Abstract
Transmission measurements of warm dense iron plasma are reported over the photon energy range of 400–1200 eV, including the strong 2p–3d structures. One-dimensional hydrodynamic simulation is performed to estimate the plasma conditions: temperatures of several eV and densities of about 0.1 g/cm3. By using the simulated temperature and density, the calculations of the transmission spectra are performed and compared with the time-resolved experimental results.
