  <dc:description>This bachelor thesis studies the feasibility of grazing-incidence small-angle x-ray scattering&#13;
(GISAXS) in the UHI laser-target interaction via computational simulations with SMILEI. In&#13;
this work we briefly analyze the front and back of the target. We find predominantly that the&#13;
compression of the target becomes apparent in the GISAXS pattern, while we can not observe&#13;
ablation. We will mainly focus on the density oscillation, a dynamic that has not been mentio-&#13;
ned in literature yet. The density oscillation dynamics depend on a simple pressure gradient&#13;
in between the layers. We observe the multi layers inversely oscillating in density and a global&#13;
density alteration moving through the target. The density alteration allows to recognize the&#13;
dynamic in a GISAXS pattern. We learn, that GISAXS is feasible in the high intensity regime,&#13;
but not for the same dynamics as in the lower intensity regime.</dc:description>
