spallation : Éjection de particules atomiques d'un noyau à la suite de la collision d'un atome et d'une particule de haute énergie (généralement un rayonnement cosmique), qui entraîne la formation d'un isotope différent qui n'est pas un produit (isotope) de fission. 4, record 1, French, - cible%20de%20spallation

Production of neutrons at a spallation neutron source. Generally the production of neutrons at a spallation source begins with a high powered accelerator. This is more often than not a synchrotron. 1, record 2, English, - spallation%20source

Une tentative américaine de construire un réacteur (Advanced Neutron Source) aux limites des possibilités a avorté. Pour aller au-delà, on se tourne donc vers une autre technique : la source à spallation. Celle-ci consiste à arracher des neutrons à des noyaux lourds (Hg, W, Pb, Bi...) au moyen de protons à haute énergie. Il n'est pas indispensable d'utiliser des cibles actinides, qui seraient encore meilleures mais produiraient des déchets bien plus radioactifs. 1, record 2, French, - source%20%C3%A0%20spallation
