Abstract

Ionized boron and protons are used a nuclear reactants in a field-reversed configuration system, and fuse to yield three alpha particles with kinetic energy convertible to useful energy. The boron and proton beams are injected into the reaction chamber in such a manner as to have a relative energy of 0.65 MeV, corresponding to a resonance maximum in the reaction cross-section. The boron beam has energy of 0.412 MeV and the proton beam has energy of 1 MeV. Furthermore, in the device of the invention, the beams tend to circulate in the same direction, thereby avoiding rapid change in the mean velocities of the beams due to ion-ion scattering. The ions remain confined for relatively long periods, enhancing fusion collisions. Both ion beams should not have temperatures greater than 100 keV, because this will detract from the resonance in cross-section.

Claims

9. A method for causing atomic nuclei in a colliding beam field-reversed configuration reactor having a field-reversed configuration of magnetic fields to react to generate reaction products, the method comprising:

(a) injecting repetitive pulses of beams of boron ions at a first predetermined mean velocity and a predetermined temperature into the field-reversed configuration of magnetic fields in the reactor; and

(b) injecting repetitive pulses of beams of protons at a second predetermined mean velocity and said predetermined temperature into the field-reversed configuration of magnetic fields in the reactor;

10. The method as recited in claim 9, wherein the steps of injecting repetitive pulses of beams of protons and boron ions include injecting said beams of protons and boron ions in a direction perpendicular to field lines of the field reversed configuration of magnetic fields.

11. The method as recited in claim 9, further comprising the steps of neutralizing said beams of protons and boron ions with electrons prior to injecting said beams of protons and boron ions into the field reversed configuration of magnetic fields, and confining said beams of protons and boron ions in orbits within the reactor.
