National Nuclear Security Administration (NNSA) today (Dec. 13) announced the achievement of fusion ignition at Lawrence Livermore National Laboratory (LLNL) — a major scientific breakthrough decades in the making that will pave the way for advancements in national defense and the future of clean power.

NIF & Photon Science is a principal directorate of Lawrence Livermore National Laboratory (LLNL) in Livermore, California. The facility is funded by the U.S. Department of Energy’s National Nuclear Security Administration (NNSA). The nation’s investments in HED and fusion research pay dividends in our partnerships and tech transfer programs.

2022年12月13日 · On December 5, a team at LLNL’s National Ignition Facility (NIF) conducted the first controlled fusion experiment in history to reach this milestone, also known as scientific energy breakeven, meaning it produced more energy from fusion than the laser energy used to …

The National Ignition Facility (NIF) is a laser -based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain.

2010年1月27日 · The National Nuclear Security Administration (NNSA) announced today that scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) have successfully delivered an historic level of laser energy — more than 1 megajoule — to a target in a few billionths of a second and demonstrated the target drive ...

Because it is the only facility that can create the conditions that are relevant to understanding the operation of modern nuclear weapons, NIF is a crucial element of the National Nuclear Security Administration’s science-based Stockpile Stewardship Program.

On Aug. 8, 2021, an experiment at the National Ignition Facility put researchers at the threshold of fusion ignition, achieving a yield of more than 1.3 megajoules — an 8X improvement over experiments conducted in spring 2021 and a 25X increase over NIF’s 2018 record yield.

2024年1月29日 · Studies using recent ignition experiments indicate an upgrade to 3 MJ of laser energy at NIF could result in fusion output yields in the 30 MJ range. An early stage proposal could turn this idea into reality.

2023年7月30日，美国的国家点火装置（National Ignition Facility，NIF）利用192路激光束向悬浮在腔体内的冷冻氘氚靶丸发射了2.05MJ的能量，最终实现了3.88MJ的聚变能量输出，创造了新的能量输出记录。

The National Ignition Facility (NIF) is an operational multi-megajoule laser facility at Lawrence Livermore National Laboratory (LLNL) in Livermore, CA. In March 2009, construction of NIF was completed and it began full operations.

NIF Transformation and Sustainment FY 2021 was an exceptional year for NIF with ICF experimental results at the threshold of ignition. The achievement creates opportunities to better understand the fundamental processes of fusion ignition and burn and enhance simulation tools supporting stockpile stewardship and modernization.

2022年12月13日 · On Dec. 5, a team at LLNL's National Ignition Facility (NIF) conducted the first controlled fusion experiment in history to reach this milestone, also known as scientific energy breakeven,...

2022年12月13日 · The U.S. Department of Energy (DOE) and DOE’s National Nuclear Security Administration (NNSA) today announced the achievement of fusion ignition at Lawrence Livermore National Laboratory (LLNL) — a major scientific breakthrough decades in the making that will pave the way for advancements in national defense and the future of clean power.

Gordon Brunton is the NIF Director and is responsible for the stewardship of NIF as a premier high energy density experimental facility for the National Nuclear Security Administration (NNSA)’s Stockpile Stewardship Program.

With NIF, scientists will be able to evaluate key scientific assumptions in current computer models, obtain previously unavailable data on how materials behave at temperatures and pressures like those in the center of a star, and help validate NNSA's supercomputer simulations by comparing code predictions against laboratory observations.

2021年8月8日 · By firing its 192 high-energy lasers into a fusion target the size of a pencil eraser, NIF is able to produce temperatures of more than 100 million degrees Kelvin and pressures of hundreds of billions of earth atmospheres—conditions found only in the center of massive stars and in exploding nuclear weapons (see “How NIF Works”).

2021年11月1日 · On August 8, 2021, researchers at the National Ignition Facility (NIF), Lawrence Livermore National Laboratory (LLNL), used 192 laser beams to illuminate the insides of a tiny gold cylinder encapsulating a spherical capsule filled with deuterium-tritium fuel, as they have for many experiments for more than 10 years, in a quest to produce ...

2018年6月20日 · This article, reprinted from the March issue of NNSA’s Stockpile Stewardship Quarterly, describes some of the current NIF inertial confinement fusion (ICF) experiments designed to support the Stockpile Stewardship Program by achieving ignition.

The 10-year plan for NIF, Nikroo said, includes pushing the facility’s performance with its current facility up to 10 MJ output in the near term, and developing an upgrade proposal with NNSA to …
