Research on plasma shows very active development, since Langmuir has reported the fundamental study about ionization gases. The study of mechanism which release nuclear fusion energy as lasting energy resource for humanity has come to be very interesting subject because it is in field of high temperature plasma. The paper describes about instrumentation of thermo nuclear fusion reactor which is the main subject of study.
