Abstract
The investigation of the erosion process of plasma facing material under plasma irradiation is an important issue for the achievement of the steady-state operation of nuclear fusion devices. Although binary-collision-approximation-based (BCA) simulation is a powerful tool for the investigation of plasma-material interaction, there is a difficulty to apply the simulation to the investigation of dynamical process of erosion because BCA simulation neglects two physical processes, i.e., diffusion process of retained plasma particles in material and structural relaxation process of material. In this paper, therefore, we develop an extended BCA simulation taking account of diffusion and relaxation processes for the calculation of erosion of materials under plasma irradiation.
