LIFE, short for Laser Inertial Fusion Energy, was a fusion energy effort run at Lawrence Livermore National Laboratory between 2008 and 2013. LIFE aimed to develop the technologies necessary to convert the laser-driven inertial confinement fusion concept being developed in the National Ignition Facility (NIF) into a practical commercial power ...
10-beam NIR and frequency-tripled 351 nm UV laser; fusion yield of 10 13 neutrons; attempted ignition, but failed due to fluid instability of targets; led to construction of NIF: 1.3 PW: 120 kJ: 30 J: Livermore: LLNL: ISKRA-5: Operational-1989: 12-beam iodine gas laser, fusion yield 10 10 to 10 11 neutrons [93] 100 TW: 30 kJ: 0.3 J: Sarov: RFNC ...
This corresponds to a "fusion gain" —the ratio of input laser power to output fusion power— of about 5. If one uses the baseline assumptions for the current HiPER design, the two lasers (driver and heater) produce about 270 kJ in total, yet generate 25 to 30 MJ, a gain of about 100. [ 10 ]
The 10 beam LLNL Nova laser, shortly after its completion in 1984.In the late 1970s and early 1980s the laser energy per pulse delivered to a target using inertial confinement fusion went from a few joules to tens of kilojoules, requiring very large scientific devices for experimentation.
A NIF fusion shot on September 27, 2013, produced more energy than was absorbed by the deuterium–tritium fuel. [120] This has been confused with having reached "scientific breakeven", [121] [122] defined as the fusion energy exceeding the laser input energy. [123] Using this definition gives 14.4 kJ out and 1.8 MJ in, a ratio of 0.008. [120]
In November 2022, Nakamura co-founded Blue Laser Fusion, a commercial fusion company, with Hiroaki Ohta, a former president of Tokyo-based drone maker ACSL. [26] In July 2023, Blue Laser Fusion raised $25 million from venture capital firm JAFCO Group and the Mirai Creation Fund, which is backed by Toyota Motor and other investors and managed by ...
The Electra KrF laser demonstrates 90,000 shots over 10 hours, a repetition rate needed for an IFE power plant. [1] Inertial Fusion Energy is a proposed approach to building a nuclear fusion power plant based on performing inertial confinement fusion at industrial scale. This approach to fusion power is still in a research phase.
Livermore started its laser fusion program in 1962-63 [11] and began to greatly expand its inertial fusion program in the early 1970s as the first high-power lasers became available. In 1975, Nuckolls was promoted to become the Associate Leader of the Laser Fusion Program, as well as the Divisional Leader of the "X-group" that designed the fuel ...
