The experimental and simulated optical emissions of an air discharge at atmospheric pressure propagating in a capillary glass tube are compared for two tube radii: 100 and 300 μm. For 300 μm, both experimental and calculated optical emissions show a tubular structure of the discharge. For 100 μm, the emission of the discharge appears to be more homogeneous radially.
