An ion guide having a plurality of spheroidal or similarly shaped electrodes is disclosed. The electrodes are arranged in pairs about a central ion flow axis, and an RF voltage is applied in a prescribed phase relation to create an electric field that focuses and radially confines an ion beam. A defocusing effect associated with the electrode shape may be reduced by placement of a separate skirt electrode immediately downstream in the ion path, or by forming the electrodes in a composite structure, whereby the trailing portion of the electrode is fabricated from or coated with an insulative material.

La présente invention concerne un guide d'ions comportant une pluralité d'électrodes sphéroïdales ou de forme similaire. Les électrodes sont disposées par paires autour d'un axe de circulation ionique central, et une tension RF est appliquée dans une relation de phase prescrite pour créer un champ électrique qui focalise et confine radialement un faisceau d'ions. Un effet défocalisant associé à la forme des électrodes peut être réduit en plaçant une électrode de blindage séparée immédiatement en aval dans le chemin ionique, ou en formant les électrodes dans une structure composite, la partie de talonnement de l'électrode étant alors fabriquée en ou revêtue d'un matériau isolant.
