Abstract
The implosion dynamics of a hollow cylindrical neon gas‐puff plasma are investigated using a 1‐D non‐local thermodynamic equilibrium radiation hydrodynamic model. Two cases are considered: the implosion of the gas puff with and without a low‐density central core plasma. It is shown that the implosion efficiently converts the kinetic energy of runin into radiation and that the radiation plays a significant role in the implosion energetics. For each case, the history of the implosion dynamics and emission spectra are presented as well as the distribution of radiative energy in the L and K shells. Finally, a comparison is made with purely hydrodynamic calculations.
