摘要：

The influence of atomic and radiation modeling on the dynamics and energetics of imploding neon gas-puff plasmas is investigated using a one-dimensional nonlocal thermodynamic equilibrium radiation hydrodynamic model. Results using a simplified description of the atomic physics and radiation transport are contrasted with those from a detailed description. Two configurations are considered: an imploding hollow cylindrical gas puff, both with and without a low density central core plasma. It is found that, in both cases, the expanded atomic model simulations predict a larger fraction of the total energy lost to radiation; the radiative efficiency is greater both because of the enhanced L-shell structure and because of greater compressions obtained as a consequence of the enhanced cooling. For each case, the energy history of the implosion and representative emission spectra are presented.
