Tormac 4 features the production, containment, and heating of plasma within a 48 cm O.D. toroidal chamber. The plasma has a predicted shield-shaped cross section, an included toroidal magnetic field component, and is contained by a two-pole cusp magnetic fluid comprised of both toroidal and poloidal components. The principal plasma heating is provided by an additional magnetic field component at 0.7 MHz. An electrolytic, analog tank facilitates the coil design and indicates that 18 kJ is sufficient to produce a uniform 6 kG on the plasma surface. An integral winding system for the poloidal and toroidal field coils minimizes coupling problems and simplifies insulation requirements. Single turn coils for preionization and heating are applied external to the poloidal-toroidal windings, and the whole device is reinforced with PVC plates and steel tie rods. Modified author abstract
