In summary, with advanced diagnostic techniques, we are approaching to better understanding of the Rayleigh-Taylor instability. The itemized summary is listed up: 1. Rayleigh-Taylor (RT) is the critical physics for high-gain IFE 2. Energy transport can modify the RT growth at short wavelengths. 3. Moire interferometry first observed the short wavelength RT growth. 4. The observed RT growth suggests that nonlocal transport plays a role in ablative stabilization. 5. For independent test of the transport effect, we are currently measuring the ablation density with high-resolution imaging techniques. 6. Initial test result is favorable to the density measurement. with advanced diagnostic techniques, we are approachingto better understanding of the Rayleigh-Taylor instability. Finally, we emphasize that our strategy is to measure all necessary quantities (growth rates, gravity, wavenumber of the perturbation, mass ablation rate, density profile) to test various theories of the Rayleigh-Taylor instability.
