Patents by Inventor Xian-Jun Zheng

Xian-Jun Zheng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10643753
    Abstract: A particle beam emitter has a hollow particle beam tube having a first end portion, a second end portion, and a longitudinal axis. An electromagnetic system that includes a voltage supply is electrically coupled to the hollow particle beam tube and is configured to generate a primary electrical current flowing axially in the hollow particle beam tube from the first end portion towards the second end portion. A primary magnetic field associated with the primary electrical current is operable to induce a secondary electrical current in a plasma located within the hollow particle beam tube, the secondary electrical current flowing generally axially within the plasma and causing the plasma to contract inwardly towards the longitudinal axis.

  • Publication number: 20170294238
    Abstract: A system for generating a source of neutrons from a thermonuclear fusion reaction includes a reaction chamber and a number of particle beam emitters. The reaction system has at least four particle beam emitters supported spatially around oriented toward a common focal region of the reaction chamber for directing the plurality of plasma beams that are spatially symmetrical in three dimensional space. Each of the plasma beams are directed towards a plasma region in the geometric center. A stable collapse of the plasma region permits a controllable and sufficiently long confinement time, which in combination with necessary temperature and density conditions may ignite and sustain fusion reactions and achieve a net energy output. Optionally, laser beams or other input energy devices may also be oriented around and toward the common focal region to direct high-energy laser beams at the plasma ball to assist with instigation of the fusion reaction.

  • Publication number: 20130058446
    Abstract: A thermonuclear reaction system for generating a thermonuclear fusion reaction includes a reaction chamber and a number of particle beam emitters. The particle beam emitters are supported spatially around oriented toward a common focal region of the reaction chamber. The particle beam emitters accelerate energized particles of at least one thermonuclear fuel type, such as hydrogen or deuterium, into the reaction chamber as a plurality of particle beams converging at the common focal region. When the high-energy particle beams converge at the common focal region, the resulting plasma ball is sufficiently dense and hot that a thermonuclear fusion reaction is instigated and thereafter sustained by the energy release accompanying the fusion reactions. Optionally, laser beams or other input energy devices may also be oriented around and toward the common focal region to direct high-energy laser beams at the plasma ball to assist with instigation of the fusion reaction.
