ones. Moreover, we have compared the theoretically calculated of pumping current with experimental results. Through the experimental results we observed that the flux pump can effectively charge the current based on current to load coil for various frequencies. Based on these experimental results, it would be expected that the linear type magnetic flux pump can compensate a little decremented persistent current in the HTS system.
