Kalantar et al. at this Conference discuss experiments conducted using the Nova laser at LLNL to investigate material strength stabilization of acceleration-driven instability growth in the solid state. We used a temporally shaped laser pulse to create an x-ray drive inside a cylindrical gold hohlraum to indirectly drive a sequence of shocks that provide a low adiabat compression of a metal foil to a peak pressure of about 3 Mbar while leaving it solid. Considerable attention has been focused on developing the appropriate radiation drive pulse for these experiments. In this presentation we discuss the 2-D hohlraum simulations done with both a radiation-hydrodynamics code and a view factor code to design the nearly adiabatic x-ray drive. Foil trajectory data taken by side-on radiography, radiation temperature measurements taken with a broad band filter x-ray spectrometer, and shock timing measurements taken with a "Michelson" interferometer are compared with simulations in developing our very low isentrope drive.
