Abstract
Uniform direct-current discharges in atmospheric-pressure mixtures of He/N2/CO2 have been achieved by the use of an organic gas additive. Best results were obtained using xylene as an additive with a concentration of 0. 5% in a 90/5/5 gas mixture. Observed current densities were limited by external circuitry, but uniform pulsed discharges with current densities over 3 A/cm2 were obtained when the dc discharge was pulsed.Keywords
