Abstract
An apparatus for generating a highly energetic plasma employs a low-energy neutral beam injected into a magnetically contained mirror plasma to produce plasma ions boosted in energy to fusion levels by a coordinated radiofrequency field.
Claims17
An apparatus for producing high-energy plasma comprising:
- a magnetic mirror containment field providing axially-extending magnetic flux lines converging at opposed first and second ends of a containment volume holding a plasma;
- a neutral beam generator directing a neutral beam of particles into the containment volume at a predetermined pitch and energy so that the particles disassociate into plasma ions within the containment volume, and
- a radiofrequency generator producing an electrical field to accelerate the plasma ions to an energy sufficient for fusion of the plasma ions.
A fusion apparatus comprising:
- a reaction volume holding a fusible material within a first axially-extending magnetic containment field;
- a first and second plasma plug flanking the reaction volume along the axis;
- each plasma plug including:
- (a) a magnetic mirror containment field providing axially-extending magnetic flux lines converging at opposed first and second ends of a containment volume holding a plasma;
- (b) a neutral beam generator directing a neutral beam of particles into the containment volume at a predetermined pitch and energy so that the particles disassociate into plasma ions within the containment volume;
- and
- (c) a radiofrequency generator producing an electrical field to accelerate the plasma ions to an energy above that of the particles entering the containment volume;
- whereby plasma ions escaping from the first and second plasma plug produce a fusion reaction in the reaction volume.
