  • Patent number: 7139349
    Abstract: A spherical neutron generator is formed with a small spherical target and a spherical shell RF-driven plasma ion source surrounding the target. A deuterium (or deuterium and tritium) ion plasma is produced by RF excitation in the plasma ion source using an RF antenna. The plasma generation region is a spherical shell between an outer chamber and an inner extraction electrode. A spherical neutron generating target is at the center of the chamber and is biased negatively with respect to the extraction electrode which contains many holes. Ions passing through the holes in the extraction electrode are focused onto the target which produces neutrons by D-D or D-T reactions.

  • Publication number: 20040141578
    Abstract: A nuclear fusion reactor comprising a spherical reaction chamber with a mirrored interior surface filled with a nuclear fusible and laser active gaseous medium such as deuterium. Using rapid gaseous expansion caused by a focused pulsed laser source and/or timed oscillations from piezoelectric transducer, a harmonic spherical acoustic wave pattern centered within the reaction chamber is created. This wave pattern is created near a desired frequency and centered in the sphere. The wave pattern contains a central gaseous ball of high-density, pressure, and temperature that causes ionization and radiation to occur. This radiation causes the mirrored chamber to activate a spherical laser effect focused on the high pressure plasma at the center of the reaction chamber. This spherical laser pulse acting on high pressure high-density of the central standing wave produces ignition of the gas and fusion.

    Abstract: A host liquid, such as a liquid metal, which is "seeded" with small bubbles of an inert gas, is maintained in a sealed chamber at an ambient temperature of about 100.degree. K. above the melting point of the host liquid, and at a static pressure ranging from 1 to 100 bars. A substance (for example carbon) which is capable of being allotropically transformed from a first form thereof (for example graphite) to a second form (for example diamond), is placed in the host liquid, which is then subjected to a time-varying acoustical pressure applied, for example, by a plurality of solid acoustical horns, which cause at least certain of the bubbles of inert gas to expand and then suddenly to collapse in a cavitation zone located substantially centrally of the chamber.

  • Patent number: 4444717
    Abstract: A process to produce energy with the fusion of hydrogen and carbon in a thermonuclear fusion reaction with an extension, wherein carbon targets are bombarded with a beam of fast protons at temperatures of 457 kev. The thermonuclear fusion reaction produces two helium atoms and two neutron particles.The neutrons are captured by a blanket of lithium 7 which cools the walls and carries the heat to a turbulent heat exchanger, then to a generator and turbine complex which generates energy, giving tritium as a sub-product.The helium atoms plus alpha particles and protons are extracted to the reactor's extension where, combined with the tritium emitted in the first cycle of the thermonuclear fusion reactor, they go to generate more energy.This process becomes self-maintaining once the thermonuclear fusion reactor is put into operation.

  • Patent number: 4343223
    Abstract: A multiple stage magnetic railgun accelerator (10) for accelerating a projectile (15) by movement of a plasma arc (13) along the rails (11,12). The railgun (10) is divided into a plurality of successive rail stages (10a-n) which are sequentially energized by separate energy sources (14a-n) as the projectile (15) moves through the bore (17) of the railgun (10). Propagation of energy from an energized rail stage back towards the breech end (29) of the railgun (10) can be prevented by connection of the energy sources (14a-n) to the rails (11,12) through isolation diodes (34a-n). Propagation of energy from an energized rail stage back towards the breech end of the railgun can also be prevented by dividing the rails (11,12) into electrically isolated rail sections (11a-n, 12a-n). In such case means (55a-n) are used to extinguish the arc at the end of each energized stage and a fuse (31) or laser device (61) is used to initiate a new plasma arc in the next energized rail stage.

  • Patent number: 4333796
    Abstract: Two different cavitation fusion reactors (CFR's) are disclosed. Each comprises a chamber containing a liquid (host) metal such as lithium or an alloy thereof. Acoustical horns in the chamber walls operate to vary the ambient pressure in the liquid metal, creating therein small bubbles which are caused to grow to maximum sizes and then collapse violently in two steps. In the first stage the bubble contents remain at the temperature of the host liquid, but in the second stage the increasing speed of collapse causes an adiabatic compression of the bubble contents, and of the thin shell of liquid surrounding the bubble. Application of a positive pressure on the bubble accelerates this adiabatic stage, and causes the bubble to contract to smaller radius, thus increasing maximum temperatures and pressures reached within the bubble. At or near its minimum radius the bubble generates a very intense shock wave, creating high pressures and temperatures in the host liquid.

  • Patent number: H599
    Abstract: An apparatus and method for simulating a fusion environment on a first wall or blanket structure. A material test specimen is contained in a capsule made of a material having a low hydrogen solubility and permeability. The capsule is partially filled with a lithium solution, such that the test specimen is encapsulated by the lithium. The capsule is irradiated by a fast fission neutron source.
