Abstract: Pulses of ionized gas mixtures are generated periodically, to be entrained and accelerated inside a vessel in a predetermined direction by magnetic waves traveling transverse to the plasma motion. Phase coherence between the pulse train and the magnetic waves is maintained. The forces exerted by the magnetic waves cause the ion mixture of each pulse packet to be sorted into several separate packets in some of which the original concentration of a specific ion has been greatly increased or decreased. The waves then drive each packet into a separate branch of the vessel for recovery. The distance between these branches depends on the timing of the mixed pulse relative to the crest of the magnetic waves, on ion mass-to-charge differences, and on the intensity of the magnetic field. The separation efficiency may be enhanced by reducing the intensity of the magnetic field, by raising its frequency, and by shortening the mixed plasma packets while increasing their density.

Abstract: Charged particles are entrained on a straight or curved path by a traveling magnetic field moving along that path with its magnetic flux vector transverse thereto. The general direction of entrainment is the same for particles of either polarity. The initial relative velocity between the traveling field and the particle drives the latter into motions along a quasi-cycloidal trajectory in the direction of field travel at an average particle speed nearly equal to the field velocity. Streams of charged particles may be accelerated into streams separated from any material objects such as vessel walls, magnetic structures, electrodes, etc. This confinement is achieved predominantly by the balanced interaction of the forces exerted on the particles by the traveling magnetic field and their inertial forces. Auxiliary confining fields may be applied for redirecting to the main stream any particles scattered by secondary effects.

Abstract: Charged particles are entrained in a predetermined direction, independent of their polarity, in a circular orbit by a magnetic field rotating at high speed about an axis in a closed cylindrical or toroidal vessel. The field may be generated by a cylindrical laser structure, whose beam is polygonally reflected from the walls of an excited cavity centered on the axis, or by high-frequency energization of a set of electromagnets perpendicular to the axis. In the latter case, a separate magnetostatic axial field limits the orbital radius of the particles. These rotating and stationary magnetic fields may be generated centrally or by individual magnets peripherally spaced along its circular orbit. Chemical or nuclear reactions can be induced by collisions between the orbiting particles and an injected reactant, or by diverting high-speed particles from one doughnut into the path of counterrotating particles in an adjoining doughnut.
