Patent ID: 7486758

Claim:
A combined plasma flow switch plasma source and liner implosion system employing a single power source and a single switch for producing a compact, intense pulsed neutron source based on thermonuclear reactions in compressed plasma, said system comprised of: a. a plasma flow switch plasma source comprised of: (1) a coaxial pair of electrodes, said coaxial pair of electrodes consisting of a first electrode and a second electrode, said first electrode being a truncated cone and surrounded by said second electrode forming an initially evacuated first cavity, said first electrode having an upper discharge end corresponding to a larger diameter end of its truncated cone and a lower end corresponding to a smaller diameter end, said second electrode having upper and lower ends corresponding to those of said first electrode's upper and lower ends; (2) a thin foil of conductive material connecting said first electrode to said second electrode and dividing said first cavity into a downstream portion of said first cavity corresponding to said upper discharge end of said first electrode and an upstream portion of said first cavity corresponding to said lower end of said first electrode, and said thin foil being located approximately half way between the upstream and downstream portions of said first cavity; c. an ultraviolet baffle between said lower end of said second electrode and said first electrode; d. a reservoir within said first electrode truncated cone with a plurality of holes connecting said reservoir to said upstream portion of said first cavity; e. a source of deuterium-tritium gas mixture; f. a fast valve for the injection of said deuterium-tritium gas mixture into said reservoir; g. a liner implosion system comprised of a cylindrical-like lithium or lithium-coated liner connecting the downstream end of said second electrode to a multi-megampere current source, said liner forming a second evacuated cavity connected to said first cavity at the downstream end of said first cavity, and said liner further having the shape of a nozzle throat at the intersection of said first and second cavities; h. a switch for said multi-megampere current source; and i. means for timing the injection of said deuterium-tritium gas mixture into said upstream portion of said first cavity and the initiation of said mufti-megampere current source whereby said plasma flow switch plasma source injects said deuterium-tritium gas mixture into said second cavity at approximately 2000 km/s as said liner collapses to compress said mixture to high temperatures and densities sufficient to initiate thermonuclear reactions.
