摘要：

Measurements of radiation heat transport in germanium foils have been made to validate calculations of the radiative opacity of the heated material. 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 streaked soft-x-ray imaging diagnostic, and the measured radiation-burnthrough times were compared with hydrodynamic code simulations using tabular opacities from the imp code (S. J. Rose, J. Phys. B 25, 1667 (1992)]. The IMP opacities are validated to better than +/- 50% accuracy.
