abstract = {To investigate the performance of stainless steel under
transient thermal events, such as photon pulses caused by
disruptions mitigated by massive gas injection (MGI), the
material has been exposed to electron beam loads with ITER
relevant power densities slightly above the melting
threshold (245 MW/m2) and a pulse duration of 3 ms (Sugihara
et al., 2012; Klimov et al., 2013; Pitts et al., 2013). The
samples were manufactured from different steel grades with
slightly modified chemical composition. To investigate the
effect of repetitive surface heat loads on the melting
process and the melt motion, identical heat pulses in the
range of 100–3000 were applied. All tested materials
showed intense melt-induced surface roughening, driven by
repeated shallow surface melting up to several ten
micrometre and fast re-solidification with epitaxial grain
growth. During the liquid phase, melt motion induced by
cohesive forces results in the formation of a wavy surface
structure with apexes. Further experiments have been
performed to study the effects of non-perpendicular surfaces
or leading edges.},
