Towards a complete model of 3D line emission from ICF capsules: results from the first 3D simulations

Hydrodynamic instabilities can reduce the yield in inertial confinement fus ion (ICF) implosions. Line emission from dopants placed in the capsule can be used to diagnose the extent of the instabilities. In earlier work we com pared line emission measured in experiments performed on the Nova laser to one-dimensional mix models and two-dimensional models in which many differe nt instability wavelengths interact. Three-dimensional simulations are requ ired to model properly the saturation of the hydrodynamic instabilities. Th is paper presents the results of the first three-dimensional simulations of line emission from ICF capsules. The simulations show that the three lines considered here come from different spatial regions. Line ratios cannot be used to determine temperatures without accounting for the spatial dependen ce of the line emission. Future papers will present detailed comparisons to experiments.
