The codes have been used in the design of ITER: ITER is intended to prove the viability of fusion as an energy source, and to collect the data necessary for the design and operation of the first fusion power plant.RF plasma device in our laboratory is used to test our codes by comparing the calculated and observed photoemission intensities of the atoms and molecules.RF plasma device in our laboratory.Reaction processes of atoms and molecules.Realizing NuclearFusionEnergyModellingof Hydrogen and Helium in Fusion PlasmaThe most exciting application of plasmas is the production of power from thermonuclear fusion. Fusion plasmas give off large amounts of heat and very energetic particles. However, they damage the surfaces of the reactor walls.The protection of the walls is one of the remaining critical issues for the realization of fusion plants. Neutral atoms and molecules in the near-wall region of fusion plasmas are expected to act as buffers. Thus it is important to understand the reaction processes of these atoms and molecules.
