Abstract
A fusion device provides for the reaction of atomic nuclei, preferably deuterons and tritons, to generate reaction products with kinetic energies convertible to useful energy. First and second sources of first and second positive ions provide such ions at temperatures in a range where the ions have a substantially optimum cross section for mutual reaction. The respective ions are accelerated to substantially the same mean velocity and formed into respective beams. The beams are neutralized and directed into a portion of a reaction chamber substantially orthogonally of a substantially constant unidirectional magnetic field as first and second polarized beams of respective first and second positive hot ions. The polarization of the first and second polarized beams is drained, preferably by a plasma created in the portion of the reaction chamber, to separate the neutralizing electrons from the respective first and second positive hot ions. The strength of the magnetic field and the velocities of the separated first and second positive hot ions provide centripetal force on the respective first and second positive hot ions to confine the ions to respective orbits within the portion of the reaction chamber. The directions and relative velocities of the separated first and second positive hot ions make the respective orbits for the first and second positive hot ions substantially coextensive. The ions orbit in the same direction at substantially the same mean velocity. The first and second ions are preferably deuterons and tritons, respectively, having a temperature of about 50 keV. The deuterons are preferably accelerated to about 400 keV, and the tritons are accelerated to about 600 keV. The ions have substantially drifted Maxwell distributions of energy.
