Section: abstract

Particles including fusible nuclei and electrons are contained in a fusion reaction vessel having a conductive length. The particles individually have a mass and a velocity, and are resonated by a weak magnetic field applied to the vessel at a magnetic flux density set according to a relation equating the gravitational energy of the particles with the electromagnetic energy of the applied magnetic field. The magnetic field can be applied in addition to much stronger confinement and heating magnetic fields. The flux density B of the applied field is calculated according to the equation mc.sup.2 =Bvl coulomb, where m=the mass of a particle, c=the velocity of light, v=the mean orbital velocity of the earth about the sun, and l=the plasma circumference. At least two distinct particle masses are contained in the plasma, and distinct magnetic fields can be applied to the plasma at flux densities calculated according to said equation mc.sup.2 =Bvl coulomb for at least said two distinct masses. The field is applied using electromagnet coils substantially encompassing the plasma body, in particular by poloidal coils encompassing the toroidal confinement vessel of a Tokamak type reactor.
