Manufacturing technology for indirectly driven targets for inertial confinement fusion investigations at the Russian Federal Nuclear Center in Sarov

摘要

This paper reports results on development of the manufacturing technology of targets for experiments on the ISKRA-4 and ISKRA-5 facilities. We describe construction and peculiarities of the fabrication technology for indirectly driven targets with casings of spherical and cylindrical geometry. The central capsule is a glass or polystyrene microsphere filled with a gaseous mixture of DT. In targets with cylindrical casings it can be separated from laser boxes by CH-film partitions. Surface of the central capsule can be covered by layers of metals, parylene, and SiO_2. Also are presented the results for microspheres of glass embedded with europium and lead. A description in given of technologies for filling shells with mixture of DT, Ne, and Ar.
