Design Study on High Tc Superconducting Plasma Stabilizer

This paper presents design study on application of high Tc superconductors (HTSCs) as a stabilizer for improvement of the plasma vertical instability. For this purpose, an numerical simulation of the overall system including the plasma, the structures and the HTSCs was carried out taking an example of the configuration of the ITER tokamak reactor. Through this simulation, arrangements and parameters of the high Tc superconducting stabilizer are optimized with the consideration of various constraints from the technological viewpoint of the fusion reactor.
