An electrostatic containment fusion generator is comprised of a generally spherical capacitor having an outer plate at ground and a negatively charged inner plate. A reaction chamber, comprised of two pairs of spaced apart permanent magnets, is disposed within the inner plate. An ion source means provides a deuteron beam to enter into a figure-8 orbit between the two pairs of magnets. A Faraday cage exists between the two pairs which neutralizes space charge in the center region of the beam. An arced cut portion on each magnet assists in the beam's entry into the Faraday cage, while a path correction means corrects the effects of the inverse field created by the cut portion. Dual beam establishment means are also provided.
