Abstract
Methods and systems for operating an ELIT are provided herein. In accordance with various aspects of the present teachings, and ELIT is provided that can enable simultaneous trapping of two different groups of ions as each group oscillates along a different path length within the ELIT.
Claims20
An electrostatic linear ion trap (ELIT), comprising:
- a first set of electrode plates having holes in the center and aligned along a central axis;
- a second set of electrode plates having holes in the center and aligned along the central axis;
- one or more voltage sources;
- and
- a controller, operably coupled to the one or more voltage sources, configured to:
- apply voltages from the one or more voltage sources to a first group of plates of the first and second sets of electrode plates to cause the first group of plates to trap a first group of ions within a first path length along the central axis;
- and
- simultaneously
- apply voltages from the one or more voltage sources to a second group of plates of the first and second sets of electrode plates to cause the second group of plates to trap a second group of ions within a second path length along the central axis, wherein the second path length is longer than the first path length.

A method of operating an electrostatic ion trap (ELIT), comprising:
- applying voltages from one or more voltage sources to a first group of plates of a first set of electrode plates and a second set of electrode plates, wherein each electrode plate of the first and second sets of electrode plates have a hole in the center aligned along a central axis, wherein the application of voltages causes a first group of ions to be trapped within a first path length along the central axis defined by the first group of plates;
- and
- simultaneously applying voltages from the one or more voltage sources to a second group of plates of the first and second sets of electrode plates to cause the second group of plates to be configured to trap a second group of ions within a second path length along the central axis, wherein the second path length is longer than the first path length.
