FRC SYSTEMS AND METHODS FOR FORMING AND MAINTAINING A HIGH PERFORMANCE FRC

摘要

The high performance field reversed configuration system includes a central confinement vessel, two oppositely reversed field-theta-pinch forming portions connected to the vessel, and two diverter chambers connected to the forming portion. The magnetic system includes a quasi-dc coil positioned axially along the FRC system component, a quasi-dc mirror coil between the confinement chamber and the forming portion, and a mirror plug between the forming portion and the diverter. The forming portion includes a modular pulse power forming system that enables static formation and dynamic formation and acceleration of the FRC. The FRC system further includes a neutron atomic beam injector, a pellet or CT injector, a gathering system, an axial plasma gun, and a positive surface biasing electrode. The beam injector is appropriately tilted toward the middle plane of the chamber. In operation, FRC plasma parameters, including plasma thermal energy, total number of particles, radius, and trapped magnetic flux, can be maintained at a constant or nearly constant value without decay during neutron beam implantation.
