NIF is a laser-based fusion research device at Lawrence Livermore National Laboratory. It achieved scientific breakeven in 2022, after decades of construction and experiments.
NIF is a unique and powerful laser system that can create extreme conditions for nuclear fusion, stockpile stewardship, and high energy density science. Learn how NIF enables cutting-edge research to help keep America safe, secure, and sustainable.
Learn how NIF's 192 lasers create nuclear fusion by heating and compressing a target filled with hydrogen atoms. See the path of a NIF shot from the master oscillator to the target chamber and the components of a NIF target.
On Dec. 5, 2022, a team at LLNL’s National Ignition Facility (NIF) conducted the first controlled fusion experiment to reach scientific energy breakeven, producing more energy from fusion than the laser energy used to drive it. This historic milestone will support NNSA’s Stockpile Stewardship Program and advance clean fusion energy research.
Learn how LLNL achieved fusion ignition at NIF in 2022 and how it advances science and energy. Explore the news, programs, and partnerships of NIF&PS, a leading laser research facility.
In a historic announcement, DOE and LLNL scientists celebrate the first-ever demonstration of fusion ignition at NIF, a milestone for fusion energy and national security. The achievement opens new possibilities for clean energy, nuclear science and stockpile stewardship.
The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) made a significant step toward fusion ignition on Aug. 8, 2021, with a yield of more than 1.3 megajoules. This result opens a new experimental regime for inertial confinement fusion research and supports NNSA's stockpile stewardship mission.
