"Hydrodynamic simulations of exploding copper foils, which are irradiated on one side by 1.06 micron laser light, indicated that peak axial electron number density is more easily controlled with split-foil target design. Results from a series of simulations with solid copper foils that range in width from 500A to 1500A show that while peak electron temperature and time of burnthrough can be varied, evolved electron number densities are approximately bounded from above by 3 X 10 to the 20th power particles/cc. By increasing foil thickness to 1 micron and introducing aa slit on the foil axis of 100 micron width, uniform plasmas with electron number densities on the order of 6 X 10 to the 20th power particles/cc can be generated. Essentially the same results are obtained from simulations with split selenium foils.
