13. During liner implosion, axial convergence associated with sloped electrodes, as well as axial and shear stresses associated with perturbations from the electrodes, set up two-dimensional stresses that propagate throughout the liner. These effects do not have a significant effect on the bulk evolution of the liner when compared with 1D results.
14. The slight difference between the preshot parameters used here and those of the actual experiments have no significant effect on the design of the mounting.
15. The 8° electrode slope in these calculations began about 0.7 mm below the inner edge of the liner. This feature does not effect the initial evolution, but was used in subsequent models of the imploding liner.
