Abstract : The conclusions from the quantitative exploration and generalization of the core-corona model of imploding plasma load dynamics performed over the past 12 months is presented. Several modifications to the original core-corona model were examined as a means to a more physical treatment of the energy transfer between the two regions. The core-corona model arises from four physical considerations, all interrelated. The interrelations among these four assumptions represent time-dependent tests of the model's viability. The model has shown some ability to predict the collapse radii and temperatures with an order-of-magnitude accuracy. With the inclusion of the improved opacity model, very appropriate radiation pulsewidths and amplitudes are also produced, first by the zero-D model and code and now by the 1-D version. The small, fast computer program also makes predictions concerning the time-dependent current partition between core and corona.
