Measuring and simulating ice–ablator mix in inertial confinement fusion

Fuel–ablator mix has been established as a major performance degrading effect in the burning plasma regime of recent inertial confinement fusion (ICF) experiments. As such, study fuel–ablator with experiments and simulations can provide valuable insight for our understanding these establish path even higher yields increased robustness. We present novel high-yield experimental ICF design that is motivated by measuring ice–ablator CH ablator instead high-density carbon (HDC) [B. Bachmann et al., Phys. Rev. Lett. 129, 275001 (2022)]. review more detail describe modeling assumptions parameters used to obtain agreement data from implosion burn mix. Using this model calibrated posteriori data, we an uses predicted achieve better than experiment achieved net target gain 1.5 HDC. Because hydrodynamic instabilities are greatly reduced new design, also expect high reproducibility at same adiabat current record yield
