Density and temperature sensitive features in high temperature plasmaL-shell xenon emission spectra

We present model calculations demonstrating new density and temperature sensitive ratios of groups of F- and Ne-like Xe lines which are suitable for diagnosing plasma conditions. The method is illustrated by using L-shell Xe emission to infer ${\mathit{T}}_{\mathit{e}}$ in the fuel region of indirectly driven plastic capsules filled with deuterium and doped with 0.1% Ar and 0.02% Xe. The technique uses tractable atomic models and appears scalable to other Ne-like ions.
