Hydro-instabilities experiments with alternate capsule support in indirect-drive implosions on NIF*

It was recognized that the tents had a significant impact of implosion’s stability and new alternative support methods were investigated. The tent-less methods included “fishing pole” reinforced fill tubes, cantilevered fill tubes, and thin-wire “tetra cage” supports. Other concepts used “polar tents” and a “foam-shell” to mitigate effects of the tents. These concepts were investigated in x-ray radiography experiments and compared with perturbations from standard tent support. This talk will review and summarize recent results on these alternate capsule support concepts.
