Table 1 Plasma parameters. Summary of different plasma parameters relevant to the flow. The “simulated parameters” are deduced from simulations. They are taken in the foam near the RTI peak at the proximity of the interface. The “calculated parameters” are determined through the formula (in cgs units, amu is the atomic mass unit) using the simulated parameters. Alternative values for the parameters depending on L and u can be found in Table 2, where a more conventional calculation method is used.
