Abstract:

Using nonuniform laser illumination on flat targets, with moderate laser energies 200J, we have produced enhanced density scalelengths e.g., in excess of 0.5 mm at 0.1 of critical density. These enhanced scalelengths are of interest in simulating large, high-gain pellets, and investigating the potential impact of longer scalelengths on a variety of convective plasma instabilities. The non-uniform laser irradiation also affects the spontaneous magnetic fields. These fields were measured for the first time using the Zeeman effect. Space-and-time-resolved measurements, for both polarizations, were made of the 2271-2278 A CV triplet emission. A comparison with theory gave fields around 200 kG. Author
