Development and verification of mathematical model for halo current in ITER

Confined plasma by magnetic field is appear to be abundant and durable source of energy for future aspects. Tokamak is the most advanced device under controlled condition of magnetic field and current flowing in plasma. The interaction of plasma with vacuum vessel gives halo current following poloidal direction with strong outward magnetic force towards vessel. The vertical disruption events caused by this halo current creates an engineering problem for fusion reactor. Therefore, in this paper, toroidal magnetic field Btor and halo current Ihalo were calculated by mathematical formulation and technique. Since, experimental data has already been got from the EAST experiment, therefore, the aim is to developed and investigate an analytical model and computationally evaluate with theoretical calculations. For this case, vertical disruption events of plasma facing components including the balancing sideways forces due to asymptotic poloidal halo current will be evaluated and examined. The results obtained will be useful for equalizing the simulation and experimental results. The research will be extended to developed new models for other Fusion reactors.
