Claim Text:
1. An ion trap device, comprising: a plurality of first electrodes having a first RF voltage, each of said first electrodes having an annular shape defining edges of a regular polygonal surface, the plurality of first electrodes being arranged together to form a regular polyhedral structure, the structure encompassing a containment region therein for containing ions, wherein the containment region corresponds substantially to a volume encompassed by the regular polyhedral structure; and a plurality of second electrodes having a second RF voltage, the second RF voltage being of equal amplitude and opposite polarity at a point in time as the first RF voltage whereby the first and second electrodes are maintained at opposite phases, each of said second electrodes being disposed at the center of a polygonal surface defined by a first electrode, such that the plurality of first and second electrodes form a potential barrier for repelling the ions from each of the plurality of regular polygonal surfaces forming the regular polyhedral structure.
