Design of ignition targets for the National Ignition Facility

PDF Version Also Available for Download.

Description

This is a brief update on the work being done to design ignition targets for the National Ignition Facility. Updates are presented on three areas of current activity : improvements in modeling, work on a variety of targets spanning the parameter space of possible ignition targets ; and the setting of specifications for target fabrication and diagnostics. Highlights of recent activity include : a simulation of the Rayleigh-Taylor instability growth on an imploding capsule, done in 3D on a 72{degree} by 72{degree} wedge, with enough zones to resolve modes out to 100 ; and designs of targets at 250eV and ... continued below
