Abstract
A reactor capable of continuously producing activated species of oxygen molecules, specifically those known in the prior art 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. Such species are particularly effective in obtaining ultra smooth surfaces when used as the etching gas in plasma milling of a diamond-like carbon film. The use of a film of this type has been found to be the ideal insulating barrier for construction of high temperature superconducting Josephson junctions. The reactor uses toroidal pipes to generate mutual impingement between a reaction machine and chlorine gas.
