abstract = {Tungsten, the plasma facing material (PFM) for the divertor
in ITER, must sustain severe, distinct loading conditions.
This broad array of exposure conditions necessitates
comprehensive experiments that cover most of the expected
loading parameters to predict qualitative statements about
the performance and as a consequence thereof the intended
operation time. However, comprehensive experiments are
inherently difficult to realize due to the fact that there
is no device that is capable of simulating all loading
conditions simultaneously. Nevertheless, the linear plasma
device PSI-2 enables experiments combining thermal and
particle exposure at the same time. In this work, sequential
and simultaneous loads on pure tungsten at different base
temperatures were investigated to study not only the
performance of the material, but also the influence of the
experimental parameters. The detailed analysis and
comparison of the obtained results showed different kinds of
damage depending on the loading sequence, power density,
microstructure of the samples, and base temperature.
Finally, samples with transversal grain orientation (T)
showed the weakest damage resistance and the increase of the
base temperature could not compensate the detrimental impact
of deuterium.},
