| 20100109532 | DEVICE AND METHOD FOR PRODUCING AND/OR CONFINING A PLASMA - The invention concerns a device for producing and/or confining a plasma ( | 05-06-2010 |
| 20100181915 | APPARATUS FOR MAGNETIC AND ELECTROSTATIC CONFINEMENT OF PLASMA - An apparatus and method for containing plasma and forming a Field Reversed Configuration (FRC) magnetic topology are described in which plasma ions are contained magnetically in stable, non-adiabatic orbits in the FRC. Further, the electrons are contained electrostatically in a deep energy well, created by tuning an externally applied magnetic field. The simultaneous electrostatic confinement of electrons and magnetic confinement of ions avoids anomalous transport and facilitates classical containment of both electrons and ions. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions ions are fused together by nuclear force, thus releasing fusion energy. Moreover, the fusion fuel plasmas that can be used with the present confinement system and method are not limited to neutronic fuels only, but also advantageously include advanced fuels. | 07-22-2010 |
| 20100194281 | Passive Power Distribution for Multiple Electrode Inductive Plasma Source - Systems, methods, and Apparatus for controlling the spatial distribution of a plasma in a processing chamber are disclosed. An exemplary system includes a primary inductor disposed to excite the plasma when power is actively applied to the primary inductor; at least one secondary inductor located in proximity to the primary inductor such that substantially all current that passes through the secondary inductor results from mutual inductance through the plasma with the primary inductor. In addition, at least one terminating element is coupled to the at least one secondary inductor, the at least one terminating element affecting the current through the at least one secondary inductor so as to affect the spatial distribution of the plasma. | 08-05-2010 |
| 20110127915 | PLASMA CONTAINMENT - A method and apparatus are disclosed for plasma containment. A toroidal vacuum device is filled with the gas. Field coils generate a toroidal magnetic field. An ionizing device ionizes the gas into a plasma. A transformer inductively drives a toroidal first particle current about a toroidal axis that heats the plasma and generates a poloidal magnetic field. The field coils restrict the toroidal magnetic field to a boundary value. The poloidal magnetic field and the toroidal magnetic field motivate the first particles radially inward toward a toroidal axis, producing a radial electric field. The radial electric field, the poloidal magnetic field, and the toroidal magnetic field contain the plasma within the toroidal vacuum device in a minimum-energy state. | 06-02-2011 |

| 20140265857 | APPARATUS AND ARRANGEMENTS OF MAGNETIC FIELD GENERATORS TO FACILITATE PHYSICAL VAPOR DEPOSITION TO FORM SEMICONDUCTOR FILMS - Embodiments relate generally to semiconductor device fabrication and processes, and more particularly, to an apparatus and arrangements of magnetic field generators configured to generate rotating magnetic fields to facilitate physical vapor deposition (“PVD”). In one embodiment, a magnetic field generator apparatus can include a rotatable magnetic field and a counterbalance magnetic field generator that rotates about the axis of rotation in opposition to the rotatable magnetic field generator. The rotatable magnetic field generator generates a first magnitude of a magnetic field adjacent to a first circumferential portion of a circular region. The counterbalance magnetic field generator generates a second magnitude of the magnetic field adjacent to a second circumferential portion. The rotatable and counterbalance magnetic field generators can be configured to generate the magnetic field between the first and a second plane along a diameter extending from the first circumferential portion to the second circumferential portion. | 09-18-2014 |
| 20150097487 | Plasma Confinement Device - A device and method for magnetic field confinement of plasma is formed by a cylindrically stacked column of direct current-carrying magnetic field coils with electrodes adjacently interior to each magnetic field coils so as to induce plasma rotation about an annular confinement region. Each field coil produces a magnetic field alternating in direction relative to adjacent coils and, so as to maintain consistent overall azimuthal direction of plasma rotation, electric field electrodes alternate accordingly in polarity along the axial length of the device. The device may be used for inducing nuclear fusion, for the ionic or isotopic separation of elements, creation of thrust by ejecting mass along the axial direction of the device, for creating a gravitational acceleration field, and for creating a state change beyond plasma. | 04-09-2015 |

Electrodes are formed such that the electric fields produced are tangential to the magnetic fields, and so as to maintain consistent azimuthal direction of plasma rotation, electric field electrodes alternate accordingly in polarity along the axial length of the device. | 02-04-2016 |
