Abstract
An apparatus for producing a plasma with a direct current. A nonmetallic first electrode, having a first surface and a second surface, has pores formed between the first and second surfaces. A conductive liquid is dispersed within the pores of the nonmetallic first electrode. The conductive liquid provides direct current pathways through the nonmetallic first electrode. A second electrode also has a first surface and a second surface. A direct current source provides a first direct current electrical potential and second direct current electrical potential. A first conductive connector is electrically connected to the direct current source, and is disposed adjacent the first surface of the nonmetallic first electrode. The first conductive connector receives the first direct current electrical potential from the direct current source and provides the first direct current electrical potential to the nonmetallic first electrode. A second conductive connector is electrically connected to the direct current source, and is disposed adjacent the first surface of the second electrode. The second conductive connector receives the second direct current electrical potential from the direct current source and provides the second direct current electrical potential to the second electrode. A plasma generation region is defined between the second surface of the nonmetallic first electrode and the second surface of the second electrode. The plasma generation region receives a gas that forms the plasma when the first electrical potential is applied to the second surface of the nonmetallic first electrode and the second electrical potential is applied to the second electrode. The first electrical potential is conducted by the conductive liquid through the pores of the nonmetallic first electrode to the second surface of the nonmetallic first electrode.
