Cellular, electron cooled storage ring system and method for fusion power generation

A cellular electron cooled storage ring system and method for achieving particle-fusion based energy, including a vacuum chamber to allow electron beam and ion beam merging and separation, cathodes to generate the electron beams, collectors to collect the electron beams, and magnetic field generation devices to guide the electrons and ions on their desired trajectories as well as contain neutralizing particles. By overlapping the electron and ion beams, thermal energy is transferred from the ion beams to the electron beams, which allows the invention to overcome particle losses due to resonances, scattering and heating of the ion beams. Advantageously, ions are accelerated to an energy that is near optimum for fusion reactions to occur, and uses electron energies that maintain this advantageous situation. Advantageously, the recirculation of ions that do not fuse or scatter at too large of an angle is allowed, giving such ions additional chances to participate in a desired fusion reaction. Advantageously, the invention allows for a continual addition of new ions to be added to the circulating ions already in the system. This combination of advantages results in a significant improvement in the predicted output power to input power ratio over previous particle fusion technologies. The invention will also enable improved yields of fast neutrons for materials testing.
