SYSTEM AND METHOD FOR PLASMA GENERATION
A system and method for generating a plasma. A first electrode and a second electrode are disposed adjacent to one another, not touching one another. A first power supply supplies power at the second electrode, and a second power supply generates a magnetic field. A sequencer coordinates a discharge of power from the first power supply and a discharge of power from the second power supply. The first power supply may be is configured such that the discharge of power from the first power supply generates a plasma between the first electrode and the second electrode. The second power supply is configured such that the magnetic field it generates rotates the plasma. Depending upon disclosed relative geometries of the electrodes and the magnetic field, the plasma is shaped alternatively as a disc, a dome, a sleeve, or a polygonal sheet.
1 . A method of creating a free-standing wall of plasma, comprising the steps of:
initiating the formation of plasma that flows through a space between a first location that is defined by a first vertically oriented elongate electrode and a second location that is defined by a second vertically oriented elongate electrode which is spaced from and substantially parallel to said first vertically oriented elongate electrode;
generating an electromagnetic field externally of said plasma that acts on said plasma during said formation of said plasma at said first location wherein said electromagnetic field has Lorentz forces associated therewith which effect rotation of said plasma through said space about an axis; and
balancing of thermodynamic forces and centrifugal forces acting upon the plasma with Lorentz forces associated with said electromagnetic field acting upon the plasma so as to confine said plasma in such a manner so as to form a sheet-like structure extending between said first and second locations.
