Abstract

It is shown that if the phase difference between oscillating electric and magnetic field is judiciously chosen, particles are accelerated along a line that is perpendicular to those fields. Moreover, the direction of acceleration depends on the particle mass, so that species of different mass are accelerated in opposite directions. Two configurations are addressed. One configuration is of a linearly-polarized electric and magnetic fields. In a second configuration, a steady axial magnetic field is added to circularly-polarized oscillating fields. For an appropriate phase difference, charged particles, the cyclotron frequencies of which lie on the two opposite sides of the cyclotron resonance, are accelerated in opposite directions. Ion collisions with neutrals cause the ion acceleration to result in a drift velocity of the ions. The direction of the drift also depends on mass. The effects of collisions, initial ion velocity, and fields nonuniformity are also discussed. Separation of particles of different mass is a crucial process in a variety of societal applications.
