Radiative opacity of gold plasmas studied by a detailed level-accounting method.

Detailed Theoretical Investigations on the L-Shell Absorption of Open-M-Shell Germanium Plasmas:Effect of Autoionization Resonance Broadening

Radiative opacity of open-M-shell germanium plasmas in the L-shell photon energy region were investigated in detail by using a fully relativistic detailed level accounting approach. Among other physical effects such as relativistic and the interaction between fine-structure levels belonging to the same non-relativistic configuration and different configurations, particular attention is paid on ...

Experiments and simulations on the possibility of radiative contraction/collapse in the PF-1000 plasma focus

The possibility of radiative collapse in pinched linear discharges was fi rst studied independently by Pease [1] and Braginskii [2] in 1957 for pure hydrogen or deuterium plasmas. When radiation losses by bremsstrahlung exceed Ohmic heating at high currents, they predicted shrinking of the plasma column, which may even result in a collapse of the column to extremely high densities. They derived...

Ionization competition effects on population distribution and radiative opacity of mixture plasmas

Atomic and optical properties of warm dense copper.

The emission of x rays from warm dense matter is of great interest for both spectroscopic diagnostics and development of intense x-ray sources. We report the results from the collisional-radiative steady-state (CRSS) modeling of atomic and optical properties of copper plasmas at near-solid and solid-state density for a range of temperatures. The CRSS model is validated against the available dat...

Analysis of the influence of the plasma thermodynamic regime in the spectrally resolved and mean radiative opacity calculations of carbon plasmas in a wide range of density and temperature

In this work the spectrally resolved, multigroup and mean radiative opacities of carbon plasmas are calculated for a wide range of plasma conditions which cover situations where corona, local thermodynamic and non-local thermodynamic equilibrium regimes are found. An analysis of the influence of the thermodynamic regime on these magnitudes is also carried out by means of comparisons of the resu...
