Dielectric Barrier Discharge was produced by applying high voltage AC source of frequency (10-30 KHz) and potential difference of (0-20) kV across two parallel plate electrodes with glass as dielectric barrier. Optical emission spectroscopy was used for the characterization of the discharge produced at atmospheric pressure. The emission spectra in the range of 200 nm to 850 nm have been analyzed to estimate the electron temperature by line intensity ratio method. The results showed that the electron temperature is about 0.9 eV.

Explosive Event

High resolution temporal observations performed with the SUMER spectrometer on SoHO provide us the opportunity to investigate the electron density variations in the solar mid-transition region due to explosive event-like phenomena. The O IV 1401.16/1404.81 density sensitive line intensity ratio shows a clear increase during a strong explosive event, corresponding to an electron density enhancement of a factor of ~ 3 with respect to pre-event values. This is consistent with recent MHD simulations (2.5 D).
