National Ignition Facility experiment puts researchers at threshold of fusion ignition
Lawrence Livermore National Laboratory

Achieving fusion ignition – the process that powers the sun, stars and thermonuclear weapons – has been a decades-long goal for inertial confinement fusion research. On Aug. 8, 2021, an experiment at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) made a significant step toward ignition, achieving a yield of more than 1.3 megajoules (MJ). This is enabled by focusing laser light from NIF - the size of three football fields - onto a target the size of a BB that produces a hot-spot the diameter of a human hair, generating more than 10 quadrillion watts of fusion power for 100 trillionths of a second. This advance puts researchers at the threshold of fusion ignition, an important goal of the NIF, and opens access to a new experimental regime.
