Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

Funding aimed at fusion energy awarded to Laboratory for Laser Energetics, Sandia National Laboratories collaboration

June 30, 2015

The award seeks to build upon recent successes of Sandia’s Magnetized Liner Inertial Fusion (MagLIF) concept. The concept uses a laser to heat fusion fuel contained in a small cylinder as it is compressed by the huge magnetic field of Sandia’s massive Z accelerator.
