Claim 13:
14. A method of ion accumulation, comprising:
introducing ions into an apparatus for ion accumulation having a first region, a second region adjacent to the first region, and a third region adjacent to the second region;
generating a drive potential within the first region for guiding the ions across the first region in a first direction;
transferring the ions from the first region to the second region with the drive potential;
generating a first electric field within the second region when in a first state for preventing the ions from entering the third region using a segmented electrode which extends axially across the second region, the first electric field including a second drive potential and a gate potential generated by the segmented electrode;
accumulating ions in the second region using the gate potential; and
switching the first electric field generated by the segmented electrode within the second region to a second electric field for guiding the accumulated ions in the first direction toward the third region.
