Abstract:

The objectives of this study were to investigate the plasma existing in the positive column of an oxygen glow discharge and to determine the physical and chemical processes involved. Recently there has been a renewed interest in the oxygen plasma, an interest generated by the development of the laser. Oxygen has been postulated and used as both the lasing medium and the pumping medium in electrical and electrical-chemical lasers. Also, there has been a continuing interest in efficient production of ozone. Effective utilization of oxygen electric discharges require a knowledge of the oxygen plasma, a plasma which differs from other plasmas in many of its characteristics. For example, electrical glow discharges in oxygen have been observed to exist in two different forms a low electrical impedance form which exhibits an oscillatory behavior and a high electrical impedance form which is relatively stable. The transition between the two forms occurs as a function of current density and gas pressure.
