Abstract
A divertor for system supporting plasma for fusion employs permanent magnets providing far weaker magnetic field strength than conventionally used in cryogenic magnetic systems through an ability to place the permanent magnets in close proximity to the plasma containment volume.
Claims16
An apparatus for producing plasma having an energy that allows for nuclear fusion, comprising:
- a containment volume within a vessel;
- an extraction volume outside of the containment volume;
- a containment field magnet structure providing containment magnetic flux lines, wherein the containment magnetic flux lines are configured to provide cyclonic retention of plasma ions at nuclear fusion energies in the containment volume;
- and
- a divertor magnet structure of permanent magnets located adjacent to the containment volume,
- wherein the divertor magnet structure is positioned to create an X point of zero magnetic field,
- wherein the X point allows plasma ions at a periphery of the containment volume to escape into the extraction volume.
