![]() The cantilevered fill tubes were supported by 12-μm thick SiC rods, offset by 100 μm, 200 μm, and 300 μm from the capsule surfaces. In other experiments, the perturbations from cantilevered fill tubes were measured and compared to the tent perturbations. Subsequent experiments with 3-D perturbations have studied instability growth of 10-μm and 30-μm thick fill tubes to compare them with 30-nm thick tent perturbations at convergence ratios up to ~3. It was calibrated using hydrodynamic growth measurements of pre-imposed capsule modulations with Legendre modes of 60, 90, 110, and 140 at convergence ratios up to ~2.4. A new “sub-scale” version of the existing x-ray radiography platform was more » developed for measuring growing capsule perturbations in the acceleration phase of implosions. After it was recognized that the tents had a significant impact of implosion stability, new support methods were investigated, including thicker, 30-μm diameter fill tubes and cantilevered fill tubes, as described in this article. In NIF implosions, the capsules are supported by tents because the nominal 10-μm thick fill tubes are not strong enough to support capsules by themselves. Hydrodynamic instability growth of the capsule support membranes (or “tents”) and fill tubes has been studied in spherical, glow discharge polymer plastic capsule implosions at the National Ignition Facility (NIF). The mass flux uniformity varied by 50% over the surface of a capsule and varied by 80% over the surface of the bounced pan. The resulting mass-flux distribution to, and around, a capsule quantified the uniformity of the deposition process. The experimentally measured evaporation mass flux of the monomers resulted in a calculated pressure that corresponded to the measured actual value.
