Modeling of plasma breakdown conditions in ITER
In this paper the mathematical model of optimization of control parameters of the initial plasma stage in ITER is considered. To create conditions for breakdown of plasma and raising its current (in accordance with a specified scenario) control system is required, which allows control parameters to influence the electromagnetic conditions in the chamber of the tokamak. The voltages in the active poloidal coils, the initial currents in the coil and ballast resistance in the coil with a resistor are considered as the control parameters. The control is performed in accordance with technological limitations and physical requirements.
