Radiative Transfer: Plasma
Scientific paper
Recent laser-produced plasma experiments have relied on spectroscopic comparisons with models to infer plasma temperatures. Here, the technique is applied to study thermal radiation transfer experiments. The transmission model combines high-quality atomic data with an ionization balance obtained from systematic expansions of the grand canonical ensemble. The latter avoids the ad hoc cutoffs required in free energy minimization schemes and includes Coulomb corrections usually neglected in other models. It is shown that the improved equation of state significantly effects inferred temperatures at the higher densities expected in the heat flow experiments. Even though good agreement is obtained between the experimental and theoretical transmission spectrum, the experimental uncertainties are sufficiently large that it compromises the intended bench marking of the thermal transport models.
