Construction and Working Principle of Tokamaks

The tokamak is currently perhaps the most promising route to mastering thermonuclear fusion. It uses a special magnetic cage in the shape of a torus, which can safely isolate the plasma from the walls of the vessel and in which it is possible to increase the temperature of the fuel and finally start thermonuclear fusion. The creation of such a closed reaction space is possible because plasma consists of charged particles, ions and electrons and these are well guided by a magnetic field. Since the launch of the world’s first tokamak in 1958 to the present day, tremendous advances have been made in tokamak research. There are more than fifty working tokamaks in the world today but the largest one, ITER, is still under construction.
