Recent experimental results using the Nova laser are reviewed. The experiments primarily address the physics of indirect-drive ICF. These experiments include investigating high-Z plasmas and radiation production, hydrodynamic stability, and high convergence implosions. The high-Z plasma experiments used a variety of targets to study the complex dynamics and ionization physics of high-Z plasmas. In long pulse irradiations of Au disks with 0.35- micron light, X-ray conversion efficiencies greater than 70 percent have been demonstrated. In collaboration with AWE, we have quantitatively measured material mix at an unstable accelerated interface. In other experiments, we have observed growth of modulations due to Rayleigh-Taylor instabilities in accelerated samples. Radiation-driven implosions experiments have demonstrated radial convergences of 30 fold with good agreement with 1-D hydrodynamic simulations. Presently these experiments are limited to about 20 kJ of 0.35-micron light due to damage in the amplifier glass. We are presently installing new amplifier glass which will allow routine, operation at 120 kJ of 1 omega light in a 2.5-ns pulse. In addition, we are significantly increasing our ability to measure and control the laser pulse shape. With these improvements, we will be able to perform high-power pulse-shaped experiments needed for high density implosions.
