“…To achieve such a power level during current implosion of cylindrical wire arrays, it is necessary to increase the amplitude of the discharge current of a pulse power facility to a level of 50 MA and to carry out work to optimize the load design. For this, a new generation of pulse power facilities with petawatt electrical power (∼500-1000 TW) is currently being designed: BAIKAL, EMIR (in Russia) and X-1 (in the USA) with a current level of 50-70 MA and a rise time of ∼100-800 ns [22][23][24][25][26].…”

The results of experiments on the study of plasma compression of nested wire arrays of mixed composition and the generation of powerful pulses of soft X-ray radiation (SXR), carried out on a powerful electrophysical facility Angara-5-1 at a current level of up to 3 MA, are presented. Based on the latest experimental data on the intensity of plasma formation of various substances m& (in μg/(cm2×ns)) [1] and on the features of the dynamics of plasma compression in nested arrays [2], a nested wire array design has been developed which makes it possible to obtain a high peak SXR power in comparison with the known designs of single and nested tungsten wire arrays. During the implosion of nested arrays of mixed composition, consisting of plastic fibers and tungsten wires, shorter and more powerful SXR pulses were obtained with a maximum peak power PSXRmax~10 TW with a FWHM duration of ~5 ns compared to the parameters of SXR pulses upon compression of single tungsten arrays: PSXRmax~5 TW and FWHM~10 ns. Thus, under the conditions of our experiments, we have shown the possibility of a twofold increase in the peak SXR power during compression of nested arrays by optimizing their design.
