Abstract
At high plasma density we find two types of radiation belts at the edge of the Wendelstein-7AS stellarator. The first one is observed in the inboard scrape-off layer (SOL) when the edge plasma is detached. It seems to be specific to the stellarator. The second one is found on closed flux surfaces and resembles the Marfe phenomenon known from tokamaks. They are experimentally characterized and modeling calculations are presented.
