Atmospheric pressure glow discharge in neon

The dielectric barrier discharge burning at atmospheric pressure usually ha s a filamentary non-homogeneous form. However, it was found that uniform di electric barrier discharge can be generated in helium, nitrogen and in the mixture of argon with acetone under specific conditions. Such uniform disch arge is called atmospheric pressure glow discharge (APGD). We studied diele ctric barrier discharge burning in neon at atmospheric pressure and we foun d that the APGD can also be generated in neon. We measured the electrical c haracteristics of APGD in neon for different voltages and frequencies of po wer supply and different gas flows. We found that higher gas flow stabilize s the APGD and we determined the area of parameters in which the APGD burns . The images of discharges were recorded by a video camera and emission opt ical spectra were measured by a spectrometer. The properties of the dischar ges in neon were compared with the properties of discharges burning in argo n and in the mixture of neon with argon.
