Theoretical and experimental investigation of Z-pinch plasma as the source of a Dowerful pulse of soft x rays for the generation of shock waves in condensed targets

摘要

The results are given of a theoretical analysis of the processes in a Z-pinch plasma in regimes that give rise to a powerful pulse of soft x rays. Attention is devoted to schemes with a double liner. Estimates of the radiation power and spectrum are discussed. The results are used to model processes that take place in the generation of a shock wave when soft x rays interact with a target. Experiments have been conducted on the generation of shock waves with pressures up to 3 Mbar in lead under the influence of soft x rays using the ANGARA-5 device. The results of the experiments are compared with the data of numerical modeling.
