1 An Overview of Erosion-Deposition Pattern in JET with ITER-Like Wall
The aim: To determine material migration and fuel retention by comprehensive ex-situ analyses of PFC and probes retrieved from JET after campaigns. Erosion-deposition diagnostics in JET: Be and W marker tiles, wall probes. Major results: Beryllium is the main element of co-deposits in the divertor. In JET-ILW deposition and fuel inventory are strongly reduced (20x ) in comparison to JET-C. The thickest deposits (15 μm) are on the apron of Tile 1 in the inner divertor. The amount of dust below 2 g, while over 400 g in JET-C. Be and D co-deposition on the divertor Tile 1 in JET-ILW. Comparison of deposition on the divertor Tile 4 in JET-C and JET-ILW. EX/P5-31, Marek Rubel et al.
