When changing the initial pressure\nand current rate of rise, channel temperature varies from several\nelectronvolts to hundreds electronvolts. Arc channel radius is several\nmillimeters. But the radius of the discharge chamber greater than the\nradius of the arc channel on approximately order of magnitude. High\nefficiency of gas heating is caused by radiation absorption of\nhydrogen surrounding the arc. Current channel consist from vapor of\nthe initiating wire. At current rate of rise of 109 A\/s and relatively\nsmall current amplitude gas heating occurs due to radiation\nabsorption in the band transparency of hydrogen by the wire vapours\nwith photon energies less than 13.6 eV. At current rate of rise of\n1011 A\/s gas heating is due to hydrogen absorption of soft X-rays\nfrom discharge channel.","references":"[1] Ph. G. Rutberg, A. A. Bogomaz, A. V. Budin, V. A.
