Abstract

A reactor capable of continuously producing activated species of oxygen molecules, specifically those known as "Delta Singlet Oxygen". Uses of "Delta Singlet Oxygen" include the maintenance of high oxidation potential during the deposition of layers of high temperature superconductors. Delta singlet oxygen is particularly effective in obtaining ultra-smooth surfaces when used as the etching gas in plasma milling of a diamond-like carbon film. The film can be used as an ideal insulating barrier for construction of high-temperature superconducting Josephson junctions.
