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 U.S. Department of Energy (DOE) and DOE’s 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 ...

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.

Achieving ignition—producing more fusion energy than the amount of laser energy delivered to the NIF target—provides new opportunities for stockpile stewardship applications; NIF’s recreation of extreme environments allows scientists to study the behavior of materials under weapons-relevant conditions that were previously impossible to ...

The monumental, first-ever demonstration of fusion ignition by Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) marks a potentially world-changing breakthrough for fusion energy and a key initial step in a decades-long quest for limitless clean energy, U.S. government officials and LLNL scientists said Tuesday.

2024年6月20日 · The U.S. Department of Energy (DOE)’s Lawrence Livermore National Laboratory made scientific history on December 5, 2022. An experiment at NIF achieved “target gain,” producing more energy from nuclear fusion (3.15 MJ) than the amount of laser energy delivered to the fusion target (2.05 MJ)—a metric for achieving a robustly ignited ...

2023年12月15日 · In December 2022, after more than a decade of effort and frustration, scientists at the US National Ignition Facility (NIF) announced that they had set a world record by producing a fusion...

The National Ignition Facility (NIF) is the size of a sports stadium—three football fields could fit inside. NIF’s unique energy and power enable cutting-edge research to help keep America safe and secure, explore new frontiers of science, and lay the groundwork for a clean, sustainable source of energy.

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。

2025年3月12日 · In inertial confinement fusion experiments, the fusion device compresses and heats a target to initiate fusion. The biggest of these devices is the National Ignition Facility (NIF) at DOE’s Lawrence Livermore National Laboratory.
