Abstract
Radio frequency ion traps which consist of periodical sequence of circular orifices are considered. It is shown that by changing the phase shift for the radio frequency voltages applied to neighboring electrodes from its classical value 180° to a new value 90°, the parasitic local pseudopotential minima and corresponding charge particle trapping regions can be eliminated. The latter can significantly improve the effectiveness of conveying of charged particles by the radio frequency ion traps with ring electrodes used as the ion guides and ion storage devices.
