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