The requirement for the energy produced by fusion in a plasma to exceed that required to produce the confined plasma; it states that for a mixture of deuterium and tritium in the temperature range from 1 x 10 exponent 8 degrees Celsius, the product of the ionic density and the confinement time must be about 10 exponent 14 seconds per cubic centimeter. 2, record 1, English, - Lawson%20criterion

Condition qui doit être satisfaite dans le cœur d'un réacteur à fusion pour qu'une réaction thermonucléaire puisse se maintenir : la puissance libérée par le plasma doit être supérieure ou au moins égale à la puissance totale perdue par différents mécanismes (rayonnement de freinage, neutrons, etc.). C'est une inégalité liant la densité et la température du plasma à la durée de vie des particules. 2, record 1, French, - crit%C3%A8re%20de%20Lawson

Le critère de Lawson. [...] Les principaux paramètres agissant sur le bilan d'énergie [d'un plasma où l'on cherche à amorcer la fusion thermonucléaire] sont la densité de particules n, la température T et le temps de vie de l'énergie «tau». Le physicien britannique J.D. Lawson fut [...] le premier à exprimer la condition simple qui relie n, «tau» et T pour que le bilan énergétique soit positif. 3, record 1, French, - crit%C3%A8re%20de%20Lawson
