[en] Under filling up the 'AMBAL-U' mirror by plasma from quasi-stationary gas-discharge source without using of an additional heating methods, the hot plasma with density 3x10¹³cm^-3, ion temperature 1 keV, electron temperature 50 eV, and the β-parameter of 6% was obtained. In the case of working with deuterium the output of the thermonuclear neutrons was ∼ 10⁸ neutrons/s. Under the atomic H⁰ beams (E≅ 17 keV, equivalent current 100 A, capture ≅5%) injection into the obtained plasma the population of super ions with an average energy of 5 keV in volume of 4 liters is achieved. The density of this population on the whole volume increases during the injection pulse (200 μs) and becomes higher than 3x10¹²cm^-3 to the end of this period. 15 refs.; 11 figs
