Inertial_confinement_fusion (ICF)
Schematic of the stages of inertial confinement fusion using lasers. The blue arrows represent radiation; orange is blowoff; purple is inwardly transported thermal energy.
- 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.
- Thermonuclear burn spreads rapidly through the compressed fuel, yielding many times the input energy.
Worldwide Installations able to produce ICF
- National_Ignition_Facility at the Lawrence Livermore National Laboratory
- Laser_Megajoule in Bordeaux, France
- Z machine at the Sandia National Laboratories
- 1996 Z machine: 18 MA 100ns
