Abstract
A miniature electrode apparatus is disclosed for trapping charged particles, the apparatus includes, along a longitudinal direction, a first end cap electrode, a central electrode having an aperture, and a second end cap electrode. The aperture is elongated in the lateral plane and extends through the central electrode along the longitudinal direction and the central electrode surrounds the aperture in a lateral plane perpendicular to the longitudinal direction to define a transverse cavity for trapping charged particles. Electric fields can be applied in a y-direction of the lateral plane across one or more planes perpendicular to the longitudinal axis to translocate and/or manipulate ion trajectories.
