Simulations of Ti-Layered Magnetized Liner Inertial Fusion Implosions on OMEGA Investigating Effect of Mix *

Magnetized liner inertial fusion (MagLIF) on OMEGA is a laser-driven platform used to study magneto-inertial fusion. Simulations of fully integrated MagLIF implosions describe a trend of decreasing DD neutron yields with increasing laser preheat energy, but overpredict the yield compared to experiments. To investigate the effect of mix, the experiments were performed with a capsule that included a Ti layer on its inner wall, and these experiments showed large yield degradation. Simulations with HYDRA were done for OMEGA MagLIF configurations with and without Ti layer and with varying fraction of Ti premixed into the fuel region. In simulations, the modeling of Ti layer alone does not reproduce the yield drop in experiment. Only simulations with Ti mixed in the fuel show the large yield drop indicating the importance of mix effects in OMEGA MagLIF.
