Magnetized ICF for high yield, reduction of laser energy, and the generalization of the GLP with B field

Magnetized ICF boosts the yield around ignition threshold¹ and can reduce the required laser energy, without changing the capsule configuration, for high-yield implosions.² We show that by increasing the fuel thickness and dopant level, magnetization can boost yield by 40%, in the high-yield regime, while preserving robustness. For robust implosions, yield can be boosted by 70x around ignition. To maximize the reduction of laser energy by magnetization, the dopant level is lowered, and the laser energy can be reduced by 15% while the robustness and yield are preserved. To quantify the magnetized robustness, we modify the Generalized Lawson Parameter (GLP) with the inclusion of B field. Universal ignition conditions with and w/o B field are derived and the amount of velocity reduction from magnetization can then be obtained. New physics findings, e.g., magnetized ignition condition for Ti is higher than the conventional condition of 12 keV, and the design options opened up by magnetization are presented.
