Abstract: Present work presents calculations and experimental studies on the formation and dynamics of plasma onthe “plasma focus” set up. Physical conditions were determined and critical parameters were calculatedfor estimating the neutron yield for kilojoule and megajoule set ups. The results of plasma diagnostics andflow formation in the CPA-30 and PF-4 set ups are also shown. A comparison of calculated data andexperimental values is performed. The value of the neutron yield parameter is justified and the possiblecause of the appearance of saturation is indicated. The rationale for the development of further research inthe direction of creating conditions for thermonuclear fusion in installations of the plasma focus type isgiven. The neutron flux was observed on high-voltage gas discharges with a specific geometry of theelectrodes. The result of measuring the anisotropy of the neutron yield along the axial z and radial φdirections was equal to Yn(z)/Yn(φ)~ 2 ÷ 3, which contradicts the thermonuclear mechanism.
