An apparatus includes a first pair of opposing electrode arrangements that confine ions between them in a portion of a confinement volume inwardly laterally in a first confinement direction with respect to a longitudinal ion propagation direction, each opposing electrode arrangement including an arrangement of RF electrodes situated to receive an unbiased RF voltage having an alternate phase between adjacent RF electrodes of the arrangement of RF electrodes so as to provide the confining of ions between the first pair of opposing electrode arrangements, and a second pair of opposing electrode arrangements that confine the ions between the second pair in the confinement volume inwardly laterally in a second confinement direction that complements the first confinement direction, each opposing electrode arrangement of the second pair including an arrangement of RF electrodes that receive an unbiased RF voltage having an alternate phase between adjacent RF electrodes.
