Abstract
Ions are introduced into a Kingdon ion trap in which the ions can oscillate harmonically in a potential well in the longitudinal direction, essentially decoupled from their transverse motion by a Kingdon ion guide, which can consist of a drill-hole through the wall of the ion trap housing electrodes and a central wire. An injection potential is first applied to the wire, but once the heaviest ions of interest have been injected into the trap, the potential of the wire is switched to the potential of the housing electrodes, to trap the ions in the trap. The ions introduced into the Kingdon ion trap may come from a small ion cloud, located in a Paul trap.
