3D hohlraum model assists in indirect-drive implosions at NIF

July 19, 2021- 
Scientists from Lawrence Livermore National Laboratory (LLNL) and the Laboratory for Laser Energetics (LLE) have described a simple 3D model in hohlraums and capsules for inertial confinement fusion (ICF) implosions. The model will assist in delivering the required implosion symmetry on layered deuterium-tritium (DT) implosions for ignition.  The results of the work remove much of the...

Watching subsurface defects as they move

July 14, 2021- 
A Lawrence Livermore National Laboratory (LLNL) scientist and collaborators have demonstrated the first ever “defect microscope” that can track how populations of defects deep inside macroscopic materials move collectively.
