Leander J. Salzer; Gerald Rivera. Elfrno V. Armijo, and Paul G. Apen, Los Alamos National Laboratory, P.O. Box 1663 MS E549, Los Alamos, NM 87545. The fabrication of the plastic cylinders used in recent cylindrical implosion experiments • at NOVA is presented. Seven steps were required - three machining, three coating, and one leaching - for the successful completion of a single cylinder. The coating steps included polystyrene, chlorinated polystyrene and parylene N. Precision machining was required to produce a marker layer as well as a dodecagonal outside surface. LA-CP-93-118 1 Experiments are needed to study the effects of surface perturbations on Implosions Surface Perturbations of ICF Capsules by Laser Ablation We want to place Known perturbations
