C-SHAPED YOKE COIL MASS ANALYZER APPARATUS FOR SEPARATING DESIRED ION SPECIES FROM UNWANTED ION SPECIES IN RIBBON ION BEAMS OF ARBITRARY BREADTH

摘要

The present invention is a C-shaped yoke-coil assembly which operates as a markedly improved mass analyzer device; and is able to achieve at least one identifiable modification (such as an effective separation of dissimilar charged ion species) in an adjacent traveling ribbon-shaped beam. The C-shaped yoke coil assembly offers a commercially useful resolving power; is far easier and less expensive to manufacture; and is quickly positioned, aligned, and operated in comparison to conventionally known mass analyzer devices.
