Lawson criterion
(physics) A necessary, but not sufficient, condition for the achievement of sustained release of energy from a nuclear fusion reactor; that the heating effect of the reaction should exceed the losses.
According to the Lawson criterion, the amount of energy needed to heat the D-T fuel to break-even conditions at ambient pressure is perhaps 100 times greater than the energy needed to compress it to a pressure that would deliver the same rate of fusion. Source: Internet
In inertial confinement, both stellar densities and temperatures are exceeded to compensate for the shortcomings of the third parameter of the Lawson criterion, ICF's very short confinement time. Source: Internet
This is also the temperature at which the value of the triple product nTτ required for ignition is a minimum, since that required value is inversely proportional to /T 2 (see Lawson criterion ). Source: Internet
