Paper Abstract

We present results from a 1-D plasma dynamics calculation, describing the evolution of strongly heated material in the vicinity of a solid-vacuum interface. We find that the radiation emitted by the hot material in the range hν > kTe, where Te is the initial peak plasma temperature, comes primarily from the region of the original step function interface. This emission is dominated by recombination radiation. The emitted radiation pulse is extremely short; the cooling at the interface is dominated by expansion. It is seen that thermal conduction minimally affects the radiation pulse intensity and duration.
