We report measurements of controlled implosion performance degradation arising from the Rayleigh-Taylor instabiity in inertial confinement fusion capsules. Using plastic capsules driven indirectly by the Nova laser we studied the variation in implosion performance as a function of outer surface perturbation. Variations in both capsule x-ray and neutron emission are seen which are consistent with a model which describes mixing of pusher material into fuel material. The model combines representative capsule surface characterization, implosion stability, and perturbation growth saturation.
