“The man who moves a mountain begins by carrying away small stones.” – Confucius
At 1 a.m. on the morning of December 5, 2022, the National Ignition Facility (NIF) had a significant breakthrough: the inertial confinement of a compressed target was just good enough to initiate thermonuclear burn. For the first time, humanity achieved net gain from a controlled fusion reaction within a laboratory; the lasers delivered 2.05 MJ of energy, resulting in 3.15 MJ of fusion energy output. This achievement—over in the blink of an eye (tens of nanoseconds)—was the result of over two decades of work on NIF, six decades after John Nuckolls conceived of the possibility of laser-driven inertial confinement fusion (ICF). We congratulate our current and former colleagues across the Lab for this tremendous achievement. Read more...
