| Abstract: | We performed an experiment using high-energy protons to characterize in situ the spatial and temporal evolution of a laser-driven shock propagating through a low-Z material. Radiography of the shock
propagating through the low-Z transparent material (Lexan, quartz, diamond) enabled estimation of density under compression.
In order to discriminate the influence of the shocked matter on the protons trajectory, a Monte-Carlo simulation was developed.
This code describes the protons trajectory through the matter, calculating the scattering angle and the loss of energy. |
