Abstract : The structuring that a LWIR system might detect is addressed in this report. This research was performed by incorporating the results of an analytic study of Rayleigh-Taylor instabilities into a code which tracks the temporal behavior of various plasma quantities. The results indicate that structuring will occur in times less than 5 secs. Estimates of maximum and minimum wavelengths and of growth rates are provided. The structured regions contain sizable concentrations of metallic and oxygen ions and may well present difficulties to LWIR systems depending on the chemical activity present in the structure.
