摘要
The experiment on the 22mm liner implosion on Angara-5-1 (45 MA, 90 ns) have been accomplished. The foam preionization by imploding low density gas corona and exploded wires has been investigated. It was found the foam-plasma transition by current pulse without preionization accompanied by sharp azimuthal nonuniformities. The implosion of rare gas corona onto a foam liner improved significantly the uniformity when specific corona mass m(c) with diameter 55 mm was of 0.05m(1). However the soft X-ray yield in double liner scheme was not increase in comparison with gas-puff-foam liner combination investigated in previous research. The first experiment on currentless preionization by soft X-ray radiation of exploded wires have been performed. The improving of azimuthal uniformity and stability was observed.
