“…Figure 3 shows the simulated temporal behavior of the density and temperature at the center and boundary of the constrained Al sample. The radiation in the Hohlraum was simulated first by a three-dimensional x-ray Monte Carlo transfer code RT3D, 23 then the radiation passing through the CH baffles was simulated by a two-dimensional multigroup transport code LARED-R-1, 24 finally the temperature and density of the radiation-heated Al sample were simulated by one-dimensional multigroups transport code RDMG. 25 It can be seen from the figure that the density and temperature of the sample quickly reach homogeneity.…”

Simultaneous measurements of the self-emission spectrum, the backlighting source spectrum, and the transmission spectrum in one shot, which reduce the experimental uncertainties from shot-to-shot fluctuation, are essential for precise opacity experiments. In order to achieve precise absorption spectrum of Al plasmas, a special half sample sandwich target was designed and short backlighter was used to provide time- and space-resolving diagnostics on the Shenguang II high power laser facility. In the measurement, a cylindrical cavity with CH foam baffles was used to provide a clean x-ray radiation environment for sample heating. The x-ray source spectrum, the transmission spectrum, and the self-emission spectrum of the soft x-ray heated Al sample were recorded in one shot with a penta-erythritol tetrakis (hydroxymethy) methane C(CH(2)OH)(4) (PET) crystal spectrometer by using the point-projection method. Experimental results have been compared with the calculation results of a detailed level accounting opacity code.
