Abstract: 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.
