Abstract
Electric discharge method and apparatus for producing a relatively large volume, diffuse glow gas discharge plasma for laser, chemical synthesis and other applications at high power, high pressure and high volume levels and such that plasma properties are dominated by collision processes and wherein the operational parameters of the electric discharge are established to provide an average gas residence time T.sub.R in a continuous wave convective electric discharge and a discharge duration time T.sub.P in a pulsed electric discharge that is approximately equal to the plasma instability growth time T.sub.G = CP/JE where P is the pressure in Torr, JE is the electric power density in Watts/cm.sup.3 and C is a constant typically about 10.sup.-.sup.4 for self-sustained gas electric discharges and 10.sup.-.sup.3 for externally sustained gas electric discharges and wherein the convective electric discharge apparatus have a flow baffle system with a transverse foamed plastic baffle and a transverse turbulence generator plate for establishing an approximately isotopic and uniform turbulent flow pattern in the electric discharge region and such that T.sub.R and T.sub.G are representative of local values.
