The National Nuclear Security Administration announced today that scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) have successfully delivered an historic level of laser energy — more than 1 megajoule — to a target in a few billionths of a second and demonstrated the target drive conditions required to achieve fusion ignition. This is about 30 times the energy ever delivered by any other group of lasers in the world.
