Dual Tokamak with Alternating Current Inductive Plasma Formation and Sustainment

Two vertically separated but connected tokamak plasma regions, termed respectively (1) the plasma formation region and (2) the fusion reaction region, share a common torroidal vacuum vessel and a common toroidal field coil system. Poloidal field coils and solenoidal coils adjacent to the plasma formation region are driven by pulsed ac electrical current to inductively create a sequence of tokamak plasma rings, each of which is ejected through the connecting duct to the fusion reaction region where it merges with a larger tokamak plasma. The process delivers volt-second flux and additional fuel to sustain continual operation of larger plasma.
