abstract = {PFMs (Plasma-facing materials: ITER grade stainless steel,
beryllium, and ferritic–martensitic steels) as well as
deposited erosion products of PFCs (Be-like, tungsten, and
carbon based) were tested in QSPA under photonic heat loads
relevant to those expected from photon radiation during
disruptions mitigated by massive gas injection in ITER.
Repeated pulses slightly above the melting threshold on the
bulk materials eventually lead to a regular,
“corrugated” surface, with hills and valleys spaced by
0.2–2 mm. The results indicate that hill growth (growth
rate of ∼1 μm per pulse) and sample thinning in the
valleys is a result of melt-layer redistribution. The
measurements on the 316L(N)-IG indicate that the amount of
tritium absorbed by the sample from the gas phase
significantly increases with pulse number as well as the
modified layer thickness. Repeated pulses significantly
below the melting threshold on the deposited erosion
products lead to a decrease of hydrogen isotopes trapped
during the deposition of the eroded material.},
