    Research output: Contribution to journalArticle


    Optical emission spectroscopy has been used to study an arc formed over an ice surface. DC positive voltage was applied to a flat ice surface with a 6 cm air gap to initiate electric discharge. Time-resolved spectra were recorded during the propagation of arc along the surface. Excitation temperature was measured using copper and oxygen lines and employing the relative line intensities method.
