Description
In the context of Inertial Confinement Fusion (ICF), micro-structured low-density materials, or foams, have been shown to be able to reduce the effects of hydrodynamic instabilities, while increasing the laser absorption efficiency and enhancing the pressure at the shock front. 3D-printing represents the new manufacturing method for controlling the morphology, gradients in density and pore size, and sample shapes, opening the way to realizing wetted foams.
In this work, the results of experiments in which different kinds of micro-structured materials have been irradiated at the ENEA-ABC laser facility at high intensity of 10$^{14}$ W/cm$^2$ will be discussed. The irradiated samples included chemical, 3D-printed and innovative micro-structured materials. The results of 3D simulations for 3D-printed foams obtained with the FLASH code will be discussed.
