The present invention is directed to a gas line electron beam exciter, gas line electron beam excitation system and method for exciting a gas using an electron beam exciter. The electron beam exciter generally comprises a variable density electron source for generating a cloud of electrons in an electron chamber and a variable energy electron extractor for accelerating electrons from the electron chamber as an electron beam and into an effluent stream for fluorescing species in the effluent. The electron density of the electron beam is variably controlled by adjusting the excitation power applied to the variable density electron source. The electrons in the electron chamber reside at a reference electrical potential of the chamber, typically near ground electrical potential. The electron energy of the electron beam is variably controlled by adjusting an electrical potential across the variable energy electron extractor, which energizes the electrons through an extraction hole of the chamber and toward the extractor. The greater the difference in the electrical potential between the electron extractor and the electron source, the higher the energy imparted to the electrons in the electron beam. The excitation power applied to the electron source can be adjusted independently from the electron energy of the electron beam, thereby altering the electron density of the electron beam without changing the energy level of the electrons of the electron beam.

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.
