Abstract

An ion trap apparatus is provided. The ion trap apparatus comprises two or more radio frequency (RF) rails formed with substantially parallel longitudinal axes and with substantially coplanar upper surfaces; and two or more sequences of trapping and/or transport (TT) electrodes with each sequence formed to extend substantially parallel to the substantially parallel longitudinal axes of the RF rails. The two or more RF rails and the two or more sequences of TT electrodes define an ion trap. The two or more sequences of TT electrodes are arranged into a number of zones. Each zone comprises wide matched groups of TT electrodes and at least one narrow matched group of TT electrodes. A wide TT electrode is longer and/or wider in a direction substantially parallel to the substantially parallel longitudinal axes of the RF rails than a narrow TT electrode.

First claim

That which is claimed:

1. An ion trap apparatus comprising:
at least two radio frequency (RF) rails; and
two or more sequences of trapping and/or transport (TT) electrodes with each sequence formed to extend substantially parallel to at least a portion of the at least two RF rails, the at least two RF rails and the two or more sequences of TT electrodes defining at least a portion of an ion trap,
wherein the two or more sequences of TT electrodes comprises a first electrode and a second electrode, the first electrode and second electrode being different from one another in at least one of size or shape.

2. The ion trap apparatus of claim 1 , wherein the first electrode and the second electrode being different from one another in at least one of size or shape comprises a width of the first electrode being wider in a direction substantially parallel to at least a portion of at least two RF rails than a width of the second electrode in the direction substantially parallel to at least a portion of at least two RF rails.

3. The ion trap apparatus of claim 1 , wherein the ion trap is one of a one-dimensional ion trap or a two-dimensional ion trap.

4. The ion trap apparatus of claim 1 , wherein the two or more sequences of TT electrodes are organized into zones based at least in part on the size or shape of the TT electrodes.

5. The ion trap apparatus of claim 4 , wherein the first electrode and the second electrode are in a same zone.

6. The ion trap apparatus of claim 1 , wherein the two or more sequences of TT electrodes are arranged into matched groups, the first electrode and the second electrode being in different matched groups.

7. The ion trap apparatus of claim 1 , wherein the two or more sequences of TT electrodes are configured to be operated so as to cause an ion within the ion trap to be transported along at least a portion of a confinement region, the confinement region extending substantially parallel to the at least two RF rails.

8. An ion trap apparatus comprising:
a one or more first radio frequency (RF) rails;
a first set of two or more sequences of trapping and/or transport (TT) electrodes with each sequence formed to extend substantially parallel to at least a portion of the one or more first RF rails;
a one or more second RF rails; and

13. The ion trap apparatus of claim 12 , wherein the action is performed by at least one of (a) applying at least one manipulation signal to the at least one ion or (b) interacting the at least one ion with another ion within the at least one action zone.

14. The ion trap apparatus of claim 10 , wherein the plurality of zones comprises at least one intermediary zone, the at least one intermediary one configured for stabilizing at least one ion within the intermediary zone during a transport operation of the at least one ion.

15. An ion trap apparatus comprising:
