Overview of plasma-tungsten surfaces interactions on the divertor test sector in WEST during the C3 and C4 campaigns
Abstract
Erosion/redeposition pattern was determined on the divertor of WEST. Transport of impurities occurs inside the vacuum vessel towards the HFS. Deposits of >10 µm containing C, B, W, Cu, Fe, O, D were found. 27 % of the tungsten monoblocks had cracks at the end of the C4 campaign.
