Abstract
An ion manipulation device comprises a plurality of electrode rings arranged longitudinally adjacent to each other and defining a central axis therethrough. At least one electrode ring comprises a plurality of electrodes arranged in a first planar pattern. Electrodes are configured to periodically receive a voltage to generate a circular traveling wave that rotates around the electrodes of each electrode ring to confine ions within an interior of the apparatus.

An ion manipulation device comprising:
- a plurality of electrode rings arranged longitudinally adjacent to each other and defining a central axis therethrough;
- at least one electrode ring comprising a plurality of electrodes arranged in a first planar pattern;
- wherein the plurality of electrodes are configured to periodically receive a voltage to generate a circular traveling wave that rotates around the electrodes of the at least one electrode ring to confine ions within an interior of the apparatus.
An ion manipulation device comprising:
- a first surface and a second surface positioned parallel to and spaced apart from each other and defining a central axis therebetween;
- outer arrays of electrodes coupled to each of the first and second surface;
- and
- an inner array of electrode rows positioned between the outer arrays of electrodes;
- wherein at least one electrode row comprises a plurality of adjacent electrodes;
- and wherein the electrodes of at least one electrode row are configured to periodically receive a voltage to generate a rotating traveling wave that rotates around the electrodes of the at least one electrode row on the first surface and a corresponding electrode row on the second surface to confine ions between the first surface and the second surface.
A method of manipulating ions comprising:
- injecting ions within an interior of an apparatus comprising a plurality of electrode rings arranged longitudinally adjacent to each other and defining a central axis therethrough, wherein at least one electrode ring comprises a plurality of electrodes arranged in a first planar pattern;
- and
- applying a periodic voltage to at least two electrodes of at least one electrode ring to generate a circular traveling wave that rotates around the electrodes of each electrode ring to confine ions within the interior of the apparatus.
A method of manipulating ions comprising:
