Abstract: Tungsten is the wall material for the fusion reactor ITER in France. Hydrogen is the major fuel for the fusion reaction due to its abundance on Earth. Collisions of deuterium with the walls result sputtering, reflection, transmission, and structure manipulations on the target. In this study, we introduce the interactions between the Tungsten layer bombarded with Deuterium atoms at energy values 700 eV and 800 eV with varying angles by employing the binary collision approximation (BCA) model. The collisions between the Tungsten target and Deuterium atoms are simulated separately for different angles from 0 ˚ to 89 ˚. The number and the average energies of backscattered and excavated atoms are investigated to enhance the tungsten wall constructions.
