During the ELM, the time evolution of impact energies of the ions (a) D, (b) Li, and (c) C carried by the ELM, and W physical sputtering yield by the corresponding ions (d) D, (e) Li, and (f) C for nped = 3 × 1019 m−3 at different temperatures in the pedestal region. The black solid line is for Tped = 300 eV, the red dashed line is for Tped = 400 eV, and the blue dot-dashed line is for Tped = 500 eV.
