Ion shuttling system with compensation electrodes for ion trap

An apparatus, comprising:

• one or more radio frequency (RF) electrodes connected to an RF generation system and configured to create an RF trapping point and to trap an ion;
• a plurality of first electrodes configured to control movement of an ion along a movement direction by generating an electrical field as a result of being provided with an ion movement control voltage;
• a voltage source configured to provide one or more compensation voltages;
• a plurality of compensation electrodes comprising a plurality of compensation electrode pairs, wherein each compensation electrode pair of the plurality of compensation electrode pairs is associated with a one or more different first electrodes that are of the plurality of first electrodes and that are disposed between compensation electrodes of the associated compensation electrode pair, wherein each compensation electrode pair is configured to provide a compensation electrical field (E-Field) to an ion being shuttled by an associated one or more first electrodes to shift an ion, which is affected by a stray voltage, toward the RF trapping point in response to compensation voltages provided to the compensation electrodes of the compensation electrode pair;
• and
• a plurality of switches, wherein each switch of the plurality of switches is configured to selectively connect a respective compensation electrode of the plurality of compensation electrodes to the voltage source.

A method, comprising:

• identifying one or more compensation electrodes from a plurality of compensation electrodes in an ion movement control system having the plurality of compensation electrodes and a plurality of first electrodes;
• determining a compensation voltage for the one or more compensation electrodes;
• controlling a voltage source to provide the compensation voltage;
• and
• providing the compensation voltage to the one or more compensation electrodes by connecting the one or more compensation electrodes to the voltage source, by at least controlling one or more switches of a plurality of switches to connect the one or more compensation electrodes to the voltage source, while one or more first electrodes of the plurality of first electrodes controls movement of an ion.
