概要	By using a simulation code for ion-solid interactions, EDDY, the dynamical behavior of W surfaces irradiated simultaneously with H+ and C+ impurity has been studied. This code models the fluence evolution of composition changes between C and W at the irradiated surface, which results from sputtering erosion and impurity deposition. The result has been described in terms of C impurity concentration in the irradiation. It has been compared with experimental data obtained by an ion beam irradiation device. In particular, the C impurity concentration has an important role in erosion/deposition at the W surface. As the C impurity concentration increases, the erosion is enhanced. ing fluence. This results from a growth of a local peak at around a depth of 20 nm in the depth profile of the deposited C.
