    Diffuse volume-discharges without pre-ionization formed in SF6 and C2H6 mixtures

    It has been shown that a volume discharge is forming in non-uniform electric-field rough cathode and even anode without pre-ionization in SF6 and C2H6 mixtures. The discharge is presented with many diffuse channe...
