  • Publication number: 20080112528
    Abstract: In a chemonuclear fusion in which hydrogen ions of nuclear stopping power energy of a few keV per nucleon, that is, deuteron or proton beam are implanted into a liquid target of molten metal lithium, the reaction rate is increased by about 1011 times by thermodynamic force in the liquid. For putting chemical nuclear fusion to practical use, there is needed to increase the reaction rate by further increasing the thermodynamic force.

  • Patent number: 7002148
    Abstract: A system and apparatus for controlled fusion in a field reversed configuration (FRC) magnetic topology and conversion of fusion product energies directly to electric power. Preferably, plasma ions are magnetically confined in the FRC while plasma electrons are electrostatically confined in a deep energy well, created by tuning an externally applied magnetic field. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions they are fused together by the nuclear force, thus forming fusion products that emerge in the form of an annular beam. Energy is removed from the fusion product ions as they spiral past electrodes of an inverse cyclotron converter. Advantageously, the fusion fuel plasmas that can be used with the present confinement and energy conversion system include advanced (aneutronic) fuels.

  • Publication number: 20040213368
    Abstract: Ionized boron and protons are used a nuclear reactants in a field-reversed configuration system, and fuse to yield three alpha particles with kinetic energy convertible to useful energy. The boron and proton beams are injected into the reaction chamber in such a manner as to have a relative energy of 0.65 MeV, corresponding to a resonance maximum in the reaction cross-section. The boron beam has energy of 0.412 MeV and the proton beam has energy of 1 MeV. Furthermore, in the device of the invention, the beams tend to circulate in the same direction, thereby avoiding rapid change in the mean velocities of the beams due to ion-ion scattering. The ions remain confined for relatively long periods, enhancing fusion collisions. Both ion beams should not have temperatures greater than 100 keV, because this will detract from the resonance in cross-section.

  • Patent number: 6680480
    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.

Being an educated physicist myself from the University of California at Riverside and with all due respect to scientists, as Einstein once said, “Keep it simple stupid,” is a guiding phenomenon in all of physics.

  • Patent number: 5825836
    Abstract: The subject invention is a nuclear fusion reactor. It operates by colliding particle beams from at least four different directions. The beams collide in a matrix that guides the particles to the reaction's center by their mutual electrostatic repulsion. In the preferred embodiment the reactor comprises primarily four high energy particle accelerators (11a, 11b, 11c, and 11d). At the reactor's center, the accelerators' four beams intersect at angles of approximately 109.471220634491 degrees. The exact measure of the preferred angle is given by the measure of the obtuse interior angle of an isosceles triangle that has two sides measuring the square root of three units and a base measuring twice the square root of two units. Accelerated to fusion producing velocities, the four particle beams intersect in a high-vacuum reaction chamber (12). The resulting collision matrix funnels the accelerated particles into the center of the reaction zone causing some of the fuel particles to fuse rather than to scatter.

  • Patent number: 5339336
    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.

  • Patent number: 5162094
    Abstract: An approach (10) is provided as a way of obtaining useful power from a fusion reaction utilizing light weight isotopes of hydrogen and helium. A potential well is created between two accelerating electrodes (26) that, in a vacuum, allows ions from sources (24) to be captured by the potential well. An axial magnetic field as created by solenoid (20) causes the captured ions to pass through an ion focusing region (22) and thus allowing fusion reactions to take place within the region. The magnetic field also confines the trajectory of the fusion products (18) to a series of helixes preventing them from reaching the solenoid walls, but instead forces them to exit the two ends of the solenoid. Useful power is obtained by allowing two heat exchangers to intercept the fusion ions and thereby allowing a coolant liquid to be heated as would be required to operate a steam turbogenerator.

    Abstract: This invention relates to adaptation of intersecting storage rings, of the same type used in high energy nuclear physics research, for power generation. The device is optimized for lower-energy beam paricles and higher beam current, adapted with a reaction chamber at the intersection of the rings to collect released fusion energy for conversion to electricity, and equipped with means to recapture scattered accelerated particles and reintegrate them into the focused beams for recirculation through the reaction chamber. The preferred beam particles, deuterium and tritium, are accelerated and injected into and focused by the storage rings, to collide nearly head on in the reaction chamber. Non-colliding, accelerated beam particles are conserved by recovery, correction and recirculation, requiring relatively small amounts of input energy to maintain acceleration and focus of the beams, and thus remain energized for another collision attempt.

    Abstract: The present invention is a nuclear fusion reactor serving to contain a totally organized tritium-deuterium plasma by guiding the self-bombarding particles in a resonating path of a particular wavelength and frequency, similar to a radio wave. Under these conditions the electrons tend to remain cooler, which reduces plasma radiation energy losses. Energy may be added to the plasma by axially distributed oscillators of the proper frequency, raising the plasma to ignition temperature and densities. Finally the ignited plasma directs its high energy neutrons into strategically located lithium blankets and the ionic energy levels are controlled by causing the plasma to generate an alternating electric current. Various types of alternate fusion reactions are briefly considered.

This invention is designed to burn the cleanest of all known fusion fuels: boron hydride (B-H, or p-.sup.11 B). Boron hydride has no free neutrons on either side of its reaction equation: p+.sup.11 B=3.alpha.+W. If this fuel can be made to fuse as planned the many problems associated with neutron-based fuels, deuterium-tritium (D-T) in particular, can be obviated. D-T gives off 80% of its energy in the form of neutrons. These make the apparatus radioactive; and the neutrons may be used to breed weapons grade fission material. Whereas, p-.sup.11 B cannot be used to make fission bomb material; its product particles are entirely safe inert helium particles. B-H fuel is abundant, available and inexpensive.

Voltage supply means maintains a constant potential across the electrodes producing an increasing magnetic helicity which drives the plasma away from a minimum energy state. The plasma globally relaxes to a new minimum energy state, conserving helicity according to Taylor's relaxation hypothesis, and injecting net helicity into the core of the compact toroidal plasma. Controlling the voltage so as to inject net helicity at a predetermined rate based on dissipative processes maintains or increases the compact toroidal plasma in a time averaged steady state mode.
