Abstract
An electron-ion interaction module for use in a mass spectrometer, having a plurality of rod sets arranged relative to one another such that said rod sets share a common longitudinal axis and each of said rod sets is longitudinally separated from an adjacent rod set by a gap, each of said rod sets comprising a plurality of rods arranged around said common longitudinal axis. The module further includes at least one magnet disposed around said rod sets so as to at least partially surround one or more of said plurality of rod sets and configured to generate a static magnetic field along said longitudinal axis. The rod sets are configured to receive electrons from an electron source and ions from an ion source within an interaction volume defined by the rods. One or more RF voltage sources coupled to the plurality of rod sets applies voltages to the rods.
