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.
- Z machine in Sandia National Laboratories
- 1996 Z machine: 18 MA 100ns
- 2006 ZR (Refurbished): 27MA 95ns
- planned ZN (Z Neutron): 20 and 30 MJ per short
- planned Z-IFE (Z-inertial fusion energy): 70MA 1 petawatt
- fact: As of 2012 Fusion shot simulations at 60 to 70 million amperes are showing a 100 to 1000 fold return on input energy
