Description	Předneseno na:25th IAEA Fusion Energy Conference 2014The original goals for the JET ITER-like Wall included the study of ELM induced tungsten melt events and their impact on plasma operation. Transient tungsten melt experiments were performed in JET using a dedicated divertor module and a sequence of 3MA/2.9T H-Mode pulses with an input power 23MW, a stored energy of 6MJ and regular Type I ELMs. By moving the outer strike point onto a dedicated leading edge the base temperature was raised within 1s to a level allowing transient ELM-driven melting during the subsequent 0.5 s. Almost 1mm of W was moved by 150 ELMs within 7 discharges. Although significant material losses in terms of ejections into the plasma were not observed, there is indirect evidence that some small droplets were released.The impact on the main plasma parameters was minor and no disruptions occurred.These experiments provide unique experimental evidence for the absence of significant melt splashing at transie Předneseno na:25th IAEA Fusion Energy Conference 2014The original goals for the JET ITER-like Wall included the study of ELM induced tungsten melt events and their impact on plasma operation.
