Abstract
In various embodiments, provided are ion optics systems comprising an even number of ion mirrors arranged in pairs such that a trajectory of an ion exiting the ion optics system can be provided that intersects a surface substantially parallel to an image focal surface of the ion optics system at a position that is substantially independent of the kinetic energy the ion had on entering the ion optics system. In various embodiments, provided are ion optics systems comprising an even number of ion mirrors arranged in pairs where the first member and second member of each pair are disposed on opposite sides of a first plane such that the first member of the pair has a position that is substantially mirror-symmetric about the first plane relative to the position of the second member of the pair.
Claims8
An ion optics system comprising:
- a first ion mirror;
- a second ion mirror, the first ion mirror and the second ion mirror disposed on opposite sides of a first plane such that the first ion mirror has a position that is substantially mirror-symmetric about the first plane relative to the position of the second ion mirror;
- a third ion mirror;
- and
- a fourth ion mirror, the third ion mirror and the fourth ion mirror disposed on opposite sides of the first plane such that the third ion mirror has a position that is substantially mirror-symmetric about the first plane relative to the position of the fourth ion mirror;
- wherein the first ion mirror, the second ion mirror, the third ion mirror and the fourth ion mirror are arranged such that a trajectory of an ion exiting the ion optics system can be provided that intersects a surface substantially parallel to a focal surface of the ion optics system at a position that is substantially independent of ion kinetic energy.
An ion optics system comprising:
- two or more pairs of ion mirrors, each pair of ion mirrors comprising a first member and a second member;
- the members of each pair of ion mirrors disposed on opposite sides of a first plane such that the first member of a pair of ion mirrors has a position that is substantially mirror-symmetric about the first plane relative to the position of the second member of the pair,
- the two or more pairs of ion mirrors arranged such that a trajectory of an ion exiting the ion optics system can be provided that intersects a surface substantially parallel to a focal surface at a position that is substantially independent of the kinetic energy of the ion on entering the ion optics system.
