During present experiments mass flow rate was changed in two ways: first - by changing initial particle concentration in vacuum chamber and second way - by changing atomic mass of working gas. The main discharge parameters and plasma flow parameters was analysis in depending on initial concentration when integral mass flow rate keeps constant. As follow from Bernoully equation plasma density should increased with decreasing initial working gas concentration. In present experiments mass flow rate keeps constant, but initial different working gas concentration was varied. Helium and argon was applied as working gases, atomic mass of these gases differ in ten times. Thus, to keep integral mass flow rate constant initial concentration, in other words, initial pressure in vacuum chamber was differ in ten times too. Experimentally was shown that average along line of view and average in time plasma density in compression zone practically not depend on initial concentration. This result be explained by integral in space and time scheme of measurements. At the same time compression zone position depends on initial gas concentration, namely it moved from central electrode with decreasing concentration. EUF radiation intensity in wave range 12.2-15.8 nm increased with initial concentration decreasing. In particular, with decreasing initial working gas concentration and keeping integral mass flow rate constant total radiation energy increased from 60-70 mJ from helium plasma to 110 mJ from argon plasma. Maximum value of radiation power increased too from 16-18 kW to 32-36 kW respectively. Product Description popup.authors І.Є.Гаркуша В.Є. Моісеєнко В.В.
