ELM ion energies in the ASDEX Upgrade far scrape-off layer.

摘要

Type I ELMs carry a significant fraction of their energy ?W_(elm) across the scrape-off layer (SOL) and are the dominant source of the first wall thermal load and impurity sputtering. In ITER, ?W_(elm) will be considerably larger compared to present tokamaks and the ELM-wall interaction may be an issue for the first wall lifetime and impurity production.
