Abstract
An ion guide generates a radio frequency (RF) field to radially confine ions to an ion beam along a guide axis as the ions are transmitted through the ion guide. The effective potential of the RF field has potential wells distributed along the guide axis. The RF field is constructed such that the potential wells move in an axial direction toward an exit end of the ion guide.
