Abstract:
A fusion reactor includes an improved ability to modulate a plasma for specific purposes. The reactor operates on the ability to change at least four separate variables in each of a plurality of lenses that are independent of the other lenses. This allows for the generation of Alfvén waves and modulation of the internal plasma dynamics, actively leading to higher states of efficiency. By combining modulation of a plasma in the form of an ion beam with a solid state metal target, an efficient fast neutron source can be produced. This can lead to industrial applications such as energy generation, nuclear clean-up, the production of rare earth metals out of semi-rare ones, and helium production.

A macroscopic-matter hypervelocity accelerator, includes projection means (1) for suspending the projectile (7) within an evacuated chamber, an electromagnetic radiation source (12q3) which can emit non-penetrating radiation towards the projectile thereby accelerating it to hypervelocity, a target (25) that will suddenly decelerate the projectile remnant upon impact subsequently transforming its kinetic energy into nuclear fusion fuel internal energy contained within the projectile or the target which then results in thermonuclear fusion at the impact site, an inner and outer neutron blanket (27, 29) capable of transmuting elements and absorbing lower and higher-energy neutrons thereby heating the blankets which are thermally isolated (30) to maximise thermal power density for conversion to electricity, an inductor (31) capable of transforming the kinetic energy of escaping nuclei directly into electrical energy, and shielding means (33) such that escaping neutrons are safely absorbed.

Abstract:
Générateur de puissance électrique constitué par une chambre (1) contenant un mélange deuterium-hydrogène, dans laquelle l'énergie d'un puissant laser à impulsions est focalisée après avoir été transformée en mode quadripolaire tournant transerve électrique, en traversant un 'déphaseur azimutal' (8) dans lequel les déphasages sont causés par un dopage du matériau constituant les lames à faces parallèles. Ce dopage fait varier l'indice optique d'une quantité liée à la longueur d'onde du laser et à l'épaisseur de la lame. Cette énergie provoque la formation d'un plasma à partir duquel, dans une zone voisine du plan focal, des 'aiguilles' sont lancées qui entrainent un courant électrique aboutissant à une anode circulaire (20) entourant le foyer. Le circuit d'utilisation est branché entre l'anode et le dispositif métallique (6) utilisé comme focalisateur du faisceau laser.
Abstract:
The invention relates to an electrostatic fusion reactor composed of a spherical chamber in which vacuum is produced by means of vacuum pumps. The internal wall of the chamber is lined with carbon in the form of graphite or diamond. A spark ionizer, composed of two carbon piles connected to a spark voltage source, is placed in the center of the chamber. The inner wall of the chamber and the central ionizer are connected respectively as a cathode and as an anode to a Dirac-pulse high-voltage generator. In use, a spark discharge is generated between the central carbon piles, the erosion of which generates carbon ions. By applying a high-voltage Dirac-pulse between anode and cathode, the carbon ions are accelerated toward and impact the chamber wall with such an energy as to give rise to carbon-carbon fusion reactions. Other types of ionizers and/or ion accelerators can be used. The heat generated by the fusion reactions can be evacuated by a cooling fluid acting on the external wall of the chamber.
Abstract:
A fusion chamber is disclosed which is divided into separate segments which when fitted together form the fusion chamber. Each segment includes a set of tubes arranged in parallel across a front wall of the segment with each tube extending between plenums behind the front wall. Fluid coolant is pumped through the tubing and through a blanket behind the set of tubes to cool the segment.
Abstract:
In one embodiment, a nuclear fusion-generating device includes a cathodic magnet having a polyhedral structure formed from current-carrying leg sections and adapted to generate a multi-poled magnetic field such that the curvature of the magnetic field lines are everywhere convex within a magnet interior region. An ion generating system injects ions into a center of the magnet interior region at energies favoring a nuclear fusion cross-section of the ions. The current-carrying elements can be powered and configured to confine electrons into the center of the magnet interior region to function as a cathode that neutralizes ionic space charges and facilitates ion movement along paths that do not intersect solid structures. The current-carrying elements can be formed with a radial-to-azimuthal aspect ratio that favors increased transparency to the ions without sacrificing magnetic field strength.
Abstract:
Radionuclides are produced with a pulsed neutron flux from a multiple repetition rate staged Z-pinch machine, the pulsed neutron flux is moderated, an activatable radionuclide precursor is exposed to the moderated pulsed neutron flux, and a corresponding radionuclide from the activatable radionuclide precursor is produced. High current pulses are passed through a target plasma of fusible material enclosed in a cylindrical liner plasma composed of a high-Z plasma to generate a magnetic field that compresses the liner plasma, and generates shock waves. The shock implodes the target plasma. The shock front propagates between an outer shock front and an axis of the target plasma so it is heated through shock dissipation and by adiabatic compression due to an imploding shock front produced in the outer liner plasma to fuse light nuclei and generate alpha particles and neutrons. Alpha particles trapped within the magnetic field further heat the target plasma.

A plurality of energy drivers are arranged around the target chamber so as to supply energy to fusion target materia! in the chamber to initiate a controlled fusion reaction of the materia!, releasing energy in the forms of fusion plasma and heat. A plurality of structures for extracting energy from the fusion reaction are provided, and comprise devices to extract high voltage DC power from the fusion plasma; and means to extract thermal energy from the centra! target chamber. Power to the energy drivers may be supplied from high voltage DC power extracted from the fusion reactions. The energy drivers may use an Apodizing filter to impart a desired shape to the wavefront of the driving energy for causing the fusion reactions, to avoid hycirodynamic instabilities.
Abstract:
An acoustic inertial confinement nuclear fusion device is disclosed. The device includes an enclosure that holds a fluid with dissolved alpha emitters. A generator is coupled to the enclosure, and the generator is configured to harmonically drive the fluid in the enclosure to induce an acoustic standing wave in the fluid. The dissolved alpha emitters nucleate bubble clusters in the fluid as the fluid is driven by the generator. Neutrons, tritium and/or gamma rays, are emitted from the fluid, without or with an external source of neutrons.
