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. The traveling field may be generated by a group of electromagnets, with or without cores, spaced along the path and excited in staggered phase relationship; by an angular offsetting of the polar axes of adjoining electromagnets, the quasi-cycloidal trajectories may…
