Abstract: Methods and systems are provided for increasing energy output from Z-pinch and other plasma confinement systems. In one example, a system may include memory storing instructions that, if executed by one or more processors, cause the system to adjust one or more parameters to generate a magnetic field which is sufficiently strong to axially compress a fuel gas to induce thermonuclear fusion and increase a fusion energy gain factor greater than a fusion energy gain factor limit attainable by the thermonuclear fusion. In certain examples, adjusting the one or more parameters may include adjusting a duty cycle of a discharge current applied to the fuel gas based, at least in part, on an amount of thermal collisions between fusion byproducts and the fuel gas. In certain examples, by adjusting the duty cycle, the magnetic field may be adjusted to induce or increase the thermal collisions.

Abstract: Methods and systems are provided for plasma confinement utilizing various electrode and valve configurations. In one example, a device includes a first electrode positioned to define an outer boundary of an acceleration volume, a second electrode arranged coaxially with respect to the first electrode and positioned to define an inner boundary of the acceleration volume, at least one power supply to drive an electric current along a Z-pinch plasma column between the first second electrodes, and a set of valves to provide gas to the acceleration volume to fuel the Z-pinch plasma column, wherein an electron flow of the electric current is in a first direction from the second electrode to the first electrode. In additional or alternative examples, a shaping part is conductively connected to the second electrode to, in a presence of the gas, cause a gas breakdown of the gas to generate a sheared flow velocity profile.

Abstract: A cable for carrying electrical current in a coil of a magnet. The cable comprises a stack of tape assemblies. Each tape assembly has a length and a width, such that the length is much larger than the width, and each tape assembly comprises an HTS layer of anisotropic high temperature superconductor, HTS material, wherein a c-axis of the HTS layer is at a non-zero angle to a vector perpendicular to the plane of the HTS layer. The tape assemblies are stacked as a series of pairs, each pair comprising first and second HTS tape assemblies and a copper layer therebetween. The tape assemblies in each pair are arranged such that the c-axis of the HTS layer of the first HTS tape assembly of each pair have reflective symmetry to the c-axis of the HTS layer of the second HTS tape assembly of each pair about a plane which is parallel to and equidistant from each HTS layer.

Abstract: Systems and methods are disclosed herein relating to fusion reactors for fusing particles via multiple periodic collisions. A fusion reactor may include a first evacuated region, such as a chamber, with a plurality of charged particles therein. A uniform magnetic field may be applied to the region to radially confine moving charged particles within the region by inducing circular trajectories. Upper and lower electrodes may be positioned on ends of the region to axially confine charged particles within the region. An energizing beam may be pulsed at a cyclotron frequency corresponding to the mass and charge of the particles to cause oscillating periodic collisions of the particles along the beam path as the particles travel in the circular trajectories with increased velocity after each pulse of the energizing beam.

Abstract: A cooling system for use in a superconducting magnet comprising a high temperature superconductor, HTS, coil. The cooling system comprises a refrigeration unit, one or more coolant channels, and a pumping unit. The refrigeration unit is configured to cool a gas, wherein the gas is hydrogen or helium. The one or more coolant channels are configured to be placed in thermal contact with components of the superconducting magnet and to carry said gas. The pumping unit is configured to pump said gas through the coolant channels. The refrigeration unit and pumping unit are configured to maintain the gas at a pressure and temperature such that a Joule-Thompson coefficient of the gas is positive, and the coolant channel is configured to reduce the pressure of gas as it flows through the channel by one or more of a throttle, a valve, and choice and/or variance of a cross section of the coolant channel.

Abstract: Embodiments of a plasma fusion energy reactor based on Bussard's Polywell concept. The apparatus of the embodiments include interior, electron-extraction electrodes to remove cold, trapped electrons and replace them with hot electrons. Hot electrons efficiently confine a dense, hot plasma fuel. The method of the embodiments discloses a procedure for controlling the reactor during its start-up phase of operation. During start-up the reactor is changed from being in a cold, empty state to being in a stable steady-state of energy production. Reliable computer simulation predicts that in steady-state the disclosed apparatus and method will produce usable net-power continuously and for an indefinite period of operation. The full-scale reactor design is suitable for replacing most of the world's existing coal-fired power production with a clean, safe energy production alternative.
