Numerical Simulations for Re-emission of Au Planar targets

One-dimension multi-group radiation transfer program was used to simulate the processes of re-emission for Au disk. Some results about the re-emission spectrum, the re-emission flux, the albedo and the equivalent temperature at the boundary are given, and the variations of re-emission spectrum with the incident flux are analyzed. It is found that the re-emission spectrum is closely related with the depth of ablation and the optical thickness of corona plasma.
