Copper-doped beryllium is one of the leading candidate ablator materials for ignition targets for the National Ignition Facility. Beryllium-ablator designs have been predicted to show reduced sensitivity to hydrodynamic instability growth, and to allow lower drive temperatures to be used, minimizing the effects of laser-plasma instabilities. In initial experiments on the Nova laser designed to investigate Be as an ablator option, we imploded capsules consisting of 38 μm of Cu-doped Be sputter-coated onto 2-μm-thick glass mandrels containing 50 atmospheres of DH mixture. The implosions were driven by a 1-ns-square pulse of Nova containing 19 kJ total energy. In this paper we discuss the experimental data, which included primary neutron yield, x-ray spectra, and core x-ray images from several lines of sight during the implosion. We also discuss comparisons with modeling results that assume the performance was affected by loss of fuel prior to the shots, or by short wavelength Rayleigh-Taylor instability growth.
