Dynamics of ruthenium mirror under action of soft x-ray ultrashort laser pulse

We investigate behavior of the ruthenium targets under x-ray. In this paper, the two-temperature equation of state for Ru is developed. Electronic spectrum of ruthenium is calculated using density functional theory. We have defined an electron-ion coupling parameter of ruthenium and its two-temperature thermal conductivity. With this input we run our two-temperature hydrodynamic code.
