Title (EN) GENERATION OF COMBINATION OF RF AND AXIAL DC ELECTRIC FIELDS IN AN RF-ONLY MULTIPOLE
(FR) GENERATION D'UNE COMBINAISON DE CHAMPS ELECTRIQUES RF ET C.C. AXIAUX DANS UN MULTIPOLE UNIQUEMENT RF
Abstract: front page image
(EN)An RF-only multipole includes a spiral resistive path formed around each multipole rod body. RF voltages are applied to the rod body and resistive path, and DC voltages are applied to the resistive path, to create a radially confining RF field and an axial DC field that assists in propelling ions through the multipole interior along the longitudinal axis thereof. In one implementation, the resistive path takes the form of a wire of resistive material, such as nichrome, which is laid down in the groove defined between threads formed on the rod body. The RF-only multipole of the invention avoids the need to use auxiliary rods or similar supplemental structures to generate the axial DC field.
(FR)L'invention concerne un multipôle uniquement RF comprenant un trajet résistant en spirale formé autour de chaque corps de tige multipôle. Les tensions RF sont appliquées au corps de tige et au trajet résistant, et des tensions C.C. sont appliquées au trajet résistant, afin de créer un champ RF confiné radialement et un champ C.C. axial qui facilite la propulsion d'ions à travers l'intérieur du multipôle le long de son axe longitudinal. Dans l'une des applications de cette invention, le trajet résistant prend la forme d'un câble de matériau résistant, tel que du nichrome, qui est déposé dans la rainure définie entre les filetages formés sur le corps de la tige. Le multipôle uniquement RF de l'invention ne nécessite pas l'utilisation de tiges auxiliaires ou de structures supplémentaires similaires afin de générer le champ C.C. axial.
