Apparatus include a plurality of electrode arrangements spaced apart from each other opposite an ion propagation axis and defining an ion transfer channel that extends along the ion propagation axis that tapers between an input end that is situated to receive ions and an output end that is situated to couple the received ions to an input end of an ion guide. Methods include positioning a plurality of electrode arrangements at oblique angles opposite an ion propagation axis so as to form a ion transfer channel that tapers between an input end and an output end, and coupling the output end of the ion transfer channel to an input end of an ion optical element so as to direct ions in the ion transfer channel into the ion optical element. Related systems are also disclosed.
