    Abstract

    Results of spectroscopic investigation of an arc formed over an ice surface are presented. Direct-current positive voltage is applied to a flat ice surface with a 6-cm air gap to initiate electric discharge. Time-resolved spectra are taken during
    the propagation of arc along the surface. From the emission spectra, the profile of hydrogen-alpha from Blamer series is used to measure the electron density of the arc column. A method based on broadening of the Ha line considering instrumentation broadening is employed.
