Sensitivity of ICF ignition conditions to non-Maxwellian DT fusion reactivity

The hotspot ignition conditions in ICF are determined by considering the power balance between fusion energy deposition and energy loss terms. Uncertainty in any of these terms has potential to modify the ignition conditions, changing the optimum ignition capsule design. This paper considers the imp...
