The features of the interaction of plasma with tungsten castellated target surfaces have been studied under repetitive plasma loads with parameters relevant to ITER ELM. The plasma heat loads lead to a significant erosion of the target, which is accompanied by the separation of tungsten droplets/dust from the target surface. The morphology of the target surface and edges changes due to the crack formation and melt motion depending on the number of plasma pulses. The edges erosion exceeded the erosion of the target central area considerably, and it dominated in the resulting damage of the exposed targets. Product Description popup.authors І.Є. Гаркуша В.В.
