Abstract:

A method and apparatus for generating high-density sheet plasma mirrors having a longitudinally slotted cathode, circular in shape, having a inner cavity and a slot of a predetermined width positioned along the length of the cathode. A discharge voltage is applied to the cathode within a vacuum chamber which is backfilled with gasses like oxygen and argon, or mixtures thereof, which in cooperation with a magnetic field, which is higher than the threshold field, causes electrons to flow through the slot in the cathode to an anode, positioned a predetermined distance from the cathode, thereby generating a high-density plasma sheet immersed in the magnetic field of width and thickness proportional to the size of the slot in the cathode.
