Abstract: A non-resonance photo-neutralizer for negative ion-based neutral beam injectors. The non-resonance photo-neutralizer utilizes a nonresonant photon accumulation, wherein the path of a photon becomes tangled and trapped in a certain space region, i.e., the photon trap.

The photons with a sufficiently small angle of deviation from the nearest common normal are confined. Depending on specific conditions, the shape of the mirror surface may be one of spherical, elliptical, cylindrical, or toroidal geometry, or a combination thereof.

The systems employ a disc shaped cloud of ions wherein the turning region for the recirculating ions are located in a circular space around the periphery of the disc-shaped ion cloud, thereby maximizing the turning space region to increase the number of ions trapped in the device compared to discrete beam devices, which in turn enables higher fusion yield compared to prior art devices.

Abstract: A fusion device produces fusion of neutral atoms and ions in an “aneutronic fusion” manner without neutrons as products utilizes strong ion-neutral coupling at high neutral densities. Ions and neutrals rotate together in a cylindrical chamber due to frequent collisions. High magnetic forces make the attainment of high rotation energy possible; the magnetic field in a medium can be set at very high values because of the absence of magnetic charges. The repeated acceleration by strong magnetic forces in the azimuthal direction makes possible very high ion velocity. Fusion takes place mainly between neutral particles. This approach can be applied to fusion with neutrons as well. Conventional fusion schemes and neutron sources can be realized using the principles described above in the generation of neutrals of high energies and densities.

Abstract: A fusion device consisting of two colliding ion beams, each produced by a high power, femtosecond regime, chirped pulsed amplification (CPA) laser acceleration device. The CPA laser creates an ionized plasma and subsequently accelerates electrons to multi-MeV energies, thus creating electric fields due to separation of electrons and ions, of sufficient magnitude to accelerate the plasma ions to energies ranging from multi-keV to multi-MeV levels. The magnetic fields created by the laser pulses, as well as the electrons and/or ions, also helps confine the ions to the region of the size of the laser beam focal spot diameter, and thus enhance the collision probability of the counter-streaming ions and provide a sizable population of fusion events. Ion beam generation by high powered, short pulse CPA lasers has been previously demonstrated in thin foil targets.

Abstract: A method and apparatus for transporting a positive ion beam to a distant target. An ion channel is created as a path to the target, and the beam injected into the channel at a mildly-relativistic beam velocity. Because the beam is mildly-relativistic, the electric field caused by its positive charge propagates well in advance of the beam, attracting free electrons in the plasma channel and pulling them into the beam along its axis of propagation. The current which is initiated by this precursor electron flow, is sustained during the duration of the beam, and is then a combination of the beam current and additional current carried by the electrons within the channel. As a result, a magnetic flux circulates annularly about the beam of a sufficient magnitude to pinch the beam.

Abstract: An ion ring accelerator employs a pulsed magnetic field to accelerate a charge neutralized ion ring. The accelerator includes a plurality of accelerator modules arranged either in a linear or a recirculating manner, each of which cause an incremental acceleration of the ion ring. As the ion ring enters one of the accelerator modules, a pulse is applied to a coil or resonant cavity in the module which increases in magnitude and synchronism with the passage of the ion ring. As a result, the ion ring is exposed to an increasing magnetic field in the module which compresses the ring, thereby adiabatically increasing its energy. As the ion ring exits the module and is no longer exposed to the increase in magnetic field, it expands, thereby releasing energy and accelerating in an axial direction. The repetition rate of the high current ion ring accelerator will be determined by the power supplies for the modules.
