DEVELOPMENT OF BERYLLIUM-COPPER ALLOY IGNITION CAPSULES

摘要

Cu-doped Be capsules are being developed for ignition on the National Ignition Facility (NIF). Our fabrication approach is based on bonding of cylindrical parts containing precision machined hemispherical cavities, followed by machining an external spherical contour to produce a spherical shell. While we have demonstrated this approach, there are several key issues that need to be resolved before a shell meeting NIF specifications can be produced. In this paper we report on the progress that has been made in resolving the key issues.
