LLNL simulations calculate ICF’s asymmetry limits
A simulation from the study shows density (top) and temperature (bottom) just before the time when fusion reactions peak in an asymmetric implosion. The hottest point coincides with the densest point of fuel, illustrating the direct ignition of a dense jet of fuel driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas. (Image: LLNL)
Researchers at Lawrence Livermore National Laboratory used simulations to show that inertial fusion power plants could tolerate significant low-mode asymmetries, such as those caused by laser alignment being off-center, revealing a trade-off between robustness and yield that could impact how power plants are brought on line.
The National Nuclear Security Administration is a semi-autonomous agency within the U.S. Department of Energy responsible for enhancing national security. NNSA maintains the U.S. nuclear stockpile; works to reduce the danger from weapons of mass destruction; provides the U.S. Navy with nuclear propulsion; and responds to nuclear and radiological emergencies.
