abstract = {The electron beam device JUDITH 1 was used to establish a
testing procedure for the qualification of tungsten as
plasma facing material. Absorbed power densities of 0.19 and
0.38 GW m−2 for an edge localized mode-like pulse duration
of 1 ms were chosen. Furthermore, base temperatures of room
temperature, 400 °C and 1000 °C allow investigating the
thermal shock performance in the brittle, ductile and high
temperature regime. Finally, applying 100 pulses under all
mentioned conditions helps qualifying the general damage
behaviour while with 1000 pulses for the higher power
density the influence of thermal fatigue is addressed. The
investigated reference material is a tungsten product
produced according to the ITER material specifications. The
obtained results provide a general overview of the damage
behaviour with quantified damage characteristics and
thresholds. In particular, it is shown that the damage
strongly depends on the microstructure and related
thermo-mechanical properties.},
