A new method for improving plasma positional instability was proposed by using high Tc superconductors (HTSCs) and its feasibility was numerically demonstrated. In order to estimate the stabilizing effect of HTSCs with high accuracy, a flux flow and creep (FFC) model should be adopted as the model of shielding current. Here, a flux flow resistivity plays an important role in the evaluation, due to the induction change in HTSCs being large. In this paper, it was verified experimentally that a numerical analysis applying the FFC model is valid, and the flux flow resistivity was evaluated. Furthermore, the dependence of the stabilizing effect on the flux flow resistivity was evaluated by the analysis based on the FFC mode, and a design guideline of high Tc superconducting cable was also indicated.
