摘要： An electron cooling system and method for increasing the phase space intensity and overall intensity of ion beams in multiple overlap regions, including a vacuum chamber to allow a single electron beam to be merged and separated with multiple ion beams, an electron supply device including a cathode to generate the electron beam, an electron collector device including a collection plate to collect the electron beam, multiple magnetic field generation devices to guide the electrons on their desired trajectories, and multiple electrodes to set the velocity of the electron beam independently in each overlap region. By overlapping the electron and ion beams, thermal energy is transferred from the ion beams to the electron beam, which allows an increase in the phase space density and overall density of the ion beams. Advantageously, the electron cooling system uses multiple magnetic field generation devices to guide the electrons into and out of multiple, separate, ion beam overlap regions, allowing the single electron beam to cool an ion beam in more than one overlap region. Advantageously, the electron cooling system uses electrodes to control the mean electron beam velocity in each overlap region, allowing for mitigation of electron beam emittance growth caused by scattering that occurs exterior to the overlap regions. Advantageously, the electrodes used to control the mean electron beam velocity in each overlap region allow for a single electron beam to achieve different velocities to match different desired ion beam velocities in the multiple overlap regions.

摘要： A storage ring system and method for high-yield nuclear production of neutrons, isotopes and photons, include a particle supply for generating a beam of projectile or reaction particles, a closed storage ring for containing and recycling the projectile particles, an electron cooling system for stabilizing the projectile particles, and a target for initiating nuclear reactions with the projectile particles so as to generate the desired end-products, with improved efficiency and safety. The invention also provides a plurality of dipoles and/or trim magnets selectively situated around the ring to guide the projectile particles as they circulate within the system. Substantially trapped in the closed storage ring, the particle beam is recirculated inside the storage ring for repeated exposure to the target, until the particles either favorably react with the target or are lost through scattering. As new particles are injected into the storage ring, they merge with previously injected particles circulating the ring, thereby allowing a relatively high intensity beam to develop, even though the input current used to populate the system remains relatively low throughout the operation of the system. Advantageously, the present invention maintains the particle beam within optimal reaction parameters by providing the electron cooling system to stabilize the particle beam.

摘要： A particle beam, segmented electron gun, segmented electron beam and electron collector system and method to achieve low power loss, segmented current control, and segmented energy control in electron beams, including a vacuum chamber to provide a region substantially free of background gas and allow for electron transport, an electron supply device including a segmented cathode to generate the segmented electron beam, an electrode with a grid conducting structure located in front of the segmented cathode and biased with respect to the segmented cathode in order to accelerate electrons away from the segmented cathode and control the current and energy of each electron beam segment, magnetic field production devices such as solenoidal and torroidal wire windings and permanent magnet material to produce magnetic fields to guide the segmented electron beam and to contain neutralizing-background-ions and an electron collector device including electrodes with a grid conducting structure and outer conducting shell structure to contain neutralizing-background-ions within one or more volume regions and one or more collection plates. The collection plates may or may not be water cooled. The segmented cathode is comprised of electron emitting segments separated by non-emitting-regions. By biasing each segment of the segmented cathode appropriately, and by heating each segment of the segmented cathode appropriately, each section of the electron beam can have its current and energy independently controlled. By biasing each segment of the collection system appropriately, efficient recovery of the electron beam can be obtained. Use of the system and method can involve overlapping the segmented electron beam on a particle beam in an overlap region, wherein thermal energy is transferred from the particle beams to the electron beam, which allows an increase in the phase space density and overall density of the particle beams.

摘要： A low energy electron cooling system and method for increasing the phase space intensity and overall intensity of low energy ion beams, including a vacuum chamber to allow electron beam and ion beam merging and separation, a cathode to generate the electron beam, a collector to collect the electron beam, magnetic field generation devices to guide the electrons on their desired trajectories, and electrodes to accelerate and decelerate the electron beam. By overlapping the electron and ion beams, thermal energy is transferred from the ion beam to the electron beam, which allows an increase in the phase space density and overall density of the ion beams. Advantageously, the low energy electron cooling system uses electrodes to set up electrostatic potentials that trap non-beam neutralizing-background-ions longitudinally within the electron cooling region and solenoidal fields that trap the non-beam neutralizing-background-ions radially within the electron cooling region. The trapped non-beam neutralizing-background-ions allow electron cooling currents that are vastly larger than the space charge limit of previous electron cooling devices, which leads to vastly improved functioning of the electron cooling device over previous electron cooling devices.

摘要： 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.
