Assignee: MOBILION SYSTEMS, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An apparatus for ion accumulation, comprising:
a first region configured to receive ions and generate a first drive potential configured to guide the ions across the first region; and
a second region adjacent to the first region, the second region configured to receive the ions from the first region and switch between a first state and a second state, the second region including a segmented electrode which extends axially across the second region, generates a first electric field when the second region is in the first state, and generates a second electric field when the second region is in the second state;
wherein the first electric field includes a second drive potential and a gate potential generated by the segmented electrode, which is configured to accumulate ions in the second region and prevent the ions from entering a third region adjacent to the second region, and the second electric field includes a third drive potential generated by the segmented electrode, which is configured to guide the ions toward the third region, and
wherein when the second region is in the first state the first electric field prevents ions in the second region from exiting the second region back into the first region and causes the ions to accumulate in the second region, and when the second region is in the second state the second electric field causes the ions to move toward the third region.
