Abstract

Source de particules atomiques ou moléculaires comprenant une source de particules ionisées (1), une électrode d'extraction (2) ainsi qu'une lentille symétrique (3) destinée à focaliser un faisceau de particules. Un filtre de Wien (4) sélectionne les particules dans ledit faisceau ayant une vitesse prédéterminée, et une cellule d'échange de charge (7) neutralise les particules ionisées avant l'extraction de particules non ionisées du faisceau.
