A tokamak is a magnetic confinement device, in which the plasma is contained in a doughnut-shaped vacuum vessel. 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 called Magnets surrounding the vessel, and by an electrical current driven through the plasma. The major components of the tokamak are the superconducting toroidal and poloidal field coils which magnetically confine, shape and control the plasma inside a toroidal vacuum vessel. The magnet system comprises
toroidal field (TF) coils, a central solenoid (CS), external poloidal field (PF) coils, and correction coils (CC).The Vacuum vessel is a double-walled steel structure. There are large structural forces generated in the magnets for which assessment of design is the major part of the project.
