Systems and methods for improved sustainment of a high performance frc plasma at elevated energies utilizing neutral beam injectors with tunable beam energies

A system for generating and maintaining a magnetic field with a field reversed configuration (FRC) comprising

• a confinement chamber,
• first and second diametrically opposed FRC formation sections coupled to the first and second diametrically opposed inner divertors,
• first and second divertors coupled to the first and second formation sections,
• one or more of a plurality of plasma guns, one or more biasing electrodes and first and second mirror plugs, wherein the plurality of plasma guns includes first and second axial plasma guns operably coupled to the first and second divertors, the first and second formation sections and the confinement chamber, wherein the one or more biasing electrodes being positioned within one or more of the confinement chamber, the first and second formation sections, and the first and second outer divertors, and wherein the first and second mirror plugs being position between the first and second formation sections and the first and second divertors,
• a gettering system coupled to the confinement chamber and the first and second divertors,
• a plurality of neutral atom beam injectors coupled to the confinement chamber and angled toward a mid-plane of the confinement chamber, wherein one or more of the plurality of neutral atom beam injectors are tunable between a first beam energy and a second beam energy, wherein the second beam energy differ from the first beam energy, and
• a magnetic system comprising a plurality of quasi-dc coils positioned around the confinement chamber, the first and second formation sections, and the first and second divertors, and first and second set of quasi-dc mirror coils positioned between the first and second formation sections and the first and second divertors.
