%X Microstructured foams are emerging as a promising class of targets, with   applications ranging from laser-driven particle acceleration to inertial   confinement fusion. To unlock their full potential, a deeper   understanding of their properties, especially the changes and behavior   of the microstructure under extreme conditions, is required. While   recently advancing 3D printed foam targets can be observed by X-ray   radiography, the microstructure in chemically produced targets is far   below the spatial resolution of conventional radiography. To overcome   this limitation, we apply grating-based X-ray dark-field imaging to   observe structural changes in foams that are rapidly heated by   laser-accelerated proton pulses. The experimental data is compared to   synthetic dark-field values obtained from hydrodynamic simulations of a   simplified foam model. Both experimental and simulation results   demonstrate the viability of utilizing grating-based dark-field imaging   for observing microstructural changes in foam targets.
