摘要：

Mass spectrometry cells include one or more interleaved magnetostatic and electrostatic lenses. In some examples, the electrostatic lenses are based on electrical potentials applied to magnetostatic lens pole pieces. In other alternatives, the electrostatic lenses can include conductive apertures. Applied voltages can be selected to trap or transport charged particles, and photon sources, gas sources, ion sources, and electron sources can be provided for various dissociation processes.
