12 Ιουλ 2012 · The NIF laser system of 192 beams delivered more than 500 trillion watts (terawatts or TW) of peak power and 1.85 megajoules (MJ) of ultraviolet laser light to its target. Five hundred terawatts is 1,000 times more power than the United States uses at any instant in time, and 1.85 megajoules of energy is about 100 times what any other laser ...
29 Ιαν 2024 · 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.
A record high-laser-energy NIF target shot on Sept. 19 produced about 1.2 million joules of fusion energy yield. Compared with the groundbreaking 1.35-megajoule (MJ) experiment of Aug. 8, 2021, this experiment used higher laser energy and a modified experimental design.
The National Ignition Facility (NIF) currently under construction at the University of California Lawrence Livermore National Laboratory (LLNL) is a 192-beam, 1.8-megajoule, 500-terawatt, 351-nm laser for inertial confinement fusion (ICF) and high-energy-density experimental studies.
NIF’s laser beams can create nuclear fusion in the laboratory by generating the same kinds of temperatures and pressures that exist in the cores of stars and giant planets and inside nuclear weapons (see Anatomy of a NIF Shot).
With its APT program within NIF, Livermore continues to innovate and lead in the development of next-generation laser architectures with the potential to push petawatt-scale lasers beyond 10 Hz and even up to the kilohertz (kHz) rate (1,000 shots per second).
9 Αυγ 2024 · single laser beam line into a dedicated precision diagnostic system as part of the NIF Early Light (NEL) campaign, setting a world record for laser performance and meeting its primary criteria for ignition.
