Phys. Rev. Lett. 94, 045002 (2005) [4 pages]Experimental Benchmark for an Improved Simulation of Absolute Soft-X-Ray Emission from Polystyrene Targets Irradiated with the Nike LaserSee Also: Publisher's Note Received 22 October 2004; published 3 February 2005; corrected 23 February 2005 Absolutely calibrated, time-resolved spectral intensity measurements of soft-x-ray emission (hν∼0.1–1.0 keV) from laser-irradiated polystyrene targets are compared to radiation-hydrodynamic simulations that include our new postprocessor, Virtual Spectro. This new capability allows a unified, detailed treatment of atomic physics and radiative transfer in nonlocal thermodynamic equilibrium conditions for simple spectra from low-Z materials as well as complex spectra from high-Z materials. The excellent agreement (within a factor of ∼1.5) demonstrates the powerful predictive capability of the codes for the complex conditions in the ablating plasma. A comparison to data with high spectral resolution (E/δE∼1000) emphasizes the importance of including radiation coupling in the quantitative simulation of emission spectra. URL:
