Figure 6

(a) An illustration of the inhomogeneities in the electric field experienced by a trapped ion packet in a closed, cylindrical ICR cell. When the ions follow the cyclotron orbit close to the middle of the cell (trajectory I), they are subjected to nearly hyperbolic electric potential. As the axial and magnetron components start to contribute ions travel through highly inhomogeneous electric field (for example, trajectory II), which perturbs the motion further increasing the magnetron component. The orbits are not drawn to scale. (b) A schematic representation of the ions being temporally positioned in the center of the cell as consequence of the superimposition the cyclotron and magnetron orbits. The figure is not drawn to scale.
