Abstract

See full text

An ion trap (100) includes a first electrode pair (110) and a second electrode pair (130), each including a first conductive member (112) and a second conductive member (120) and facing each other so that the first conductive member (112) of the first electrode pair (110) is on a common plane with the second conductive member (120) of the second electrode pair (130) and so that the second conductive member (120) of the first electrode pair (110) is on a common plane with the first conductive member (112) of the second electrode pair (130), a gap (132) therebetween. A signal generator (210) generates a periodic signal (212) applied to the first conductive members (112). A phase shifter (216) generates a second periodic signal (218) that is 180 out of phase therewith applied to the second conductive members (120). Ions are trapped by a resulting electric field.
