Summary:The experimental conditions were reproduced in numerical experiments. The mathematical model of viscous compressible gas was used to model the gas dynamics of supersonic gas jets. The problem was solved in a two-dimensional axisymmetric setting for argon. The obtained distributions of the main gasdynamic quantities made it possible to detail the flow features and estimate the size of the emission zone, as well as the density level corresponding to this zone. It was demonstrated that the results of calculations qualitatively agree with the experimental data. In addition, it was found that the density level of the emission region with the required extreme ultraviolet intensity factor can be obtained by monitoring the total pressure.
