Title: | Time-space resolved measurement of electric field in dielectric barrier discharge in helium | Authors: | Obradović, Bratislav Ivković, Saša Cvetanovic, Nikola Kuraica, Milorad Puric, Jagoš |
Issue Date: | 1-Jan-2010 | Journal: | HAKONE 2010 - 12th International Symposium on High Pressure Low Temperature Plasma Chemistry | Abstract: | Diffuse DBD in helium was investigated using time-space resolved optical emission spectroscopy. Using emission spectroscopy technique based on the polarization-dependent Stark splitting and shifting of He I 492.19 nm line and its forbidden component, the electric field distribution in the cathode region of DBD in helium is measured during evolution of the discharge. During the whole discharge development period the length of the cathode fall region decreases. Interesting result was that in the period of current decrease, the maximum of the electric field distribution shifts away from the cathode showing the accumulation of negative charge near the cathode surface. |
