2-D hydrodynamical simulations have been used to study the effects of surface finish on the evolution of planar analogs for the components of indirect driven ICF targets (cavity surfaces and capsules), when exposed to the same uniform, assigned, temporally-profiled thermal radiation bath. In this paper the results for the evolution of 300 Angstrom initial perturbation amplitude are presented and shown to be typical of the results obtained for other amplitudes. The simulations show the onset of fast growing hydrodynamical unstable modes, both on the capsule surface and on the cavity surface, producing dramatic effects on symmetry and radiation confinement.
