Abstract
Accurate descriptions of laser power coupling to the plasma and electron energy transport are crucial for designing shock-ignition targets and assessing their robustness (in particular with regard to laser and positioning errors). To this purpose, the 2D DUED laser fusion code has been improved with the inclusion of a 3D laser ray-tracing scheme and a model for non-local electron transport. 2D simulations with the upgraded code are presented; the dependence of the fusion yield vs target displacement is studied. Two different irradiation configurations are considered.
Highlights
Shock ignition [1] is a recently proposed direct-drive laser fusion scheme
All performed studies were based on simulations with the 2D DUED radiation-hydro-nuclear code [11, 12]
We have introduced in DUED a model for non-local electron transport that replaces the scheme with flux-limited thermal conduction
Summary
