Abstract: A chamber cross-sectional multi-stage plasma arrangement characterized by escalating charge movement towards chamber center axis through one or more escalation stages contributing to the heating of the plasma, the centering of the plasma on the chamber axis, and creating rotation of the plasma therein. Rotation of the plasma around its axis induces a self-generated magnetic field, which in turn increases plasma stability and confinement. Some of the said stages of the multi-stage arrangement may be created by physical elements and components while others may be induced or generated by externally applying magnetic and/or electric fields or their combinations and/or by injection of electrons, ions or other plasma.

Abstract: A weakly ionized plasma of ions and neutrals is generated from a first reactant in a confinement region. Orthogonal electric and magnetic fields induce azimuthal rotation of the ions around a longitudinal axis of the confinement region, the azimuthal rotation of the ions imparting azimuthal rotation to the neutrals of the first reactant, and promoting repeated collisions between one or both of the ions and the neutrals with a second reactant. The repeated collisions produce an interaction between the neutrals and the second reactant that produces a product having a nuclear mass that is different from a nuclear mass of any of the nuclei of the neutrals and the second reactant.

Abstract: A method of containing plasma and forming a Field Reversed Configuration (FRC) magnetic topology. A magnetic guide field is created within a cylindrical chamber. The guide field has field lines axially extending within the chamber parallel to the longitudinal axis. A plasma of charged electron and ion particles is injected into the chamber. The plasma is caused to rotate, which forms a magnetic poloidal self-field surrounding the rotating plasma due to the current carried by the rotating plasma. The rotational energy of the plasma is increased to increase the magnitude of the self-field to a level that overcomes the magnetic guide field axially extending within the chamber, which causes the formation of a magnetic field within the chamber with FRC topology.

Abstract: A novel arrangement that combines in a single compact embodiment a plasma flow switch source of ultrahigh speed plasma and an electromagnetically-imploded cylindrical shell. The shell, known as a liner, forms the wall of a cavity that receives and stagnates the plasma flow. The plasma and the liner are connected electrically in series so that a single multi-megampere current serves both elements and operates from the same power source and switch. The operation is timed so that the plasma is injected into the cavity once the liner has attained sufficient implosion speed. The liner then continues to implode, reducing the cavity volume and compressing the plasma further to very high temperatures and densities, thereby creating a compact, intense pulsed neutron source generated by thermonuclear reactions in the compressed plasma. Such a neutron source has application for neutralizing bio/chemical warfare agents, radiography, and material processing.

Abstract: An inductive transformer in the form of a solenoidal coils aligned along the major axis of a flux core induces poloidal flux along the flux core's axis. The current in the solenoidal coil is then reversed resulting in a poloidal flux swing and the conversion of a portion of the poloidal flux to a toroidal flux in generating a spheromak plasma wherein equilibrium approaches a force-free, minimum Taylor state during plasma formation, independent of the initial conditions or details of the formation. The spheromak plasma is sustained with the Taylor state maintained by oscillating the currents in the poloidal and toroidal field coils within the plasma-forming flux core. The poloidal flux transformer may be used either as an amplifier stage in a moving plasma reactor scenario for initial production of a spheromak plasma or as a method for sustaining a stationary plasma and further heating it.

A second accelerating system may introduce a second beam of different velocity creating an instability and turbulent mixing of the two beams, which are favorable for a fusion reaction.

Abstract: This is one of a series of nuclear fusion (vs. fission) inventions by this physicist-inventor. 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. Boron hydride comes in gas, liquid or solid form, stable or unstable. The invention at hand proposes to accelerate macromolecular ions of boron hydride (such as B.sub.2 H.sub.

Abstract: Apparatus and method for maintaining steady state compact toroidal plasmas. A compact toroidal plasma is formed by a magnetized coaxial plasma gun and held in close proximity to the gun electrodes by applied magnetic fields or magnetic fields produced by image currents in conducting walls. 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.

Abstract: An intense, space-charge-neutralized, pulsed ion beam is used to heat a metically-confined plasma, such as a tokamak plasma, by injecting the ion beam into the plasma along a trajectory that is generally tangential to the confining magnetic field. The ion beam inductively generates a plasma return current so that no net current is produced. As the ion beam drifts in the plasma, the confining magnetic field is transformed into one which can trap the ion beam at the center of the plasma. Once the ion beam is trapped, the plasma return current is cancelled by transformer action to produce a net current which is carried by the ion beam alone. The beam transfers its energy to the plasma by classical collisions with the electrons and ions of the plasma. Heating of the plasma can be sufficient to produce a breakeven condition or ignition.

Abstract: A nuclear fusion process for igniting a nuclear fusion pellet in a manner similar to that proposed for laser beams uses, an array of pulsed high energy combined particle beams focused to bombard the pellet for isentropically compressing it to a Fermi-degenerate state by thermal blow-off and balanced beam momentum transfer. Each combined particle beam is arranged to produce electric charge neutrality in a volume around the target so that space charge induced expansion is avoided. Each high energy combined beam is produced by merging in neutralizing proportion a convergently focused stream of positive particles and at least one convergently focused stream of negative particles to form an electrically neutralized combined beam having a deBroglie wavelength focal pattern at the region of pellet collision. The momentum and fusible mass of the particle beams reduce the ablation loss and result in a larger fraction of the pellet being available for fusion reaction.

Abstract: An Atomic Fusion Device wherein a laser beam is focused to the center of a spherical reaction chamber having a mirrored inner surface. The spherical reaction chamber is evacuated and surrounded by a concentric lithium jacket which is surrounded by a concentric cryogenic jacket in which is immersed a multiaxis Ioffe bar system. A mixture of deuterium and tritium plasma is continuously introduced into the reaction chamber at a metered rate through the preheat units and compressed at the center of the chamber by the electromagnetic field created by the superconductive Ioffe bar system. This mixture is ignited by the laser beam to create a steady-state, self-sustaining lithium blanket. Power is controlled by controlling the plasma input rate and energy is coupled out of the device by electromagnetic coupling or by recirculating the lithium through a heat exchanger.
