Lawson criterion, Physics

Lawson criterion (J.D. Lawson):

A situation for the release of energy from a thermonuclear reactor. Usually it is stated as the minimum value for the product of the density of the fuel particles & the energy confinement time for energy breakeven. For half-&-half mixture of deuterium & tritium at ignition temperature, nG tau is among 1014 and 1015 s/cm3.
