Ignition is needed to make fusion energy a viable alternative energy source, but has yet to be achieved. A key step on the way to ignition is to have the energy generated through fusion reactions in an inertially confined fusion plasma exceed the amount of energy deposited into the deuterium–tritium fusion fuel and hotspot during the implosion process, resulting in a fuel gain greater than unity. Here we report the achievement of fusion fuel gains exceeding unity on the US National Ignition…

Design of inertial fusion implosions reaching the burning plasma regime
In a burning plasma state1–7, alpha particles from deuterium–tritium fusion reactions redeposit their energy and are the dominant source of heating. This state has recently been achieved at the US
Plasma physics: A promising advance in nuclear fusion
Experiments conducted at the US National Ignition Facility have cleared a hurdle on the road to nuclear fusion in the laboratory, encouraging fusion scientists around the world to develop fusion as a viable alternative energy source.
Burning plasma achieved in inertial fusion
Obtaining a burning plasma is a critical step towards self-sustaining fusion energy1. A burning plasma is one in which the fusion reactions themselves are the primary source of heating in the plasma,

Toward a burning plasma state using diamond ablator inertially confined fusion (ICF) implosions on the National Ignition Facility (NIF)
Producing a burning plasma in the laboratory has been a long-standing milestone for the plasma physics community. A burning plasma is a state where alpha particle deposition from deuterium– tritium
Fusion Energy Output Greater than the Kinetic Energy of an Imploding Shell at the National Ignition Facility.
Time dependent low mode asymmetries that limited further progress of implosions have now been controlled, leading to an increased compression of the hot spot, resulting in hot spot areal density and stagnation pressure never before achieved in a laboratory experiment.
Thermonuclear ignition and the onset of propagating burn in inertial fusion implosions.
It is shown that the transition from hot spot ignition to the onset of propagating burn occurs when the alpha heating within the hot spot has amplified the fusion yield by 15× to 25× with respect to the compression-only case without alpha energy deposition.
