The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory conducts inertially confined fusion research using lasers, deuterium (D) and tritium (T). If the plasma created by the lasers can be confined for a sufficiently long period of time causing DT fusion reactions, self-heating caused by the alpha particles from the fusion reactions will accelerate until the process runs away and the plasma ignites in a self-sustaining burn.
This talk will cover work using the new "high-foot" pulse-shape implosion that presently holds the record for fusion performance on the NIF. High-foot implosions are the first facility based fusion experiments to generate more energy from fusion than was invested in the fusion fuel. In these experiments, the yield was amplified by the alpha-particle self-heating process by more than ~2X. While much needs to be done to reach ignition, these new results are encouraging.
