Lawson criterion
The Lawson criterion is a concept in fusion science that defines the conditions necessary for a nuclear fusion reaction to be sustained and produce more energy than it consumes. It involves two key factors: maintaining high temperature and density of the fuel, along with sufficient confinement time. In simpler terms, it’s about ensuring that the fuel, like isotopes of hydrogen, is sufficiently compressed, heated, and held together long enough for fusion to occur efficiently. Meeting these conditions is essential for achieving practical and sustainable nuclear fusion as a clean energy source.
