Optimization approach to solving the problem of start of the discharge in the ITER tokamak

Abstract

In this paper the mathematical problem of optimization of control parameters of the initial plasma stage in ITER is considered. To construct a mathematical model of optimization one used a model of dynamics of the currents in poloidal circuits of tokamak. The aim in the studied optimization problem is the creation of conditions for the breakdown of the plasma, as well as its further development in accordance to a specified scenario of rise of the plasma current at the initial stage.
