abstract = {Material migration in ITER is expected to move beryllium
(Be) eroded from the first wall primarily to the tungsten
(W) divertor region and to magnetically shadowed areas of
the wall itself. This paper is concerned with experimental
study of Be layer response to ELM-like plasma pulses using
the new QSPA-Be plasma gun (SRC RF TRINITI). The Be layers
(1 → 50 µm thick) are deposited on special castellated Be
and W targets supplied by the ITER Organization using the
Thermionic Vacuum Arc technique. Transient deuterium plasma
pulses with duration ∼0.5 ms were selected to provide
absorbed energy densities on the plasma stream axis for a
30° target inclination of 0.2 and 0.5 MJm−2, the first
well below and the second near the Be melting point. This
latter value is close to the prescribed maximum energy
density for controlled ELMs on ITER. At 0.2 MJm−2 on W,
all Be layer thicknesses tested retain their integrity up to
the maximum pulse number, except at local defects (flakes,
holes and cracks) and on tile edges. At 0.5 MJm−2 on W, Be
layer melting and melt layer agglomeration are the main
damage processes, they happen immediately in the first
plasma impact. Melt layer movement was observed only near
plasma facing edges. No significant melt splashing is
observed in spite of high plasma pressure (higher than
expected in ITER). Be layer of 10 µm thick on Be target has
higher resistance to plasma irradiation than 1 and 55 µm,
and retain their integrity up to the maximum pulse number at
0.2 MJm−2. For 1 µm and 55 µm thick on Be target
significant Be layer losses were observed at 0.2 MJm−2.},
