Abstract:
A high performance field reversed configuration (FRC) system includes a central confinement vessel, two diametrically opposed reversed-field-theta-pinch formation sections coupled to the vessel, and two divertor chambers coupled to the formation sections. A magnetic system includes quasi-dc coils axially positioned along the FRC system components, quasi-dc mirror coils between the confinement chamber and the formation sections, and mirror plugs between the formation sections and the divertors. The formation sections include modular pulsed power formation systems enabling static and dynamic formation and acceleration of the FRCs. The FRC system further includes neutral atom beam injectors, pellet injectors, gettering systems, axial plasma guns and flux surface biasing electrodes. The beam injectors are preferably angled toward the midplane of the chamber. In operation, FRC plasma parameters including plasma thermal energy, total particle numbers, radius and trapped magnetic flux, are sustainable at or about a constant value without decay during neutral beam injection.

Claim (Index 22):
A system for generating and maintaining a field reversed configuration (FRC) plasma comprising\n a confinement chamber, first and second diametrically opposed FRC formation sections coupled to the confinement chamber, first and second divertors coupled to the first and second formation sections, first and second axial plasma guns operably coupled to the first and second divertors, the first and second formation sections and the confinement chamber, a plurality of neutral atom beam injectors coupled to the confinement chamber and oriented to inject neutral atom beams toward a mid-plane of the confinement chamber at an angle of about 15\u00b0 to 25\u00b0 less than normal to a longitudinal axis of the confinement, and a magnetic system coupled to the confinement chamber, the first and second formation sections, and the first and second divertors, the magnetic system including first and second mirror plugs position between the first and second formation sections and the first and second divertors, wherein upon formation by the system of an FRC within the confinement chamber of the system, the FRC being maintainable by the system in spaced relation to the wall of the confinement chamber and at or about a constant value without decay while neutral atom beams are injected from the plurality of neutral atom beam injectors into the FRC at an angle of about 15\u00b0 to 25\u00b0 less than normal to the longitudinal axis of the confinement chamber and towards the mid-plane of the confinement chamber.
