Power flux in the ITER divertor tile gaps during ELMs

Funded under: FP7-EURATOM


In order to withstand strong thermo-mechanical stress in the ITER's divertor, its plasma facing components will be castellated. Consequently, a larger area with complex geometry will be exposed to high fluxes coming from the plasma. In order to evaluate the possible damage caused by transient events, we present here calculations of the expected power loads in the ITER divertor tile gaps during ELMs. We use a self-consistent, two-dimensional particle-in-cell technique to model plasma deposition with realistic boundary conditions. The power loads on the tile surface and inside the gaps are investigated for various magnetic configurations of the strike point and strong plasma parameters.
