US Study Shows Inertial Fusion Implosions Can Tolerate Certain Asymmetries
Researchers at the Lawrence Livermore National Laboratory (LLNL) in the US have recently found that implosion designs for inertial fusion energy (IFE) can withstand considerable imperfections before performance degrades sharply. This result aids in the design of fuel targets for future fusion power plants, particularly in assessing the tolerance of target capsules to errors under high-frequency injection and laser-driven conditions. The study's simulation results show the density (top) and temperature (bottom) at the instant just before fusion reactions peak in an asymmetric implosion. The hottest spot coincides with the point of highest fuel density, indicating direct ignition of high-density fuel jets driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas...
