Abstract
A self-aligned ion guide assembly comprises a plurality of 2N rods radially contained by at least one insulating collar having two grooves axially displaced on the outer periphery of the collar. A wire in each groove electrically contacts and mechanically bonds to alternate rods through respective radially directed holes. Alternatively, the collar is cast about the assembly of rods and wires.
