1. An ion manipulation device, comprising:
an ion manipulation structure comprising one or more pairs of opposing curved surfaces sharing a common longitudinal axis and radially spaced from one another by a radial gap along a radius of the ion manipulation structure, each pair of opposing curved surfaces comprising a first electrode arrangement and a second electrode arrangement opposed to the first electrode arrangement, wherein the first and second electrode arrangements define an ion pathway through the radial gap and are configured to direct ions along the ion pathway and circumferentially through the radial gap;
wherein the first and second electrode arrangements include respective sets of segmented electrodes arranged along the direction of the ion pathway and configured to receive time-varying voltages that direct the ions along the ion pathway.
