Abstract

A hybrid load consisting of the deuterium gas-puff with an outer plasma shell and titanium wires located on the axis of the system was studied in the experiments on the GIT-12 generator. The purpose of the research was to obtain experimental data on the efficiency of a plasma radiation source capable of producing radiation with quantum energy of 4.5 keV and higher. The experiments were performed on the GIT-12 generator (4.7 MA, 1.7 μs) without the use of plasma opening switches. During the experiments, the parameters of the deuterium shell and the outer plasma shell remained fixed. They determined the peak current and the implosion time: 2.7 ± 0.1 MA and 740 ± 50 ns, respectively. The number, total mass and relative position of titanium wires were varied. The maximum radiation yield in the titanium K-lines was 220 J/cm at a radiation power of 60 GW/cm. The result was obtained using the array of three wires located on the axis without a gap. The efficiency of the plasma radiation source was determined as the ratio of the experimental radiation yield to the theoretically expected radiation yield calculated using the two-level model, and for the best shot it was only 0.29. For comparison, in experiments with the hybrid load using aluminum wires, the efficiency of the plasma radiation source in the K-lines of aluminum was 1.2. Thus, the transition to an element with a higher atomic number (from 13 to 22) led to a fourfold drop in the efficiency of the plasma radiation source.
