Abstract
Particles with different charge-to-mass ratios can be separated in a phase-sensitive process with application of a simple alternating longitudinal electric field in the absence of other electric or magnetic fields. The method suggests that a given particle can either be isolated or eliminated from a beam of several charged particles, in contrast to the conventional mass spectrometry where a particular particle is isolated. The method, based on the principles underlying phase stability in particle accelerators, could be applied to mass spectrometry or selective ion sources for plasma generation, ion traps, sputtering, or other applications. It would be especially useful in instances where the incoming ions are timed in synchrony with the proper phase of the applied voltage.
