dc.description.abstractThe study of plasma–surface interaction processes is important for a successful realization of the international ITER project. The JET ITER-like wall (ILW) [1] comprises a tungsten (W) divertor and beryllium (Be) main chamber wall thus matching the material configuration planned for ITER. Estimating plasma facing component (PFC) sputtering by plasma ions is an important issue for ITER as erosion determines the life time of PFC, impacts on the tritium retention by co-deposition with Be and leads to an increase of impurities in core plasma and the consequent reduction in fusion plasma performance. For correct calculation of the sputtering yields for PFCs the accurate expression for the sheath electric field must be included. This work represents the review of our previous works devoting to the development of analytical expressions for the sheath electric field taking into account the presence of an oblique magnetic field, secondary electron-electron emission and surface biasing.
