The influence of impurities on the erosion of tungsten by low energy high flux deuterium plasma irradiation

The erosion behavior of tungsten (W) exposed to low-energy, high flux deuterium (D) plasma has been investigated. The samples were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM) and ion beam analysis (IBA). The eroded thicknesses increase with increasing irradiati...
