Abstract
This paper reports on the first post-mortem analyses of
tiles removed from JET after the first campaigns with the
ITER-like wall (ILW) during 2011-12 [1]. Tiles from the
divertor have been analysed by ion beam analysis
techniques and by secondary ion mass spectrometry to
determine the amount of beryllium deposition and
deuterium retention in the tiles exposed to the
scrape-off layer. Films 10-20 µm thick were present at
the top of tile 1, but only very thin films (<1 µm) were
found in the shadowed areas and on other divertor tiles.
The total amount of Be found in the divertor following
the ILW campaign was a factor of ~ 9 less than the
material deposited in the 2007-09 carbon campaign, after
allowing for the longer operations in 2007-09.
