Abstract :
Power flux deposition during ELMs and disruptions needs to be controlled in ITER to avoid damage to the plasma facing components (PFC). In present tokamaks, the power and energy deposited on tiles during ELMs is calculated from the surface temperature measurements which are affected by the presence of deposited layers. The thermal behaviour of deposited layers under high heat load exposure has been investigated and the thermal properties of the layers have been determined from experimental data and modelling results obtained with the CAST3M code.
