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 ...
Laser beams or laser-produced X-rays rapidly heat the surface of the fusion target, forming a surrounding plasma envelope. Fuel is compressed by the rocket-like blowoff of the hot surface material. During the final part of the capsule implosion, the fuel core reaches 20 times the density of lead and ignites at 100,000,000 ˚C.
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]
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 ]
In 1990, he earned his Ph.D. in physics from the University of British Columbia, focusing on laser fusion. [ 2 ] [ 5 ] Following his Ph.D, Laberge undertook two consecutive postdoctoral research positions, first in 1991 at the École Polytechnique in Paris then at the National Research Council in Ottawa (1992).
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.
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 ...
