These experiments show fusion self-heating in excess of the mechanical work injected into the implosions, satisfying several burning-plasma metrics 3, 8. The burning-plasma state was created using a strategy to increase the spatial scale of the capsule 2, 3 through two different implosion concepts 4, 5, 6, 7. We use the lasers to generate X-rays in a radiation cavity to indirectly drive a fuel-containing capsule via the X-ray ablation pressure, which results in the implosion process compressing and heating the fuel via mechanical work. These experiments were conducted at the US National Ignition Facility, a laser facility delivering up to 1.9 megajoules of energy in pulses with peak powers up to 500 terawatts. After decades of fusion research, here we achieve a burning-plasma state in the laboratory. A burning plasma is one in which the fusion reactions themselves are the primary source of heating in the plasma, which is necessary to sustain and propagate the burn, enabling high energy gain. Obtaining a burning plasma is a critical step towards self-sustaining fusion energy 1.
