Abstract (en)

Disclosed herein is an ion guide (42) for guiding an ion beam along an ion path, said ion guide having a centerline (46) corresponding to said ion path, and a plurality of electrodes extending along said centerline. The electrodes are formed by conductive electrode plates (44) which are radially arranged around said centerline (46), wherein each of said electrode plates (44) has a radially inner edge (48) that is closest to the centerline (46), and wherein an inner envelope of the radially inner edges (48) defines an ion guide volume. Said electrode plates (44) are connected or connectable with an RF voltage source for applying voltages collectively confining ions within said ion guide volume.
