Particle and energy fluxes to the plasma facing components (PFCs) during edge localized modes (ELMs) are expected to unacceptably shorten the lifetime of PFCs in ITER. Non-linear MHD simulations of ELMs for ITER plasmas, assuming a fluid model for the edge parallel transport, have been made. However, ELM transport in the ITER SOL-divertor plasma is collisionless given the high pedestal plasma temperature. In order to understand the consequences of kinetic effects on the power and particle fluxes to PFCs between ELMs and during ELMs, particle simulations with PARASOL have been carried out for COMPASS H-mode plasmas with two directions of the toroidal field.
