Striation phenomena in a low temperature atmospheric pressure neon plasma jet by optical emission spectroscopy
Striation phenomena in a plasma flare produced by an atmospheric pressure plasma jet had been observed. In this study, we measured the striation structure in a neon plasma flare by optical emission spectroscopy. As a result, it shows that the emission from the plasma flare is synchronized with the p...

| description | Striation phenomena in a plasma flare produced by an atmospheric pressure plasma jet had been observed. In this study, we measured the striation structure in a neon plasma flare by optical emission spectroscopy. As a result, it shows that the emission from the plasma flare is synchronized with the plasma current. We discuss the temperature estimated from the Boltzmann plot using the two emission lines of Ne I at 692.9 and 724.5 nm whose upper levels are Ne [3p (2p6)] and Ne [3p (2p10)], respectively. This temperature has peaks with a spatial interval of about 0.5 mm, and the peak positions correspond to the spatial variation of the emission intensity. We also discuss the mechanism of the striation phenomena with the estimated temperature, and collisional relaxation between excited and neutral atoms. |
