ITER - The World's Largest Tokamak
ITER is based on the 'tokamak' concept of magnetic confinement, in which the plasma is contained in a doughnut-shaped
. The fuel - a mixture of Deuterium and Tritium, two isotopes of Hydrogen - is heated to temperatures in excess of 150 million°C, forming a hot plasma. Strong magnetic fields are used to keep the plasma away from the walls; these are produced by superconducting coils surrounding the vessel, and by an electrical current driven through the plasma.
