Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium ( 2 H) and tritium ( 3 H).
The KrF laser has been used in nuclear fusion energy research since the 1980s. This laser offers several advantages: [7] High rate repetition shots - because the KrF is made using gas it does not heat up, allowing for higher shot rates. Higher beam uniformity; Relatively shorter wavelength for improved ICF compression.
The fusion energy yield of the 2021 experiment was estimated to be 70% of the laser energy incident on the plasma. This result slightly beat the former record of 67% set by the JET torus in 1997. [ 134 ] [ failed verification ] Taking the energy efficiency of the laser itself into account, the experiment used about 477 MJ of electrical energy ...
But as the energy input in a fusion experiment increases, the energy output tends to rise exponentially. An extra 0.15MJ of laser energy, the researchers thought, might just be enough to break the ...
The supposed gain in energy being touted was that 2.05 megajoules of energy went into the laser and 3.15 megajoules were produced. But, as Mark Herrmann, the Livermore laboratory’s program ...
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 ...
The overall efficiency of this approach is many times that of the conventional approach. In the case of NIF the laser generates about 4 MJ of infrared power to create ignition that releases about 20 MJ of energy. [2] This corresponds to a "fusion gain" —the ratio of input laser power to output fusion power— of about 5.
