Title (EN) METHOD AND APPARATUS FOR GENERATING PARTICLE BEAMS
(FR) PROCEDE ET APPAREIL DE PRODUCTION DE FAISCEAUX DE PARTICULES
Abstract: front page image
(EN)A source of atomic or molecular particles includes a source of ionised particles (1), an extraction electrode (2) and an einzel lens (3) to focus a beam of particles. A Wien filter (4) selects particles in said beam having a predetermined velocity and a charge exchange cell (7) neutralises the ionised particles prior to the extraction of non-ionised particles from the beam.
(FR)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.
