- This paper reports on the first post-mortem analyses of tiles removed from JET after the first campaigns with the ITER-like Wall (ILW) [1]. Tiles from the divertor have been analysed by the Ion Beam Analysis (IBA) techniques Rutherford Back-scattering (RBS) and Nuclear Reaction Analysis (NRA) and by SIMS to determine the amount of beryllium deposition and deuterium retention in the tiles exposed to the scrape-off layer. Films 10-20 microns thick were present at the top of Tile 1, but only very thin films (<1 micron) were found in the shadowed areas and on other divertor tiles.
