Abstract
Measurements of radiation heat transport in germanium foils have been made to validate calculations of the radiative opacity of the heated m aterial. Thin germanium foils were indirectly heated to a temperature of 150 eV using thermal x radiation from a laser-produced gold plasma. Emission from the rear surface of the foils was recorded using a stre aked soft-x-ray imaging diagnostic, and the measured radiation-burnthr ough times were compared with hydrodynamic code simulations using tabu lar opacities from the imp code (S. J. Rose, J. Phys. B 25, 1667 (1992 )]. The IMP opacities are validated to better than +/- 50% accuracy.
