Toroidal chamber with magnetic coils (Tokamak)

Toroidal installation for the magnetic retention of plasma in order to achieve the conditions necessary for the flow of controlled thermonuclear synthesis. Plasma in the tokamak is carried out not by the walls of the chamber, which are not able to withstand the temperature necessary for thermonuclear reactions, but a specially created combined magnetic field - a toroidal outer and poloidal field flowing through the plasma cord. Compared to other installations that use a magnetic field for retention of plasma, the use of electric current is the main feature of the tokamak. Plasma current ensures plasma warming up and retention of a plasma cord equilibrium in a vacuum chamber.
