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

摘要

A high performance magnetic field reversal coordination system includes a central confinement vessel, two diametrically opposed inverted field-theta-pinch forming portions connected to the vessel, and two diverter chambers connected to the forming portions. 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 pulsed power shaping system that enables static and dynamic shaping and acceleration of the FRC. The FRC system further includes a neutron atom beam injector, a pellet injector, a gettering system, an axial plasma gun, and a positive surface biasing electrode. The beam injector is suitably tilted towards the midplane of the chamber. In operation, the FRC plasma parameters, including plasma thermal energy, total particle count, radius, and trapped magnetic flux, are maintainable at or near constant value without decay during neutron beam implantation.
