\def\GWpar{
The basic mission of the tokamak technology is to  \emph{heat} and
\emph{confine} for a sufficiently long time the fusion fuel (deuterium-tritium mixture) up to $\approx$ 100 milions degrees Celsius - a sufficient temperature to fuse these light nuclei into a heavier Helium nucleus and a neutron. At these high temperatures the fuel is in a state of matter called plasma: a collection of ionized nuclei and free electrons. These charged particles are confined by a strong magnetic field. The fusion reaction products have a significantly higher kinetic energy and heat the surrounding plasma. This fusion-generated heating power can then be used for electricity production.}


\def\EXPAT{
Tokamak device \cite{Wesson:2004} used for confining a plasma  in order to achieve thermonuclear fusion for energy production \cite{chen2015introduction}. The three basic components of such a device are 1) a toroidal vacuum chamber with vacuum pumps and gas reservoirs and filling system for achieving low pressures (in the order of at least $10^{-4}$ Pa) and thereby sufficiently mean-free-paths of particles, 2) strong magnetic field coils and associated power supplies (generating magnetic fields of several tesla) for confining charged particles in the toroidal chamber and 3) a transformer with power supplies inducing a an electric field and current in the plasma.
