Study of Plasma Equilibrium Control for JT-60SA using MECS

Abstract

A magnetohydrodynamic equilibrium control simulator (MECS) has been developed to study the techniques of plasma equilibrium control in JT-60SA. The new modules of the plasma shape reconstruction, power supply, and simulated poloidal field coils are incorporated into MECS to simulate plasma equilibrium control considering the power supply capability and the influence of the identification error between the actual and reconstructed plasma boundary, just as in a real plasma experiment. The MECS uses the Cauchy condition surface (CCS) method for plasma shape reconstruction. Plasma equilibrium control is demonstrated during the heating phase along with the CCS method and power supply capability.
