Laser Blazes New Milestone Toward Self-Sustaining Fusion Energy
LIVERMORE, Calif., Feb. 3, 2022 — Scientists at Lawrence Livermore National Laboratory’s National Ignition Facility (LLNL NIF) said that, for the first time, physicists have engineered and tested a laser system in which fusion itself — as opposed to external heating...
LLNL Experiment Reaches Threshold of Nuclear Fusion Ignition
LIVERMORE, Calif., Aug. 17, 2021 — An experiment at the Lawrence Livermore National Laboratory (LLNL) National Ignition Facility (NIF) has triggered ignition for the first time. Ignition is the process that amplifies energy output from nuclear fusion and that could provide an avenue...
Deep Learning Bolsters Laser-Driven Ion Acceleration Study
LIVERMORE, Calif., June 3, 2021 — Researchers at Lawrence Livermore National Laboratory (LLNL) have applied neural networks to the study of high-intensity short-pulse laser-plasma acceleration, specifically for ion acceleration from solid targets. In most instances, neural networks...
Lawrence Livermore National Lab Names Kim Budil Director
LIVERMORE, Calif., Feb. 8, 2021 — Lawrence Livermore National Laboratory’s (LLNL) new director, Kim Budil, will begin her new role March 2. Budil, replacing Bill Goldstein, will serve as the laboratory’s 13th director. She is the first female director in the...
National Ignition Facility Sets New Laser Energy Record
LIVERMORE, Calif., July 10, 2018 — Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) laser system has set a new record, firing 2.15 MJ of energy to its target chamber. This is a 15 percent improvement over NIF’s design specification of 1.8...
